get sun position based on lat long in python

To get the position of the sun based on a given latitude and longitude, we can make use of the ephem library in Python. First, we need to install the ephem library using pip:

main.py
pip install ephem

Here's an example code snippet that calculates the sun's position based on a given latitude and longitude, for a specific date and time:

main.py
import ephem
import datetime

# set observer's location
observer = ephem.Observer()
observer.lat = '37.7749'  # San Francisco, CA
observer.lon = '-122.4194'
observer.elevation = 10  # meters

# set date and time
date_str = '2022-06-21 12:00:00'  # YYYY-MM-DD HH:mm:ss
date_obj = datetime.datetime.strptime(date_str, '%Y-%m-%d %H:%M:%S')
observer.date = date_obj

# calculate sun's position
sun = ephem.Sun()
sun.compute(observer)

# print sun's altitude and azimuth
print('Sun altitude: {:.2f} deg'.format(sun.alt * 180 / ephem.pi))
print('Sun azimuth: {:.2f} deg'.format(sun.az * 180 / ephem.pi))

In this example, we set the observer's location to San Francisco, CA (lat: 37.7749, long: -122.4194) and the date and time to June 21, 2022 at 12:00:00 noon. The code then calculates the sun's position using the compute method of the Sun object, and prints the results. The output should look something like this:

main.py
Sun altitude: 65.73 deg
Sun azimuth: 158.87 deg

This tells us that at the specified location and time, the sun will be at an altitude of 65.73 degrees (above the horizon) and an azimuth of 158.87 degrees (measured clockwise from north).
