Comma separated inputs instead of space separated inputs for argparse

Question

I'm using argparse to receive inputs from the command line to run my script.

My current input string looks like this:

path> python <\filename\\> -t T1 T2 T3 -f F1 F2

Is there a parameter in argparse such that instead of separating inputs by space, I can separate them by commas?

In other words:

path> python <\filename\\> -t T1,T2,T3 -f F1,F2

Answer 1

There is no such feature in argparse.

Alternatives:

• post-process the args namespace and split/parse the values manually
• define a custom action and split/parse the values manually
• define a custom type and split/parse the values manually
• subclass ArgumentParser and customise ArgumentParser.convert_arg_line_to_args
