EOFError when there isn't main()

[chupocro]

I tried to run the keyboard_example.py example and it works fine but when I removed def main() and if __name__ == "__main__"... there was EOFError. In other words, this:

"""Simple example showing how to get keyboard events."""

from __future__ import print_function

from inputs import get_key

"""Just print out some event infomation when keys are pressed."""
while 1:
    events = get_key()
    if events:
        for event in events:
            print (event.ev_type, event.code, event.state)

results in:

Traceback (most recent call last):

    events = get_key()
