[Tutor] Sun Location System

[Carlos]

Hi Again,

I have been working in a sun location system and it seems like is 
working now. But I have two issues that I hope you can help me solve.

I have a number of functions in this script and I would like to know 
which is the best way to pass values among them? Here is the script so far:

#####################################################################
from math import *

# I would like to substitute Lat for the location name
def Sol_Pos (Lat, Month, Day, Hour):

    month_index = Month -1
    date_index = Day -1

    def J_Day(month_index,date_index):
        j_day=0
        date_val=date_index+1
        if (month_index==0):
            j_day = 0+date_val
        elif (month_index==1):
            j_day=31+date_val
        elif (month_index==2):
            j_day=59+date_val
        elif (month_index==3):
            j_day=90+date_val
        elif (month_index==4):
            j_day=120+date_val
        elif (month_index==5):
            j_day=151+date_val
        elif (month_index==6):
            j_day=181+date_val
        elif (month_index==7):
            j_day=212+date_val
        elif (month_index==8):
            j_day=243+date_val
        elif (month_index==9):
            j_day=273+date_val
        elif (month_index==10):
            j_day=304+date_val
        elif (month_index==11):
            j_day=334+date_val
        return j_day
    
 
    def Dec(J_Day):

        Dec = 23.45 * sin(radians(( j_day + 284.0) * 360/365))
        return Dec

    def H_Ang(Hour):

        Hour_Angle = 15*(12-Hour)
        return Hour_Angle

    def Alt(Lat, Dec, H_Ang):

        lat_r     = radians(Lat)
        decl_r     = radians(Dec)
        hour_r  = radians(H_Ang)

        sin_alt_r = 
cos(lat_r)*cos(decl_r)*cos(hour_r)+sin(lat_r)*sin(decl_r)
        sin2alt   = sin_alt_r * sin_alt_r
        cos_alt_r = sqrt(1 - sin2alt)

        Alt = degrees(atan(sin_alt_r / cos_alt_r))
        return Sol_Alt

   def Az(Lat, Dec, H_Ang):

        lat_R = radians(Lat)
        decl_R = radians(Dec)
        hour_R = radians(H_Ang)

        x_azm = sin(hour_R) * cos(decl_R)
        y_azm = (-(cos(hour_R))*cos(decl_R)*sin(lat_R))+(cos(lat_R)* 
sin(decl_R))

        if Lat > 0:
                y_azm = y_azm * -1
               
        Azimuth = degrees(atan2(x_azm, y_azm)) 
        return Azimuth

And my idea is to give the script a location name, date and hour and it 
will return the sun position relative to that info. So how can I work 
with info of this type?

30.30 48.20 Abadan, Iran
45.40 -98.40 Aberdeen Ap, South Dakota - USA
57.10 -2.10 Aberdeen, Scotland
46.90 -123.80 Aberdeen, Washington - USA
5.30 -4.00 Abidjan, Ivory Coasti
32.40 -99.60 Abilene Ap, Texas - USA
5.50 -0.20 Accra, Ghana

I know that a dictionary probably is a solution, but as you can imagine 
formatting this data is going to take a long time, there are too many 
locations. Is there a solution for this problem?

Thanks for your help,
Carlos
