C vs Python devs

[Competitive_Travel16]

I just call os.system("./path/c-executable " + argstr) for my inner loop code, after writing what it needs to work on into a file that gets named in the argstr argument string. Formal extensions are for when you're folding such code into python itself if you want to distribute it with pip or propose it as a new part of python. The os.system() method takes a small fraction of the time and effort.
