In python using import numpy as np

1. Functions in Python (by hand or by typing) A group of students in a land far far away are writing a function in Python named computeAverageSaturation to compute the average saturation in a core sample. The following choices represent the first lines of the function files written by the students. For each of the choices, identify if it is a valid first line of a function (if they are correct in grammar), and if yes then identify input and output variables (if any) If you claim that the line is not a valid first line of a function, then explain what is wrong with it (a) def computeAverageSaturation): (b) def computeAverageSaturation 2(sat) (c) def computeAverageSaturation.py (sat) (d) def computeAverageSaturation?py (sat): (e) def 3computeAverageSaturation(sat) (f) def computeAverageSaturation(sat) (g) def -computeAverageSaturation(sat) (h) def _computeAverageSaturation (sat) (i) def sat ave computeAverageSaturation (sat, phi) (i) def computeAverageSaturation)
