How to write a pairwise column comparison function?

You need to write a pairwise column comparison function. (Columns 1000+)
That is, the values of one row are compared in two columns, and if the proportion of identical values exceeds X, then one of the compared columns must be deleted.

All columns are numeric, with NaNs
Strict comparison required. Not

Pandas.Duplicate correlation looks for exact match, so another crutch is needed‍♂️
