Which python snippet is better?

Question

I've coded the answer to the 'longest word' challenge in two ways. (See my profile, or i can paste it here if its easier)

First came the condensed version, which has a line full of nested functions.
Then I duplicated it and split each function step out using a variable.

Which version would be more efficient, and which is best to use in the real world?

Answer 1

As far as time complexity goes they are about the same O(n). The condensed uses slightly less memory. In reality the difference between the 2 is negligible. So you use the code that is cleaner, easier to read and understand.
