Since Python 3.5, it’s been possible to use@to multiply matrices. For example, let’s create a matrix class, and implement the__matmul__()method for matrix multiplication: classMatrix(list):def__matmul__(self,B):A=selfreturnMatrix([[sum(A[i][k] *B[k][j]forkinrange(len(B)))fo...
The Pandas Series is a one-dimensional labeled array holding any data type(integers, strings, floating-point numbers, Python objects, etc.). Series stores data in sequential order. It is one-column information. Series can take any type of data, but it should be consistent throughout the seri...
Call the friend function from outside the class, passing an object of the class as an argument. Inside the friend function, you can access and manipulate the private and protected members of the class through the passed object. For example, an overview #include <iostream>class Rectangle {priva...
The main difference between Python methods ishow the methods bind to a class. Class methods bind to a class through theclsargument, instance methods bind to instances through theselfargument, while static methods do not bind to a class or an instance. Note:The most common method type in Pyth...
Interfaces with optional properties are written similar to other interfaces, with each optional property denoted by a ? at the end of the property name in the declaration. What is?and Optional Properties? At the end of some non-required property names of the interface, add?This is an optional...

In this example: UserProfile is a TypedDict with specific keys and their corresponding types. The create_user function accepts a user profile as keyword arguments. We can now precisely type-check each argument based on its name. PEP 692 has further information. This feature improves Python's ty...
Ease of use for Python developers. System and platform agnosticism. Let's see a simple example of how to write a Locust load test: ImportHttpUser,task,timeandclasses. Createclass = AuthenticateUserthat takes an argument of theHttpUserclass. ...
