How do I call a specific python function in a file from the command line? [duplicate]

Question

Say there is the following function in a file called fb_auth_token.py

def get_fb_access_token(email, password):
...
return ...

How would I run this from bash? python fb_auth_token.py get_fb_access?. How do I call just the one specific function?

Answer 1

You could either call python with the command option:

python -c "from file_name import function;function()"

or if you want this function to be called every time you execute the script you could add the line

if __name__ == "__main__":
    function()

This will then only execute this function if the file is executed directly (i.e. you can still import it into another script without "function" being called).

Answer 2

I figured it out:

python -c 'import fb_auth_token; print fb_auth_token.get_fb_access_token("email", "password")'
