The variation in inputs (for Python) causes this Kata to randomly pass or fail solutions due to timeout.
Please fix such that the inputs are representative and can be finished in the time budget.

This kata cannot be updated to Node v14 because of the reduced max string length limit which was reverted from 1GB to 256 MB in V8 version 8.2.6: https://github.com/v8/v8/commit/ea56bf5513d0cbd2a35a9035c5c2996272b8b728
Node v14 uses V8 8.4, before since Node v9 (V8: 6.2.100) the 1GB limit was in place.

languages version are inconsistent:

• I passed in JS
• the same approach in python doesn't pass...

I have attempted the kata multiple times with a blank function to measure the test generation speed. Many times I time out, most times it takes at least 11 seconds, and I've never seen it go below 10.

I doubt this kata is completable in its current form, given the time constraints.

This times out:

def triangle(row):
    return 'B'

Does the python test suite generate within 12s?

python is lacking its sample tests.
