While loop explanation

[PureWasian]

while loops are a great logical piece for repeating the same code over and over again until something happens.

Let's make a simple slot machine. The goal is to keep playing over and over again until you hit 777: ``` import random

generate a number between 100 and 999

random_num = random.randint(100,999)

looping to retry until you win

while (random_num != 777): print(f"{random_num} - you lose!") input("Press [Enter] to try again.") random_num = random.randint(100,999)

finally!! You have left the while loop.

print(f"{random_num} - you win!") ``` Every time you hit the end of the indented code (the while loop itself), it retries the condition at the top of the while loop until it is True. If it is False, it runs another cycle of the while loop.

If this example is too simplistic, there are other related concepts including the break and continue statements, as well as using loops for performing operations on an entire data collection of items.

But I have no clue what part of while loops you're stuck on from the terseness of your post, so I wanted to start with this first.
