A concrete starting point
Enumerate combinations of ordered product options only after checking the result limit. Test an empty group and duplicate option labels, rejecting excess combinations before allocating the output.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.

A concrete starting point
from itertools import product

def variants(groups, limit):
if type(limit) is not int or limit < 0:
raise ValueError("limit")
if not groups: return []
if any(len(set(g)) != len(g) for g in groups):
raise ValueError("duplicate option")
if prod(map(len, groups)) > limit:
raise ValueError("too many variants")
return list(product(*groups))The example is a starting point for a real project, not a claim that generated code is already tested. Adjust paths, dependencies and expected behavior to match your application.
