Python Operators are symbols/words that tell the Python Interpreter to perform or execute certain manipulation tasks. The logical operators are used to combine multiple boolean statements. There are three logical operators in Python. and or not Python Logical Operators Flowchart The below image depicts the flowchart of the logical operators. Logical AND Operator in Python […]
When a class inherits from more than one class, it’s called multiple inheritances. Python supports multiple inheritances whereas Java doesn’t support it. The properties of all the super/base classes are inherited into the derived/subclass. Python Multiple Inheritance Syntax The syntax for Multiple Inheritance is also similar to the single inheritance. By the way, the derived
Python class constructor function job is to initialize the instance of the class. Python __init__() is the constructor function for the classes in Python. Python __init__() Function Syntax The __init__() function syntax is: The def keyword is used to define it because it’s a function. The first argument refers to the current object. It binds

Python static method belongs to the Class. They are used to create utility methods for the class. The static method is called from the Class reference. They can’t change the state of the object since they belong to the class. In fact, a static method doesn’t have access to the class attributes. The static method
Python is an Object Oriented Programming(OOP) language. Object Oriented Programming is an essential concept in programming, it allows us to break the programs into reusable components, and implement the concepts like Polymorphism, Encapsulation, Inheritance, and Data Abstraction. The classes and objects are the building block of object-oriented programing. It provides a way to concatenate several
The idea of Python main function is to execute some code only when the Python script is executed directly. The function should not execute when the same script is imported as a Python module in another program. How to Write a Python main Function? When we run a python program, it executes all the statements
Environment variables is the set of key-value pairs for the current user environment. They are generally set by the operating system and the current user-specific configurations. For example, in a Unix environment, the environment variables are set using the user profile i.e. .bash_profile, .bashrc, or .profile files. Environment Variables in Python You can think of

Python command-line arguments are the parameters provided to the script while executing it. The command-line arguments are used to provide specific inputs to the program. What is the benefit of Python Command Line Arguments? Python command-line arguments help us to keep our program generic in nature. For example, we can write a program to process

Python doesn’t have a ternary operator. But, it supports writing an if-else statement in such a way that it works as a Python ternary operator. Why Python doesn’t have a special ternary operator? Many programming languages have ternary operators. But, their main purpose is to reduce the code size by removing simple if-else blocks. Python
Python self variable is used to bind the instance of the class to the instance method. We have to explicitly declare it as the first method argument to access the instance variables and methods. This variable is used only with the instance methods. In most of the Object-Oriented programming languages, you can access the current
