python loops list-comprehension Python

I've spent hours debugging this and I'm optimizing some code but I'm trying to implement I just started working with I'm trying to figure out I'm working on a personal project and I'm working with an scenario when trying to modify a list while iterating over it in Python 3.9......... I have a list of integers and I want to remove elements that are even while iterating through it. Here’s my code snippet: ```python numbers = [1, 2, 3, 4, 5, 6] for num in numbers: if num % 2 == 0: numbers.remove(num) ``` I expected the output to be `[1, 3, 5]`, but instead, it returns `[1, 3, 5, 6]`. It seems like the loop skips some elements when I remove them. I've read that modifying a list while iterating can lead to unexpected issues, but I thought I could handle it directly. What’s the best practice to achieve what I want without running into these problems? I've also tried alternatives like using a list comprehension, but I prefer the loop for readability in this case. Any suggestions? My development environment is macOS. How would you solve this? Is this even possible? I'm open to any suggestions. I'm using Python 3.10 in this project. What's the best practice here?
