Also, do y'all call main() in the if block or do you just put the code you want to run in the if block?

I use if__name__main__ often when working with AWS Lambda, but I also want to run it locally. Lambda wants to call a function with the params event and context. So I would do something like this:

def handler(event, context):
    things
    return {
        'statusCode': 200,
        'body': 'Hello from Lambda!'
    }

if __name__ == '__main__':
    event = {}
    context = {}
    response = handler(event, context)
    print(response)

isn't that just normal usage? ..or, did I just whoosh and you were sarcastically saying that?

[–] [email protected] 6 points 5 days ago (2 children)

It is normal usage. Though personally I'd probably make another "main" function, to avoid declaring a bunch of global variables

[–] [email protected] 2 points 5 days ago

Yeah. I like using main() that way too. It's usually just a high-level function that handles globals relevant to running in standalone and calling other functions to do work.

People used to think it was normal to beat children. Just because it’s normal doesn’t mean it isn’t diabolical.

oh. I never really thought of myself as diabolical. Since I guess by that definition I am, maybe I should learn Python.
