Ever wondered what happens when you try to remove elements from a list while iterating over it? Brace yourself for some surprising results as we dive into the intriguing behavior of modifying a list during a loop! Let's unravel the mystery and understand what's really happening behind the scenes.
You may already ware that remove method takes an argument that represents the element to be removed from the list.
We are modifying the list while iterate over it. That means that the first time through the loop, index == 1, so 1 is removed from the list. Then the for loop goes to the second item in the list, which is not 2, but 3! Then that's removed from the list, and then the for loop goes on to the third item in the list, which is now 5. And so on.
