Description

A function parameter should only be read and not be modified. If your intent is to modify the value of the parameter, return the value in the function and handle the new value in the caller of the function.

Non-Compliant Code Examples

def func(arg1, arg2):
	arg1 = foo  # assign to a variable that is an argument
def func(arg1, arg2):
	(arg1, arg3, arg2) = foo  # assign to a variable that is an argument

Compliant Code Examples

def func(arg1, arg2):
	arg3 = foo
