p21utils.py
This file holds most of the major functions required to convert the basic horoscope into a rich JSON object. Some of the key functions are listed here. The rest can be deduced by looking at the code.
These functions implement, or rather calculate the PAC or Position-Aspect-Conjunct data that is recommended by KNRao in his book, Learn Hindu Astrology Easily.
The longitude of a Graha is converted into the Rashi of the chart where it resides. The logic changes depending on whether we are working with p21.ChartType = 'Rashi' or 'Navamsa'. Parameter x is a tuple consisting of Graha Name and Longitude from list derived from the dictionary p21.GLon.
Creates a dictionary p21.GRashiN that stores the Rashi number for each Graha as determined by the Long2Rashi() function.
Determines and stores the Bhava in list BhavN. For example, BhavN[1] has Rashi Number corresponding to First Bhav and BhavA[2] has the Rashi name corresponding to Second Bhava
Determines the Lord of each Bhava. Determines the Rashi number where each Lord resides. Determines the Rashi name where each Lord resides.
First Determines the Bhava where Each planet resides. Lagna always resides in First Bhava. Then Determines the Bhav where each Lord resides.
