<s>[INST] Python: Run function from the command line I have below code in my file:
def hello():
    return 'Hi :)'

How would I run this from the command line?
 [/INST] With the -c (command) argument (assuming your file is named foo.py):
$ python -c 'import foo; print foo.hello()'

Alternatively, if you don't care about namespace pollution:
$ python -c 'from foo import *; print hello()'

And the middle ground:
$ python -c 'from foo import hello; print hello()'
