Is there a python module to solve linear equations?

Question

I want to solve a linear equation with three or more variables. Is there a good library in python to do it?

Answer 1

You can use least square method in python to solve system of equations for example for solving equations 3x+4y=7 and 5x+6y=8

>>> import numpy
>>> a=[[3,4],[5,6]]
>>> b=[7,8]
>>> numpy.linalg.lstsq(a,b)
(array([-5. ,  5.5]), array([], dtype=float64), 2, array([ 9.27110906,  0.21572392]))
