UnboundLocalError when accessing location.is_authorised() inside function

When I try:

import location

    def get_direction():
        if location.is_authorized():
        #do something

I get an UnboundLocalError: local variable 'location' referenced before assignment.

But the similar code works with other modules e.g:

import time

    def get_time_diff():
        if time.time() > 1234:
        #do something

How can I get around the UnboundLocalError? Importing the location module inside the function works, but I don't want to have to import it within each function that uses location.

Maybe I'm missing something obvious so any suggestions are appreciated!

Thanks @omz & @Phuket2. my_label.size_to_fit() worked to achieve the alignment I wanted.

When creating a label with the frame attribute set, how can the vertical alignment of text be set within the height of the label? I want the text top aligned not center which appears to be the default.

Thanks!

Something else I can't find details on are the icons used in the widget examples.

E.g. iow:ios7_minus_outline_32

Is there a list of icons we can access?

Thanks, got it. I didn't know about the help feature.

Where do I find documentation on the appex module widget functions?

The page below doesn't cover get_widget_view etc.
