Here’s a basic explanation of how you can create a function in Python: Syntax: def function_name(parameter1, parameter2, …): # Function body – where you write the code that the function executes # Use parameters to perform operations # Optionally, return a value using the ‘return’...
Then we have the name of the function (typically should be in lower snake case), followed by a pair of parenthesis() which may hold parameters of the function and a semicolon(:) at the end. The code inside the function should always be indented because Python relies on indentation to ...
