python built-in function to do matrix reduction

Question

Does python have a built-in function that converts a matrix into row echelon form (also known as upper triangular)?

Answer 1

Basically: don't do it.

The rref algorithm produces too much inaccuracy when implemented on a computer. So you either want to solve the problem in another way, or use symbolics like @aix suggested.
