The counter variable in file hangman.py line number 36 will not decrease after a wrong attempt. It goes from 5 to 4 on the first attempt but after that for every wrong attempt it stays the same

code for hangman

You've changed your code in that repo and I think you're referring to line 36 in the repo. That being said, python is not pass by reference. When you change counter inside the function read, you're not changing the global variable lives. If you run your program in interactive mode, python -i prac.py, then run print(lives) after you can see it's still at it's original value of 5. A work around to this could be to set the global lives in prac.py as follows:

# original code:
    def func(par):
        x=par

        print(x)
        c1.create_text(100,0,fill='white',text=par)
        flag_3=ob1.read(x,lives)

# new code:
def func(par):
    x=par

    print(x)
    c1.create_text(100,0,fill='white',text=par)
    global lives
    flag_3=ob1.read(x,lives)
    lives = flag_3

A more elegant solution however would probably be to have the lives variable as member of your hangman class.

  • i tried doing that but there was no change and flag_3 is used to check if the string entered is correct or not so the values of flag_3 will be 0 or 1 – agentsam007 Aug 02 '19 at 05:29
  • It works for me: https://imgur.com/a/2XaWOoS In the version of the code I used (hash 03788ba), your `read` function returns counter, which is simply the input arg counter decremented if the guess was incorrect. – mTesseracted Aug 02 '19 at 16:35
  • As a side note, when trying to post to a forum about a bug, you want to make it a [minimal working example](https://en.wikipedia.org/wiki/Minimal_working_example). This way people don't have to comb through a bunch of extra code that is unrelated to the issue. Most times you'll also find the bug when making the minimal example. – mTesseracted Aug 02 '19 at 16:40
