Do Python argparse accept single-character abbreviations for subparents?

Question

I use the excellent subparser argparse system to make a command line program that accepts many different commands. From what I read, argparse automatically accepts single-character abbreviations for arguments when they are unambiguous. I want him to do the same for steamers. If I configured my subparameters as follows:

  foo_parser = subparsers.add_parser('foo') # ... set up arguments and handler ... bar_parser = subparsers.add_parser('bar') # ... set up arguments and handler ... 

Then I would like the analyzer to accept myprogram f arg0 as the unique abbreviation for myprogram foo arg0 . But this is not so.

Any ideas?

It is not clear from the argparse documentation whether it supports such automatic reduction for subparser, but you can explicitly set an alias, like so:

 foo_parser = subparsers.add_parser('foo', aliases=['f']) 

On the other hand, argument reduction is supported .
