Python is, by far, the language of your choosing when you need to build a toolchain of utilities that interact with local systems, servers, other software, running processes, and generally all things outside of your application development.
I leave out application development because I still believe that when it comes to server-side application code that lives for exactly one user request, the best language is the one you are comfortable with. It may be Python, but it may also be Ruby, PHP, Scala, Erlang, Haskell, or one of those new-age sparkly languages such as Go or Rust.
Yet, as you dig deeper into forking processes, maintaining a running state, cleaning up after yourself (I’m talking about memory, I will assume that you bathe), and generally acting predictably, Python is, without a doubt, your chosen language.
Why? I’ll tell you why.
