IIFE Python

Question

Is there an equivalent to an IIFE that I can use in Python?

It would be useful for functions that I am calling immediately.

Answer 1

Idk whether this was qualified as an IIFE but it seems to work in Code Playground : )

print( ( f := lambda x : x ** 2 )(12) )
print( f( 10 ) )

Answer 2

You can write single-line lambda and execute immediately, but this is not exactly the same and has limitations compared to IIFE which can be a block of code of any size.

It would be more pythonic to write an actual real function with def
And then you can put a section at the end of your file to actually invoke any functions or statements, by convention this is usually done in an 'if' block like this

if __name__ == __main__:
execute_anything()
