Python - Compare two lists in a comprehension

Question

I'm trying to understand how comprehensions work.

I would like to loop through two lists, and compare each to find differences. If one/or-more word(s) is different, I would like to print this word(s).

I'd like this all in one nice line of code, which is why I'm interested in comprehensions.

Answer 1

Doing it in "one nice line of code" is code golf, and misguided. Make it readable instead.

for a, b in zip(list1, list2):
    if a != b:
       print(a, "is different from", b) 

This is not different in any significant way from this:

[print(a, "is different from", b) for a, b in zip(list1, list2) if a!=b]

Except that the expanded version easier to read and understand than the comprehension.
