Just keep in mind the following:

3 == 3 == 3
>>> True

# Not equivalent to
(3 == 3) == 3
>>> False

# Equivalent to
3 == 3 and 3 == 3
>>> True

Nice. I've seen the chained comparators with inequalities, but not equalities. Now that I see it, it's obvious that it would work. Just never thought of it before.

Does this map avoid recursion? If so, clever and practical idea!

Indeed that is a common pitfall.
I am surprised noone mentioned it before, thank you!

i did not know about the global variables in python.

your solution is very interesting.

You're welcome ;-)

I had the same problem but it finally worked out. good job lechevalier,thanks, I am learning new things.

same_structure_as([1,'[',']'],['[',']',1]) returns True in Python 3.6 and Python 3.8 - the versions available on CW.
No reason to return anything else in other Python versions.

Hi, the same_structure_as([1,'[',']'],['[',']',1]) results to a False when I use your solution.

Python 3.7.3

Edited

Thanks. That worked.

needs python 3.8

just hit attempt - sample tests are broken for now

Using Python 3.6 I get:

STDERR:
Traceback (most recent call last):
File "main.py", line 3, in
