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?

[–] fruitcantfly@programming.dev 6 points 3 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

[–] nickwitha_k@lemmy.sdf.org 2 points 3 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.
