Do break operators turn while loop conditions from True to False?

[Drone4four]

Check out this very basic while loop in Python:

while True:
    response = input("Say something: ")
    if response == 'bye':
        break
    if response != 'bye':
        continue    

This script prompts the user for input. If the user would like to say hello (or really just about anything), the loop will continually prompt the user for a new response until the user finally enters: "bye". If the answer is "bye", the loop breaks.

My million dollar question for all of you: For the purpose of while loops in general, is it safe to say that the break operator turns a while condition from True to False, therefore exiting the loop?

I realize that lines 5 and 6 really aren't necessary because even without them the loop would continue to perform as I described above. I added the continue operator to demonstrate the distinction between break (turning the while condition to False) and 'continue' (allowing the while condition to remain True).

In case I need to refer back to the source or origin of this question, I got this idea from Andrei Neagoie's Udemy course content for "Complete Python Developer in 2019" (Section 4: Lecture 71: "While Loops 2").

No.
It breaks out of the loop in which it is found. It does not change the conditional from any perspective. Trying to explain it that way will just confuse everyone involved.

Hi!

I agree with Mekire. The loop breaks because the program reaches the line 'break' and executes it, not because as you might think, it has changed a previous condition. The previous condition remains True. The only thing that has happened is that the program reaches a line inside the loop, and executes it. It's like if you change the 'break' line to:

print(f"This is still inside the 'True' loop. This is still the condition being 'True'.")

It reminds me of words and maths games, where while applying logic, they try to trick the listener (or reader).

Let's consider a mathematical fallacy. A mathematically correct result derived by incorrect lines of reasoning. Such arguments (it doesn't matter if the final result is true), are mathematically invalid:
16/64 = 16/64 = 1/4

The 16/64 has been simplified to 1/4, not because you have crossed out the number '6' from the numerator and denominator of the fraction, but because you have divided both terms of the fraction by the number '16'.

https://en.wikipedia.org/wiki/Mathematical_fallacy

So, while you might get inclined to think that the reason for breaking the infinite 'True' loop, is because it has stopped being 'True', that reasoning is wrong, because, the loop continues being 'True', and as it is, it reads one line inside of it and executes it, be this line a command to finish (break), be this line any other command, like printing something.

All the best,

Mekire answered to your question. Just to add it's easy to check and you can (and should have) did it yourself:

spam = True
while spam:
    break
print(spam)

Output:
True

while True:
    print('before break')
    break
    print('after break')
print('break after while loop')

Output:
before break
break after while loop

as you can see it exit the loop immediately at executing break statement, not finishing the current loop iteration, nor reaching while to evaluate supposedly changed condition.

Firstly, @newbieAuggie2019: I appreciate the time and care you put into answering my initial question. I really like your angle with the reference to the Mathematical fallacy on Wikipedia because, as a matter of fact, I did my undergrad in Philosophy with a specialty in rhetoric. Rhetoric means that my primary focus was on writing prose while managing and avoiding invocation of logical fallacies. There are literally hundreds of named fallacies and I had never encountered like the Mathematical one that you refer to. I enjoyed reading the Wikipedia entry. I now see my error in reasoning with the way the state or truth proposition of while loops remain unchanged with a break statement. Thanks for breaking it all down and making it relevant to my question about while loops.

@Mekire and @buran: Thank you for your patience with my novice question and for clarifying that the break statement exit loops without impacting a while condition.

I would have liked to have replied sooner but today right now is my first opportunity. Sorry for the delay.
