[ And another two along similar lines]

The structure that repeats is

for each_curve in a_set.curves:
  for each_point in each_curve:
    each_point.pt[0] = each_point.pt[1] * update_value_for_the_set 

You may go along the lines of

for a_set, update_value in ( (kiertopyora, nopeuskiertopyora),
                             (ensio,nopeusensio),
                             (toisio,nopeustoisio),
                             (vihrea,nopeusvihrea) ):
  for curve in a_set.curves:
    for pt in curve.points:
      pt.pt[1]= pt.pt[0] * update_value


Not knowing the exact structures you have, I removed the temp variables,
which may be useless.    

Keep in mind that python's variables are dynamic references.
