DEF function in Python
- The Python Def function is the User-Defined one.
- Function blocks start with the keyword def then followed by the function name and parentheses ( ( ) ).
- Any input parameters must place inside the parentheses. Now you can define parameters inside the parentheses.
- The initial statement of a function is optional statement – the documentation string of the function (docstring).
- Within the code block each and every function begins with (:) colon and is indented.
- The statement return [expression] exits the function, alternatively passing back the expression to caller. The return statement with no arguments is the similar as return none.
Syntax:
def functionname( parameters ):
"function_docstring"
function_suite
return [expression]
