Instead of removing items from the list while iterating through it, you can create a new list containing only the elements that don't meet the criteria using list comprehensions. e.g:
Python:
filtered_list = [tup for tup in testlist if not determine(tup)]
This creates a new list called
filtered_list
that consists of the tuples in
testlist
that don't satisfy the determine(tup) condition. This way, you avoid modifying the list while iterating through it, which can lead to unexpected behavior or errors.
