Feature or enhancement

Proposal:

Same as I did for get_close_matches in #142939.

There is one more instance of this, where ratio is calculated twice.

if (crqr() > best_ratio
      and cqr() > best_ratio
      and cr() > best_ratio):
    best_i, best_j, best_ratio = i, j, cr()

Has this already been discussed elsewhere?
