为什么`if`在Python Turtle中不起作用，在我看来我写的一切都是正确的

Question

import turtle
turtle.color ("black", "red")
turtle. speed (10)
while True:
    a = input("введите действие (вперед-w, назад-s, влево-a, направо-d):"))
    if a == "w":
        u = int(input("насколько?:"))
        turtle.forward (u)

enter image description here

if does not work in Python turtle, please help

Почему в Python turtle не работает "IF"?

Answer 1

The initial problem is this line:

а = input("..."))

You have one too many closing parentheses. Try not to confuse the parentheses inside the quotes and the ones outside. Running your code should have produced an error:

SyntaxError: unmatched ')'
