# Make it use the new module:
from mysci.readdata import read_data
from mysci.printing import print_comparison
from mysci.computation import compute_windchill

# refactor to make more flexible, less hard to change
# add a new key with making changes throughout file

# Column names and column indices to read   index 7

# data types for each column
# float is a function pointer here, not a function

# before calling function; zip  compare lists(?)

# initialize
# windchill = []
# for temp, windspeed in zip( data['tempout'], data['windspeed']):
