I would like to have a optional argument that will default to a value if only the flag is present with no value specified, but store a user-specified value instead of the default if the user specifies a value. Is there already an action available for this?
An example:
python script.py --example
# args.example would equal a default value of 1
python script.py --example 2
# args.example would equal a default value of 2
I can create an action, but wanted to see if there was an existing way to do this.
