The provided code has a good foundation for calculating planetary positions based on birth details. However, there are two key areas that need improvement to achieve accurate results:
1. Lagna Calculation:
The current code uses a placeholder function calculate_lagna that raises a NotImplementedError. Lagna, also known as the ascendant, is a crucial element in Vedic astrology. Calculating it accurately requires a complex astrological algorithm. Here are two options:
* Astrology Library: Consider using a dedicated astrology library like pyjyotish or vedicastro that can handle lagna calculation based on birth details and location.
* External Service: Alternatively, you might explore APIs or web services provided by astrology websites that offer lagna calculation functionality.
2. House Positions:
Similar to lagna, the assign_planets_to_houses function is a placeholder. Determining house positions involves assigning planets to specific astrological houses based on the lagna and birth details. Again, you have two options:
* Astrology Library: Use the same library you choose for lagna calculation. These libraries often handle house assignment as well.
* Manual Implementation: If you don't want to use a library, you'll need to implement the complex astrological rules for assigning planets to houses based on lagna. This requires in-depth knowledge of Vedic astrology.
Here's an improved code structure assuming you choose an astrology library like pyjyotish:
from astral import LocationInfo
from astral.sun import sun
import datetime
from pyjyotish import HouseSystem, pyjyotish
# Function to calculate and return planetary positions
def calculate_planetary_positions(birth_date_str, birth_time_str, place_of_birth):
"""
Calculates planetary positions based on birth details.
"""
try:
birth_date = datetime.datetime.strptime(birth_date_str, "%Y-%m-%d").date()
birth_time_obj = datetime.datetime.strptime(birth_time_str, "%I:%M %p")
birth_datetime = datetime.datetime.combine(birth_date, birth_time_obj.time())
# Geolocation (replace with actual latitude/longitude)
latitude, longitude = 14.4667, 79.3333 # Approximate coordinates - NEEDS PRECISION
# Create pyjyotish object with birth details and location
birth_place = pyjyotish.Geo(lon=longitude, lat=latitude)
birth_details = pyjyotish.Hora(year=birth_datetime.year, month=birth_datetime.month, day=birth_datetime.day,
hour=birth_datetime.hour, minute=birth_datetime.minute, second=birth_datetime.second, tz='UTC')
# Calculate planetary positions using pyjyotish
planets = pyjyotish.Planet(lang=' संस्कृत ') # Use appropriate language for planet names
planetary_positions = {planet.name: planets.get_horoscope_lon(birth_details, birth_place) for planet in planets}
# Calculate lagna using pyjyotish
lagna = pyjyotish.HouseSystem(birth_details, birth_place).get_lagna()[0]
house_system = HouseSystem(birth_details, birth_place, lagna_type='Sripada') # Choose appropriate house system
# Calculate house positions using pyjyotish house system
house_positions = house_system.get_houses_lon()
return {'lagna': lagna, 'planets': planetary_positions, 'houses': house_positions}
except ValueError as e:
return f"Error parsing input: {e}"
except Exception as e:
return f"An error occurred: {e}"
# Example usage
birth_date = "1972-12-21"
birth_time = "1:30 AM"
place_of_birth = "Jammalamadugu" # Needs latitude/longitude
positions = calculate_planetary_positions(birth_date, birth_time, place_of_birth)
print(positions)
Remember to install the pyjyotish library using pip install pyjyotish. This code retrieves the lagna, planetary positions, and house positions using the chosen library. Make sure to consult the library's documentation for proper usage and configuration.
