Python functions are blocks of code (multiple program lines) that can perform a specific task like finding an area.
The function is used to reduce the line of code by having a code to perform a task and calling it again instead of writing multiple lines of code repeatedly.
A program can even take in values to perform the operation on, these are parameters.
Python provides many in-built functions and also allows the programmer to create their own functions.
Here, is the syntax for creating a function in Python
def functionName():
# code to be executed in the function
For a function to perform the task you need to call the function,
