For really, really basic things docopt is good. But you tend to re-invent the wheel when you need to do something other than the basic parsing it supports. The click docs have a good section[1] on this: > On top of that docopt is restricted to basic parsing. It does not handle argument dispatching and callback invocation or types. This means there is a lot of code that needs to be written in addition to the basic help page to handle the parsing results. 1. http://click.palletsprojects.com/en/7.x/why/#why-not-docopt-etc http://click.palletsprojects.com/en/7.x/why/#why-not-docopt-...
