From my research, I've come to know anagram is not case sensitive, but this checkAnagram function is case-sensitive. it's can't pass this test case “Eleven plus two” is an anagram of “Twelve plus one”

Is possible know the mathematical definition of this function?
scipy.special.chndtr
scipy.special.chndtrix

Also this functions:
scipy.special.nctdtr
scipy.special.nctdtrit

Let's make the error message more actionable.

Error user sees:

I would recommend adding similar named column(s):

- $"Provided {columnPurpose} column '{columnName}' not found in training data."
+ $"Provided {columnPurpose} column '{columnName}' not found in training
