Using __import__() for the same package multiple times within the same line of code?

  🐍📅 One-line Python solutions for Advent of Code 2022 and 2023.

I know that title is scary. But just like last year, I'm trying to solve as many days of Advent of Code in a single line of Python as I can. Because of this restriction, I'm using __import__('re') so I can use RegEx in my solutions rather than using the import statement (since that would add an additional line). But this means I have multiple instances that look like __import__('re').findall(r'\d', l) within a single line (as seen here). My question is: what is the impact of this? Is it importing the module every time it is called, or is it considered fully imported after the first call and just referenced in future calls? Is there any other/better way of doing this?
