I prefer to use a looping variable, as it tends to read a bit nicer than just "while 1:", and no ugly-looking break statement:
finished = False
while not finished:
... do something...
finished = evaluate_end_condition()

February 13, 2024How do you loop until correct input is given?
First find what loop you need. If the number of iterations is known beforehand then for. If not known then while. Then find how to draw a random number. Test in the python interpreter. Then find how to use the input function. Test in tje python interpreter. Brick by brick you will build you way ;) More on reddit.com

February 25, 2022Why not add do-while loops to Python?
I think the assignment expressions of PEP 572 are being implemented partly because of this. It’s even one of the examples: https://www.python.org/dev/peps/pep-0572/#id22 More on reddit.com

Python Do While – Loop Example
August 31, 2021 - Before any code is run, Python checks the condition (number < 10). It evaluates to True so the print statement gets executed and Number is 0! is printed to the console. number is then incremented by 1. The condition is re-evaluated and it is again True, so the whole procedure repeats until number is equal to 9. This time Number is 9! is printed and number is incremented, but now number is equal to 10 so the condition is no longer met and therefore the loop is terminated.

We say such an object is iterable, that is, suitable as a target for functions and constructs that expect something from which they can obtain successive items until the supply is exhausted. We have seen that the for statement is such a construct, while an example of a function that takes an iterable is sum(): ... Later we will see more functions that return iterables and take iterables as arguments. In chapter Data Structures, we will discuss list() in more detail.

Until Loops and Do While Loops in Python? This is how! | by Better Everything | Medium
August 13, 2024 - To make an Until loop we need to loop until a certain condition evaluates to True. To do that, we can choose between a for loop or a while loop to start repeating lines of code. In the loop we put an if-statement to check a condition.

r/learnpython on Reddit: How do you loop until correct input is given?
February 25, 2022 -
I'm doing an assignment that requires I make a code that creates random numbers in a loop until I give a specific input. I just don't know how to get the loop to run while an input is requested. PLZ HELP!
EDIT:
To clarify the assignment:
Write a program that enters a number of positive integers.
The program ends when the user gives in a negative number.
a) Before the program ends, the largest number is printed.
b) Before the program ends, the smallest number is printed.
c) Before the program ends, the sum of the even numbers and the sum of the odd numbers are printed.
(I can do the a,b,c part no problem. It's the Program that creates the numbers i have problems with)
I asked my teacher what he meant by "a number of positive integers". He stated that the program should create numbers until the negative number is given.
EDIT 2:
I have concluded that I'm an idiot. It is the user who inputs the numbers. Thank you all for the help and not giving up with my dense skull :) (great community👍)

The input() function is "blocking". That means that the code will stop and wait for input. Once you type something and hit enter the code will go to the next line. Executing code at the same time as waiting for input is much harder. You would need to do a non-blocking read. Each time you call the function it will tell you if a character has been entered or not. So you have to keep looping and checking. There's a REALLY good chance you're reading the assignment wrong and it is actually intending for you to use input() and it just does one iteration of the loop for each wrong code.

Note that this loop structure is slightly different than Do While loop structures that appear in other programming languages. Python doesn’t have a built-in Do While loop structure, but the behavior of a Do While loop can be modeled with programs that use While, If and break commands as we’re exploring here.

March 17, 2023 - So in Python, it can be done with a while statement using the break/continue/if statements if the while condition is not satisfied, which is similar to do while loop as in other languages.

November 12, 2024 - While infinite loops can be useful, they should be used with caution to avoid unintentional infinite runs. while True: print("This will run forever unless stopped manually.") This code will continue printing indefinitely until you manually interrupt it, such as by pressing Ctrl + C in most terminals. An interesting feature in Python is that you can pair while with else.
