What's the difference between the itertool takewhile and the filter module? They seem to be the same thing

filter scans the whole iterator for elements matching the condition. itertools.takewhile stops the moment it finds an element that doesn't fit the condition. Demo code: from itertools import takewhile my_list = [1, -2, 3, -4, 5, -6] print(list(takewhile(lambda x: x>0, my_list))) # outputs [1] print(list(filter(lambda x: x>0, my_list))) # outputs [1, 3, 5]

You're very welcome, Vlad Cretu ! 😊 I saw that you've only been here a week. You're a fast learner! Good for you 👌

Aaaa, ok I understand now. Thank you :)
