Why does the else not work correctly?

Question

I am making a simple hangman game for a class. The current program does every step of the drawings, even if the user gets a correct answer.

import turtle
import random
import sys

while True:
    list = ['report', 'beach', 'mayor', 'score', 'overeat', 'load', 'battery', 'social', 'honor', 'risk']

    turns = 10
    guesses = ''
    err = 0

    usedw = random.choice(list)

    wn = turtle.Screen()
    draw = turtle.Turtle()

    length = len(usedw)

    print("Welcome to hangman your word is", length, "letters long.")

    while turns > 0:
        guess = input("Choose a character: ")
        guesses += guess;
        lengthr = 0
        for char in usedw:
            if char in guesses:
                print (char,)
                lengthr += 1;
            else:
                err += 1;
                if err == 1:
                    draw.goto(0,0)
                    draw.down()
                    draw.goto(200,0)
                elif err == 2:
                    draw.up()
                    draw.goto(0,0)
                    draw.down()
                    draw.goto(0,200)
                elif err == 3:
                    draw.up()

Answer 2

THE PROBLEM is in your in/correct determination logic:

for char in usedw:
    if char in guesses:
        print (char,)
        lengthr += 1;
    else:
        err += 1;
        if err == 1:
            ...

The for iterates through the characters of the word. For instance, if the word is "overeat", you will execute this loop seven times for each guess. Even if the player makes the best guess, "e", you will charge him/her with wrong guesses for the letters "ovrat", and draw five boy parts.

REPAIR

First, you have to determine whether the most recently guessed letter is in the word anywhere:

if guess in usedw:
    print (char,)
    lengthr += 1;
else:
    err += 1;
    if err == 1:
    ...

There are other problems and improvements, but this should get you moving.
