Limiting scope of Python import

Question

I have some code that looks like this:

from pyparsing import Word, alphas, Optional, ...
# Do stuff ...
# And at the end, save a result to the outside world.         


        

Answer 1

One easy way is to use function scope to control import visibility within a file:

def prepare_parser():
    from pyparsing import Word, alphas, Optional, ...
    # do stuff, and get the final thing to return
    return ...

parser = prepare_parser()
