Why doesn't this function work?

This is the goal: “This function repeatedly removes the first element of a list until it finds an odd number or runs out of elements. It will accept a list of numbers as an input parameter and return the modified list where any even numbers at the beginning of the list are removed.”

Can someone please explain why this function does not work?
If the image did not show up, this was my solution:
def delete_starting_evens(lst):
for num in lst:
if num % 2 == 0:
return lst

When I printed these:
print(delete_starting_evens([4, 8, 10, 11, 12, 15]))
print(delete_starting_evens([4, 8, 10, 12, 15]))

The output was:
[11, 12, 15]
[10, 12, 15]

It’s problem number 3 on this page

list.pop(0) always removes whatever the first item in the list is, which may not be the item that you’re currently dealing with. You may want to look up .remove (but trying to remove an element from a list while iterating through it may not work the way you’d expect).
Iterating through the list using the indices may work better.
