What are some examples of while loops in Python?

What are some examples of while loops in Python?

Sure! A while loop in Python repeatedly executes a block of code as long as a specified condition is true. Here's a simple example:

count = 0
while count < 5:
    print(count)
    count += 1

This will print numbers 0 to 4.

Can you give me another example that uses user input?

Absolutely! Here's an example that continues to ask for user input until they type 'exit':

user_input = ''
while user_input != 'exit':
    user_input = input('Type something (or type exit to quit): ')
    print('You typed:', user_input)

What happens if the condition is never false?

If the condition never becomes false, the while loop will create an infinite loop, which can cause your program to hang. It's important to ensure that the loop has a way to exit.

How can I prevent infinite loops?

You can prevent infinite loops by ensuring that the loop's condition will eventually become false. For example, always update the variables involved in the condition within the loop.
