Need to fix SyntaxError in cycle try

[Gribouillis]

Line 2 is 219 characters long. It is way too long. A good rule of thumb is that a line should not exceed 70 or 80 characters. In Python, one can achieve this by enclosing long expressions in parentheses, for example

idef function_gam(et, y3, phb, kj, y7):
  ht = (
      kj[0] * et * cos(y3) / sqrt(phb)
      + kj[1] * -et0 * sin(y3) / sqrt(phb)
      + y7 * sqrt(1 / phb) * et0 * sin(y3)
      + funct_labt(y3, kj[1], y7, kj[0])
        * (sqrt(1 / phb) * (
            1 + et * cos(y3) * (1 + et * cos(y3)**2) / phb**2)))
  return ht
 

This line could perhaps be further divided in several lines.
