Transcript

[in a yellow box:]
Whenever I learn a new skill I concoct elaborate fantasy scenarios where it lets me save the day.

Megan: Oh no! The killer must have followed her on vacation!
[Megan points to computer.]
Megan: But to find them we'd have to search through 200 MB of emails looking for something formatted like an address!
Cueball: It's hopeless!

Off-panel voice: Everybody stand back.

Off-panel voice: I know regular expressions.

[A man swings in on a rope, toward the computer.]

tap tap
The word PERL! appears in a bubble.

[The man swings away, and the other characters cheer.]

I guess I'm just not sure what your doing in Python that is equivalent in some way to regex without using the re library. Like, do you mean you're using looped ifs and raw strings to do something similar?
