My python code works in VSCode. On Codewars I get an Exit Code: 137, Max Buffer Size Reached (1.5 MiB). Removing the print() used for debug did the trick.

Thank you benjaminzwhite,
i'm wondering why greet(Paul) does work on codewars.
This kata troubles me.

why does the answer work on codewars but not on my computer (i'm using VSC with python 3.10.9 and jupyter Notebook) ?
For example:
greet(Paul)
gives me an error:

NameError Traceback (most recent call last)
Cell In [10], line 1
----> 1 greet(Paul)

NameError: name 'Paul' is not defined

But: greet('Paul') works well
