November 22, 2022I need help in understanding while loop
It's nothing more than a loop that keeps running as long as the condition you give it evaluates to True. If you do while True, you get an infinite loop. If you do white x > 3, you get a loop that keeps repeating as long as the value of x is greater than 3. If you do while someFunction(), you get a loop that keeps repeating as long as someFunction() returns True. If you do while False, it never runs anything at all. This code; x = 3 while x != 0: print(x) x -= 1 print("Done!") Basically performs these steps; Set x to 3 x is not 0, so run the loop once Print x, then decrement it by 1. x is now 2 x is still not 0, so run the loop again Print x, then decrement it by 1. x is now 1 x is still not 0, so the loop runs a 3rd time Print x, then decrement it by 1. x is now 0. x is now 0, so the while loop's condition now evaluates to False and the loop will not run again. Print "Done!" More on reddit.com

August 21, 2023How 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

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()

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.

So, what happens after the else command executes and the value of n gets saved in t? Well, we’re at the end of our loop, so the loop will circle back to its beginning. (Since the conditional for this While loop is True, it will keep running until it encounters a break command.)

This example uses the time.sleep() function to create a 1-second delay between each countdown number. The while loop is a versatile and powerful control structure in Python that can help you manage iterative tasks based on conditions. Here’s a recap of key points: Basic Usage: Use a while loop to repeat a block of code as long as a condition is true. break: Use break to exit a while loop before the condition becomes false. Simulating do while Loops: Python doesn’t have a native do while loop, but you can simulate it using a while True loop with break.

In many ways the object returned by range() behaves as if it is a list, but in fact it isn’t. It is an object which returns the successive items of the desired sequence when you iterate over it, but it doesn’t really make the list, thus saving space. 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():
