Pattern: Unreachable code

Issue: -

Description

Unreachable code can never be executed because there exists no control flow path to the code from the rest of the program. It is generally considered undesirable for a number of reasons, including increased code size and increased time and effort for maintenance. Consider deleting unused code to resolve this issue.

Example of incorrect code:

def func():
    return 1
    print('unreachable')

Example of correct code:

def func():
    return 1
