Unexpected printing (+paging) when using inspect

[drscotthawley]

Seems the behavior is not unique to inspect. It seems that Fire will unexpectedly print even if you just access locals(). This is a side effect I'd love to disable.

Minimal example:

import fire

def my_routine(arg1, arg2):
    return locals()

if __name__ == '__main__':
    vals = fire.Fire(my_routine) # this produces unwanted print statements
    print("vals = ",vals)

Output includes not just the "vals = " line but two additional variable outputs that occur when locals() gets called while using Fire():

arg1: dummy_arg1
arg2: dummy_arg2
vals =  {'arg1': 'dummy_arg1', 'arg2': 'dummy_arg2'}

It's no so much the printing that's the problem per se, it's the fact that it blocks execution and waits for the user to press enter (if it prints more than a page of variables) that's the main problem.

Fire displays the returned object on completion by default. To disable this, you can use:

noprint = lambda _: None
fire.Fire(my_routine, serialize=noprint)

Awesome! Thank you very much!
