In most Python programs/scripts, you might see a function definition, followed by a conditional statement that looks like the example shown below: def main():įind out our Python Training in Top Cities/Countries India Hence, having a defined starting point for the execution of your Python program is useful to better understand how your program works. This is because the Python interpreter executes from the top of the file unless a specific function is defined. In Python, it is not necessary to define the main function every time you write a program. It essentially serves as a starting point for the execution of a program.
This is nothing but the main function, or main() as it is usually denoted. In most programming languages, there is a special function which is executed automatically every time the program is run. So let’s understand what exactly is the main function in Python. Now, the main function is like any other function in Python. There are three types of functions in Python namely Built-in function, user-defined functions, and anonymous functions. We have already learned that a function is a piece of code written to perform a specific task. They are leveraged to perform computations on the input data and present the output to the end user. What is Python functions?Ī function is a block of reusable code that forms the foundation of performing actions in a programming language. To understand more about python main function, let’s have a look at the topics that I will be covering in this article:
Defining the main function in Python programming is a necessity to start the execution of the program as it gets executed only when the program is run directly and not executed when imported as a module.
The main function in Python acts as the point of execution for any program. Python is one of the most popular programming languages to learn.
