ValueError: invalid literal for int() with base 10: 'quit'

Question

I keep getting this errror message:

ValueError: invalid literal for int() with base 10

Here is my code snippet

age = {} 
while age != 'quit': 
      age = input('what is your age?') 
      age = int(age) 
      if age >= 18: 
        print("You're old enough to vote.") 
      else: 
        print("You're not old enough to vote.")

Please use **Google Colab **if possible.

I tried the `except ValueError method but it did not work. Maybe I just used it incorrectly:

Answer 1

One of the approach (may not be optimal) is to break the loop once you encounter ValueError. Logic can be similar to this

while age != 'quit':
    age = input()
    try:
        age = int(age)
        if age >= 18:
            print("You're old enough to vote.")
        else:
            print("You're not old enough to vote.")
    except ValueError:
        break
