Tips for golfing in Pyth Pyth is a Python-inspired procedural programming language, created by PPCG user isaacg.

What general tips do you have for golfing in Pyth? I'm looking for ideas that can be applied to code golf problems in general that are at least somewhat specific to Pyth.

One tip per answer, please.
Write the code in Python first
Pyth is so similar to Python that it is pretty easy to translate Python programs to Pyth. However, because Pyth is a single-letter-per-command language, it is sometimes hard to write straight Pyth. By writing in Python first, there is less to think about at a time (since Python is a pretty easy language to code in).
