Have I missed unknown pleasures in Python by focusing on R?

A comment on my blog post of last week suggested just that. Reason enough to explore Python a little. Learning another computer language is like learning another human language – it takes time. Often it is helpful to start by translating from the new language back into the old one.

I found a Python script by Ludwig Schwardt that creates a plot like this:

It is only a small Python script, but it illustrated how to:

  • load packages
  • use conditional statements
  • add comments
  • write functions
  • deal with arrays
  • write loops
  • create plots
  • save output into a PDF file

Here is my translation into R, which actually generated the plot above.
