Not just Python either. The very first piece of code I wrote on a Linux
machine was a shell script that (very badly, and even more very slowly)
counted the number of files in a directory. 20 lines (if I remember
correctly) to duplicate a simple:
ls | wc -l
It was a humbling lesson to always check what features a programming
environment or language offers before reinventing the wheel with four
sides.
Thankfully easier in a relatively concise language like Python as
opposed to (say) Java. Which reminds me, in what version of Python are
we getting the singletonMap? :)
