numpy.diff() is a function of the numpy module which is used for depicting the divergence between the values along with the x-axis. So the divergence among each of the values in the x array will be calculated and placed as a new array. These difference values for the arrays can be calculated across up to n number of times. so this means the disparity between the given values can be effectively estimated across multiple levels of the arrays.

a = The array which is keyed in for determining the difference across the elements of the array.

n = Represents the entire number of times the differentiation process needs to be carried upon.

append, prepend = If some value needs to be appended or prepended to the values in the x-axis then these parameters are been used. here the difference will be calculated just before the append or the prepend process.

How numpy.diff() Works?Consider an input array Test, the occurrence of the first difference for the input array is calculated using the formula out[i]=Test[i+1]-a[i]. The diff() again on this array helps to calculate the higher difference values.

The numpy is used on top of a one-dimensional numpy array. here the one-dimensional array has only a single-dimensional set of elements to it. But there could be instances where it needs to be substituted over a two-dimensional array too. from a different perception, there are situations where the numpy element need to be substituted over a two-dimensional array also. these two-dimensional arrays are in other words termed as multiple axes.

So at the point of implying diff() function over two-dimensional axis arrays then we rely on the use of the argument called an axis. here the value specified for the axis argument will be representing the columns of the two-dimensional array. so as like mentioned before at the point of applying the diff() function execution the initial column in the array undergoes a transformation which is very similar to below.

Sample array,

[0, 1, 1], [7, 3, 15], [8, 3, 11]

[0, 1, 1], [7, 3, 15], [8, 3, 11]

Difference value for the first row in the two-dimensional array will be taken forward as like below.

[0 1 1] difference = [1 0]

[1 0] difference = [-1]

The same process will be extended upon each and every row in the array,

Examples of numpy.diff()Following are the examples are given below:

Example #1 import numpy as np Date_array = np.arange('2024-09-01', '2024-09-05', dtype=np.datetime64) output_diffrence = np.diff(Date_array) print("The difference in date value is: " + str(len(output_diffrence)) +" days ")Output:

Code Explanation: The above program uses numpy library for determining the difference of days within two date values in an array. the program begins with an import of the numpy library using the alias name as np. the np.arrange() method is used for creating an array element, the array element formulated in the arrange function is based on the below syntax.

numpy.arange([start_value, stop_value, n_value,dtype=None)here the first two indexes refer to the start and stop value whereas the third type mentions the data type which is been used. In this case for determining the expanded array of dates, the arrange method is filled with the start and the end date values. Both the date values are maintained in the YYYY-MM-DD format. so all dates falling within this are determined and formulated as an array. the formulated array is passed as input to the np.diff() function. so the np.diff() function is responsible for determining the difference in date values between each and every item in the formulated array. so once the difference value is determined it is depicted as an array. we have additionally used the len() function to determine the length of the array. based on the length of the array the number of days is determined. The determined number of days is populated in the print console as output.

Example #2Code:

import numpy as np array_var = np.array([1,2,5]) print("Array value:",array_var) output_diffrence = np.diff(array_var) print("The diffrence value is: ",output_diffrence )Output :

Next, the array variable is passed as input to the np.diff() function. As we already know this np.diff() function is primarily responsible for evaluating the difference between the values of the array. the degree of difference can be depicted next to this parameter. based on the degree of difference mentioned the formulated array list will get hierarchal determined for its difference. the derived output is printed to the console by means of the print statement.

Example #3Code:

import numpy as np array_var = np.array([[1, 7, 4, 12], [4, 2, 4, 8]]) print("Array value:",array_var) output_diffrence = np.diff(array_var,n=2) print("The diffrence value is: ",output_diffrence )Output :

Code Explanation: The given program is used for formative the disparity of value between a given set of two different arrays, So the program starts with a header import of numpy module as alias name np. the array function is used for creating an array with the necessary set of values and data types are handily specified. Again as like before here too the returned value of the array function is stored in a variable of name ‘array’. This particular variable is accountable for holding the array values and the value held by this array set of the variable is displayed in the console. The necessity for performing the array function conversion in these diff() function processing is because there is a need to convert a list of values passed into a-axis oriented representation.

ConclusionThe above content nicely mentions the necessity of np.diff() function in python oriented programming for axis level difference calculation. Also additionally a set of three different techniques for implementing np.diff() is also discussed.

## Guide To Namedtuple Python With Examples

Introduction to Namedtuple Python

Web development, programming languages, Software testing & others

Working of NamedtupleAs tuple has an integer index to access as they have no names, there might be ambiguity to store and access the data to that particular integer index. Tuples are an ad-hoc structure that means if two tuples have the same number of fields and the same data stored, there is an ambiguity for accessing. So to overcome all such problems, Python introduces Namedtuple in the collections module. Python has containers like dictionaries called namedtuple(), supporting access to the value through key similar to dictionaries. Namedtuple is the class of collections module which also contains many other classes for storing data like sets, dictionaries, tuple, etc.

Nametuple is an extension to the built-in tuple data type, where tuples are immutable, which means once created, they cannot be modified. Here it shows how we can access the elements using keys and indexes. To use this namedtuple(), you should always import collections in the program. Namedtuples offers a few users access and conversion methods that all start with a _ underscores. Namedtuple is mostly used on unstructured tuples and dictionaries, which makes it easier for data accessing. Namedtuple makes an easy way to clean up the code and make it more readable, which makes it a better structure for the data.

There are different access and conversion operations on namedtuple.

They are as follows:

Access operations on Namedtuple() which we can access values using indexes, keys, and getattr() methods.

Access by index: In this, the values are accessed using index number because the attribute values of namedtuple() are in order so indexes can easily access it.

Access by keys: In this, the working is similar to a dictionary where the values can be accessed using the keys given as allowed in dictionaries.

Access using getattr(): This is one of another method in which it takes namedtuple and key-value as its argument.

Examples of Namedtuple PythonGiven below are the examples mentioned:

Example #1Code:

import collections Employee = collections.namedtuple('Employee',['name','age','designation']) E = Employee('Alison','30','Software engineer') print ("Demonstration using index, The Employee name is: ",E.name) print ("Demonstration using keynames, The Employee age is : ",E[1]) print ("Demonstration using getattr(), The Employee designation is : ",getattr(E,'designation'))In the above example, firstly, we create namedtuple() with tuple name as “Employee”, and it has different attributes in the tuple named “name”, “age”, “designation”. The Employee tuple’s key-value can be accessed using 3 different ways, as demonstrated in the program.

There are some conversion operations that can be applied on namedtuple().

They are as follows:

_make(): This function converts any iterable passed as argument to this function to namedtuple() and this function returns namedtuple().

_asdict(): This function converts the values of namedtuple that are constructed by mapping the values of namedtuple and returns the OrderDict().

** (double star) operator: This operator is used to convert to namedtuple() from the dictionary.

_fields: This function returns all the keynames of the namedtuple that is declared. We can also check how many fields and which fields are there in the namedtuple().

_replace(): This function replaces the values that are mapped with keynames that are passed as an argument to this function.

Example #2Code:

import collections Employee = collections.namedtuple('Employee',['name','age','designation']) E = Employee('Alison','30','Software engineer') El = ['Tom', '39', 'Sales manager' ] Ed = { 'name' : "Bob", 'age' : 30 , 'designation' : 'Manager' } print ("The demonstration for using namedtuple as iterable is : ") print (Employee._make(El)) print("n") print ("The demonstration of OrderedDict instance using namedtuple is : ") print (E._asdict()) print("n") print ("The demonstration of converstion of namedtuple instance to dict is :") print (Employee(**Ed)) print("n") print ("All the fields of Employee are :") print (E._fields) print("n") print ("The demonstration of replace() that modifies namedtuple is : ") print(E._replace(name = 'Bob'))Output:

The above program creates the namedtuple() “Employee” and then it creates iterable list and dictionary “El” and “Ed” which uses the conversion operations _make() which will convert the “El” to namedtuple(), _asdict() is also used to display the namedtuple() in the order that is using OrderDict(), the double start (**) which converts dictionary “Ed” to namedtuple(), E.fields which will print the fields in the declared namedtuple(), E.replace(name = “Bob”) this function will replace the name field value of the namedtuple() in this it replaces “Alison” to “Bob”.

ConclusionIn Python, we use namedtuple instead of the tuple as in other programming languages as this is a class of collections module that will provide us with some helper methods like getattr(), _make(), _asdict(), _fileds, _replace(), accessing with keynames, ** double star, etc. This function helps us access the values by having keys as the arguments with the above different access and conversion functions on the namedtuple() class of collections module. It is easier than tuples to use and is very efficient and readable than tuples.

## Syntax And Examples Of Matlab Syms

Introduction to Matlab Syms

In MATLAB, syms is used as a shortcut to the inbuilt function sym. This function can be used to create symbolic variables. The Symbolic variables used in MATLAB are not constants like the regular variables; we do not assign values to them. One important function in this toolbox is the syms function, which creates a symbolic object and automatically assigns it to a MATLAB variable with the same name. This allows for convenient manipulation and evaluation of symbolic expressions in MATLAB.

## Types And Examples Of Control Activities

Introduction to Control Activities Meaning

The term “control activities” (CA) refers to the policies, procedures, and mechanisms put in place by the management of an organization to reduce the risks identified during the risk assessment process. In short, Control Activities refer to the actions taken by the management to either mitigate or minimize risk.

How Does it Work?The CA takes place at multiple levels and across all functions of an organization. It is the responsibility of the management to establish effective and efficient control activities, which can be a preventive, detective, or corrective in nature.

Preventive: These types of CA are relatively cost-effective in nature as these are implemented upfront with the intention to prevent the loss of assets in the first place.

Corrective: Once the detective CA identifies the errors or irregularities, then these types of CA are implemented with the sole intention of fixing the issues at hand. In some cases, overhauling of the existing system is required to put in place a new system to prevent the issues.

Types of Control Activities

Authorization: These types of CA are put in place to ensure that all transactions within the organization are carried out according to the limits and exceptions that have been stated in the policy framework or granted by the appropriate officials.

Review & approval: These types of CA are put in place to ensure that the appropriate personnel reviews all transactions for accuracy and completeness.

Verification: These control activities include various computer and manual controls that are put in place to ensure that all accounting information is captured correctly.

Reconciliation: These control activities include validation of accounting information recorded in systems by comparing them with the source chúng tôi helps in ensuring that the financial records are absolutely correct.

Physical security over assets: These types of CA are put in place to ensure that the assets are protected from losses or damages due to negligence, fraud, theft, natural disaster, accident etc.

Segregation of duties: These types of control activities help in reducing the risk of human error, negligence or fraud by involving more than one person in a particular process.

Education, training & coaching: These types of control activities help in reducing the risk of error due to inefficiency in operations by providing proper education and training to the personnel so that they perform their duties commendably. However, it is important to review the education and training programs periodically to ensure that they remain updated as per the current industrial and organizational practices.

Performance planning &evaluation: These types of control activities establish the key performance indicators that the organization can use to identify the unexpected and unusual changes in trends. These changes can be the precursor of something much worse and hence require deeper investigation. The evaluations are usually carried out at multiple levels within the organization or found appropriate by the management.

Examples of Control ActivitiesNow, let us look at some of the examples to understand how the CA help in an actual organizational set-up.

Example #1 Example #2A particular company designed some new policies to review and reconcile the accounts receivable to ensure timely detection of the delinquent accounts and planning of appropriate actions. The new policies mandate weekly reconciliation of the accounts receivable recorded in the system to the available receipts by the Accountant. The Assistant Controller should then review the reconciliation. At the end of the month, the Account Receivable Supervisor should age the outstanding receivable balances, which the Assistant Controller should then review. Finally, the delinquent accounts should be taken up for further investigation, while the Controller should approve the written-off bad debt.

Conclusion

Control activities are the actions taken by the management at multiple levels and across all functions of an organization to either mitigate or minimize risk.

There are three major types of CA – Preventive control activities, Detective control activities, and Corrective control activities.

Authorization, review & approval, verification, reconciliation, physical security over assets, segregation of duties, education, training & coaching, and performance planning & evaluation some of the most commonly used CA.
