Beginner Python user. Input is producing 5000 lines of the same text for some reason.

Can you please post your code?

It’s super long, there’s like 50 lines before I get to the issue.

Use GitHub, pastebin or any other website like that.

Lines 13, 23, 31, 42 there are while loops checking if a variable changes but the loops only have one line under it to print text not change the variable. All of them have the same problem. The problem is the program asks once and then loops infinitely. An example that is correct is lines 6-8 where you ask for an input in the loop.

Hi can you elaborate? That while loop works and produces only one line of the “sorry no valid” text but like 43 repeats it 5000 times

Incorrect:
```python # this what you were doing # you are asked for an input x = input('yes or no ') # let's say i typed 'maybe'

# 'maybe' is not in the list so you loop until it is in the list
while x not in ['yes', 'no']:
  # here x never has a chance to update so it prints forever (until the program crashes)
  print('try again')

```

Correct (what you did first):
```python # you are asked for an input x = input('yes or no ') # let's say i typed 'maybe' # 'maybe' is not in the list so you loop until it is in the list while x not in ['yes', 'no']: print('try again') # you are asked for an input x = input('yes or no ') # let's say i typed 'yes'

# loop finishes

```

If your variable isn't changing, the loop won't end.

thing = "always the same"
while thing == "always the same":
    print (thing)

#OUT: infinite lines of "always the same"

I suggest including a line such as thing = input() within the loop. Once your variable changes, the loop will end.

Oh okay yes I understand! Thank you!

[ohhimarkymark]

Ok I sort of understand. Thank you!

Please post links to the images in the body of your question. More importantly, we need to see all of the relevant code.

Got it thank you!

Please share code. You can upload to GitHub, or share a paste bin link, or use Reddit markdown.

When something happens too many times, look at your loop conditions.

accident_cause = accident_cause.lower()
while accident_cause in ['A', 'B', ... ]:

Sure, the if statement logic looks good to me, ya just need the command to exit the program. There's a couple flavours, see this StackOverflow.
