The reason you have the error is because the lists made by glob and os.listdir are not the same, either different files (glob is only getting jpg files and listdir gets everything) or different order, or both.

As others said, you should call sqrt() only with proper values. So better do … #Check discriminant discrim = float((bval**2)-(4*aval*cval)) if float(discrim >= 0): # now it is ok to calculate the roots… root1 = – bval + math.sqrt(discrim) root2 = – bval – math.sqrt(discrim) if float(discrim > 0): print (“Roots at:”, root1, root2) else: … Read more
