how to solve error :This code is unreachable - in pycharm

x = True

def myFunc():
    if x:
        return "yes"
    else:
        return "false"

    print("hello world")
myFunc()

This code gave me error as: "This code is unreachable"

Please can you explain why this is ?

Solution

  • With return keywords, the def stops when the code runs into a return line. It assigns the specified value to the function, and then it will stop. In your case, you have a bool type on an if/else condition. So x must be True or False, and both cases have a return statement. If you want to do anything after that, you should call it outside the original function.

    So, with that being said:

    x = True

def myFunc():
    if x:
        return "yes"
    else:
        return "false"

myFunc()
print("hello world")

    Hope this helps.
