Unexpected infinite loop when processing a list with a specific pattern in Python

python loops list-comprehension infinite-loop Python

I'm wondering if anyone has experience with I'm trying to configure I've encountered a strange issue with I'm trying to implement Quick question that's been bugging me - This might be a silly question, but I'm working with an infinite loop scenario when trying to process a list of integers in Python... My goal is to iterate through the list and remove any number that is a multiple of 3, but I accidentally created a situation where the loop never terminates. Here’s the code I wrote: ```python numbers = [1, 3, 5, 6, 9, 10] index = 0 while index < len(numbers): if numbers[index] % 3 == 0: numbers.remove(numbers[index]) else: index += 1 ``` When I run this code, I expected it to output a list without the multiples of 3, like this: `[1, 5, 10]`. However, it seems to enter an infinite loop, and I need to figure out why. The `index` variable isn't being incremented when I remove a number, which I suspect is the question, but I'm not sure how to fix it without running into index errors. I've also tried using a `for` loop instead, but it results in a similar scenario. I came across the suggestion to create a new list instead of modifying the list in place to prevent this behavior, but I'm looking for a solution that allows me to use the same list. Could anyone guide to understand why this is happening and how I can adjust my loop to avoid the infinite loop scenario? I'm using Python 3.9.1, and any help would be greatly appreciated! Am I missing something obvious? My development environment is Windows. Is there a better approach? Could this be a known issue? Has anyone dealt with something similar? I'm working with Python in a Docker container on macOS. Any help would be greatly appreciated!
