Why is my script is opening then closing immediately when it shouldn't? (Python)

Question

I'm trying to make a warmer / colder game in python as a project. Currently, when I open the program it closes immediately despite there being several loops and inputs. I have spent a good 2 hours on it, and I can't figure it out. Any tips?

import random
Correct = random.randint(1, 100)
Oldval = 50
Newval = 50
while Newval != Correct:
    Newval = Newval + input("How much do you want to move?")
    if (Newval - Correct) > (Oldval - Correct):
        print("Colder!")
    else:
        print("Warmer!")
    Oldval = Newval
Win = input(You Win!)

Answer 1

You were trying to add a string and an integer. Also, your final input didn't have quotes around the You Win! string. Here's the code with the issues fixed:

import random
correct = random.randint(1, 100)
oldval = 50
newval = 50
while newval != correct:
    newval = newval + int(input("how much do you want to move?"))
    if (newval - correct) > (oldval - correct):
        print("Colder!")
    else:
        print("Warmer!")
    oldval = newval
win = input("You Win!")

You could use pylint tool to detect the error like missing quotes. pylink test.py

E: 12, 0: invalid syntax (<string>, line 12) (syntax-error)

You could install pylint using pip install pylint
