#While loop python how to
You now know how to create a do while loop in Python. It will continue to loop if a condition is not met and then terminate when a condition is met. So this is how you create the a similar effect to a do while loop in Python. The break statement allows you to control the flow of a while loop and not end up with an infinite loop.īreak will immediately terminate the current loop all together and break out of it. In Python, a basic while loop looks like this: while a condition is True: do something The condition we provide to the while statement is the controlling. While loop favors indefinite iteration, which means we dont specify how many times the loop will run in advance.
#While loop python code
If the user enters the wrong secret word more than 7 times, then the loop will be completely exited. A while statement iterates a block of code till the controlling expression evaluates to True. If the user inputs the correct secret word, the loop is terminated. It is always guaranteed to run at least once, with True, which otherwise creates an infinite loop. The code will run at least one time, asking for user input. If the condition evaluates to True then the loop will run the code within the loop's body.įor example, this loop runs as long as number is less than 10: number = 0 Both of them achieve very similar results, and can almost. It will keep executing the desired set of code statements until that condition is no longer True.Ī while loop will always first check the condition before running. The two distinctive loops we have in Python 3 logic are the for loop and the while loop. The general syntax of a while loop in Python looks like this: while condition:Ī while loop will run a piece of code while a condition is True.

Let's focus on how you can create a while loop in Python and how it works. There are two types of loops built into Python: Let's learn more about how loops work in Python.

Loops are a set of instructions that run repeatedly until a condition is met. If you want to automate a specific repetitive task or prevent yourself from writing repetitive code in your programs, using a loop is the best option for that. Loops are a useful and frequently used feature in all modern programming languages.
