Jan 29, 2009 · Changing the index variable i from within the loop is unlikely to do what you expect. You may need to use a while loop instead, and control the incrementing of the loop variable yourself. Each time around the for loop, i is reassigned with the next value from range(). So something like: if(something): do something. else: do something else.

Sep 13, 2010 · If you're talking about starting over from the beginning of the for loop, there's no way to do that except "manually", for example by wrapping it in a while loop: should_restart = False. for i in xrange(10): print i. if i == 5: should_restart = True. break.

Sep 30, 2023 · In this case, we need the help of a while loop to restart a for loop in Python. The while loop will be executed as an outer loop and the for loop as an inner loop. Here, while the loop will handle everything, it will start the loop or stop the execution.

Jan 10, 2014 · How can I do this in python: x = [1,2,3,4,5,6] for i in x: if i == 4: -restart the loop from beginning- else: print i So here it will print till 4 then repeat the loop

Apr 13, 2024 · To restart a loop in Python: Use a while loop to iterate for as long as a condition is met. In the while loop check if another condition is met. If the condition isn't met, restart the while loop by resetting the variable to its initial value. num += 1 . a_list.append(num) else: .

Depending on the type of loop, there are numerous ways to restart it in Python. In this post, we’ll go over these methods in depth and show you how to use them in your code using real examples. Solutions and Examples

You'll learn how to restart a loop's iteration, skip specific iterations, and exit loops prematurely, using continue, break, and conditional logic within while and for loops. We'll also cover common patterns like looping until a list is empty.

Sep 23, 2021 · The following code shows how to do this in Python: restart = True while restart: for i in range(3): print('i =', i) # loop body # Default: execute once restart = False # Restart loop logic (any restart condition): if input() == 'r': restart = True break # force restart

Feb 26, 2025 · Learn how to restart a loop in Python effectively with various methods including the use of continue statements, while loops, and encapsulating loops in functions. This guide provides clear examples and explanations to enhance your …

There are multiple ways to restart a Python program, each suitable for different scenarios. Let’s explore these approaches. Using Loops for Simple Restarts. Loops offer a straightforward way to restart sections of a program. A while True loop, for instance, can keep retrying a task until a specific condition is met. Practical Example:
