I have a program which can take in a few different arguments, and depending on what the argument is that is passed, that function is called in the python program. I know how to use sys.arv, and I have used argparse before, however I am not sure how to go about accomplishing the following with argparse..
Possible arguments: func1, func2, func3
Program could be executed with either of the following:
python myprogram func1
python myprogram func2
python myprogram func3
will accept one string, and raise an error if that string is not one of the chocies. The results will be a namespace like
print(args.foo) # 'func1'
Is that what you want?
The subparsers mechanism does the same thing, but also lets you define added arguents that can differ depending on which subparser is given.
