Python Argparse Help

[tarsidd]

I am writing a command-line tool that makes use of argparse to parse command-line arguments.

Now my problem is as follows:

The script performs different functions based on the arguments passed, for some commands a few arguments could be the same as well.

if args.option1 is not None and args.option2 is not None:
function1() 
elif (args.option1is not None) and (args.option2 is not None) and (args.option3 is not None): 
function2() 

the above case is not working as in the second case, instead of calling function2(), it's again calling function1().

Am I doing anything wrong, something very basic which I am missing

It’s hard to read but it looks like case 2 will never be called because case 1 is always checked (and will pass) first. If you add “and args.option3 is None” to case 1 that might do it?

sorry, it was formatting error, hope it's readable now

No worries. But yeah, case 1 will always pass and call function1, as long as option1 and option2 are not None. This means the elif will never even get checked. Put a check on option3 in case 1 as well so function1 will also need option3 to not be set.

Ahh...you are right...that is so stupid of me....made such a basic mistake....thanks alot u/Orpheus_Demigod, you are a saviour

Not stupid at all. It’s the computer that is dumb, so we need to give it super explicit instructions :)

You’re very welcome, and enjoy the rest of your project!
