Part 4: Inside Out For Loop. #16

Closed riseriyo closed 10 years ago

riseriyo commented 10 years ago

Definition of list comprehension. A bit confusing with statement, "inside-out for loop".

Suggestion: Explain term differently or add more to what you are defining it is as an 'inside-out for loop".

treyhunner commented 10 years ago

@riseriyo mentioned reversed for loop seems more accurate in the simple case (without an if clause in the comprehension).

Some more ideas:

List comprehensions allow you to take a list, do something with each element, and then output a new list with the changed elements. You can also filter out elements.

List comprehensions take in a list and return a new list with every element changed in some way and/or filtered out of the list. By "list" we really mean "tuple", "string", or anything else that you can loop over.

Going through part 4 now. Just fixed a type in sets description and pushed to master.
