How to break this loop? (python)

    available_fruits = ['apple', 'grape', 'banana']
    
    choice = input('Please pick a fruit I have available: ')
    
    while True : choice= input('You made an invalid choice. Please pick again:') 
            if choice not in available_fruits 
                 else print('You can have the fruit')

I want to make this loop stop when user inputs something in the list "available_fruits". But when I enter 'apple', it says "You can have the fruit" but as well as "You made an invalid choice. Please pick again:" again.

How can I make this loop to stop when I enter the fruit which is in the list? when I put the "break" at the end of the code, it says its an invalid syntax..

I don't know if its the formatting of your question of if that's your actual code. You some have syntax errors:

  • At the end of every if or else you need to use : as you did with the while condition.
  • You must use the correct indentation.

Once you fix those errors, check the condition you want to meet in order to get out of the loop with break.

This would work:

available_fruits = ['apple', 'grape', 'banana']

choice = input('Please pick a fruit I have available: ')

while True:
    if choice in available_fruits:
        print('You can have the fruit')
        break
    else:
        choice = input('You made an invalid choice. Please pick again: ')

But in general I'd suggest you create while loops with an actual condition. That's what while-loops are for. They automatically break when the condition evaluates to False. It's much cleaner, too.

Example:

available_fruits = ['apple', 'grape', 'banana']

choice = input('Please pick a fruit I have available: ')

while choice not in available_fruits:
    choice = input('You made an invalid choice. Please pick again: ')

print('You can have the fruit')

Give this a try. Assuming you need to use break.

available_fruits = ['apple', 'grape', 'banana']

choice = input('choose a fruit: ')
while True : 
    if choice in available_fruits:
        print('you picked a valid fruit')
        break
    else:
        choice = input('choose a fruit: ')

Use the while condition instead of just while True, something like this works:

available_fruits = ['apple', 'grape', 'banana']

choice = input('Please pick a fruit I have available: ')

while choice not in available_fruits: 
    choice= input('You made an invalid choice. Please pick again:')

print('You can have the fruit')
