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 would put my code in a def main(), so that the local names don't escape into the module scope:
if __name__ == '__main__':
def main():
print('/s')
main()
(I didn't see this one yet here.)
I'm a little new to Python standards. Is this better or worse than putting the def main(): outside the if statement (but calling main() inside it)
I intended this an sarcastic example; I think it's worse than putting the main outside of the branch because of the extra indent-level. It does have an upside that the main() doesn't exist if you try import this as an module.
I thought confusion about indent levels was the whole point of using python
But it feels like main function should not be indented
wait till you see
if __name__ = "__main__":
main()
`Luckily Python is one step ahead:
Python 3.13.3 (main, Apr 22 2025, 00:00:00) [GCC 15.0.1 20250418 (Red Hat 15.0.1-0)] on linux

^^^^^^^^^^^^^^^^^^^^^
SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '='?
yea I also couldnt get the formatting to work right, triple quotes kept turning things into accented letters, so I gave up.
and also := also known as the walrus operator is very fun and sometimes very convenient to use
The if block is where my arg parser goes
Does everyone call the function of the script main? I never use main(), just call the function what the program is supposed to do, this program calculates the IBNR? The function is called calculate_IBNR(), then at the end of the script if name = 'main': calculate_IBNR(test_params) to test de script, then is imported into a tkinter script to be converter to an exe with pyinstaller
All of mine are called do_thing() because after a few days of working on it, the scope creep always means the original name was wrong anyway.
I've always found needing to manually add a class instance parameter (i.e. self) to every object method really weird. And the constructors being named __init__. Not having multiple dispatch is kinda annoying too. Needing to use decorators for class methods, static methods, and abstract classes is also annoying. Now that I think about it, Python kinda sucks (even though it's the language I use the most, lol).
Nah self is quite important. The main part of a method is to access the state of the object. self is just the interface to it.
Guess I just prefer languages that do it this way:
class AClass {
var aProp = 0
fun aMethod() {
aProp++
}
}
Though I suppose confusion and bugs can happen when you do something like:
class AClass {
var aProp = 0
fun aMethod(aProp: Int) {
// `this.aProp` is needed to access the property
}
}
