There is no `get` method to the `list` type.
Maybe you'd like the following:
```
argv_dict = dict(enumerate(argv))
host = argv_dict.get(1)
username = argv_dict.get(2)
password = argv_dict.get(3)
if host is None:
host = get_input("Host (ex: http://localhost:8008 ): ")
if username is None:
username = get_input("Username: ")
if password is None:
password = getpass() # Hide user input
```

IMO, list.get() is superior to either method.

This looks like marginal readability improvement to me. Sign-off per contributing.rst, and I can merge. |
