Argument's name shadows keyword in module argparse python

When I try to get argument with flag "--from" from argparse.ArgumentParser.parse_args() an error occurs. IDE says that "from" is import statement and the code is unreachable:

parser = argparse.ArgumentParser(prog='cache_wiki.py',
                                     description='Find shortest path between links')
parser.add_argument('--from', required=True, help='page to start search with')
args = parser.parse_args()
print(args.from)

It is ok with another name:

parser = argparse.ArgumentParser(prog='cache_wiki.py',
                                     description='Find shortest path between links')
parser.add_argument('--f', required=True, help='page to start search with')
args = parser.parse_args()
print(args.f)

but I really need to use flag "--from".

I would ignore the IDE here. True, you cannot use args.from, but that's just a syntactic limitation. You can still access the attribute using, for example, getattr(args, 'from').

You can also override the default destination name so that you can use the option --from, but set a different attribute:

...
parser.add_argument('--from',
                    required=True,
                    dest='from_',
                    help='page to start search with')

args = p.parse_args(['--from', 'foo'])
assert args.from_ == 'foo'
