Kerykeion
Kerykeion is a python library for Astrology. It can calculate all the planet and house position, also it can calculate the aspects of a single persone or between two, you can set how many planets you need in the settings in the utility module. It also can generate an SVG of a birthchart, a synastry chart or a transit chart.
Here's an example of a birthchart:
Web API
If you want to use Kerykeion in a web application, I've created a web API for this purpose, you can find it here:
It's open source, it's a way to support me and the project.
Donate
Maintaining this project is a lot of work, the Astrologer API doesn't nearly cover the costs of a software engineer working on this project full time. I do this because I love it, but until I can make this my full time job, I won't be able to spend as much time on it.

Installation
Kerykeion is a Python 3.9 package, make sure you have Python 3.9 or above installed on your system.
pip3 install kerykeionUsage
Here some examples:
# Import the main class for creating a kerykeion instance:
from kerykeion import AstrologicalSubject
# Create a kerykeion instance:
# Args: Name, year, month, day, hour, minuts, city, nation(optional)
kanye = AstrologicalSubject("Kanye", 1977, 6, 8, 8, 45, "Atlanta")
# Get the information about the sun in the chart:
# (The position of the planets always starts at 0)
kanye.sun
#> {'name': 'Sun', 'quality': 'Mutable', 'element': 'Air', 'sign': 'Gem', 'sign_num': 2, 'pos': 17.598992059774275, 'abs_pos': 77.59899205977428, 'emoji': '♊️', 'house': '12th House', 'retrograde': False}
# Get information about the first house:
kanye.first_house
#> {'name': 'First_House', 'quality': 'Cardinal', 'element': 'Water', 'sign': 'Can', 'sign_num': 3, 'pos': 17.995779673209114, 'abs_pos': 107.99577967320911, 'emoji': '♋️'}
# Get element of the moon sign:
kanye.moon.element
#> 'Water'To avoid connecting to GeoNames (eg. avoiding hourly limit or no internet connection) you should instance kerykeion like this:
kanye = AstrologicalSubject(
"Kanye", 1977, 6, 8, 8, 45, lng=50, lat=50, tz_str="Europe/Rome", city="Rome"
)The difference is that you have to pass the longitude, latitude and the timezone string, instead of the city and nation. If you omit the nation, it will be set to "GB" by default, but the value is not used for calculations. It's better to set it to the correct value though.
Generate a SVG Chart:
from kerykeion import AstrologicalSubject, KerykeionChartSVG
first = AstrologicalSubject("Jack", 1990, 6, 15, 15, 15, "Roma")
second = AstrologicalSubject("Jane", 1991, 10, 25, 21, 00, "Roma")
# Set the type, it can be Natal, Synastry or Transit
name = KerykeionChartSVG(first, chart_type="Synastry", second_obj=second)
name.makeSVG()
print(len(name.aspects_list))
#> Generating kerykeion object for Jack...
#> Generating kerykeion object for Jane...
#> Jack birth location: Roma, 41.89193, 12.51133
#> SVG Generated Correctly
#> 38
Report
To print a report of all the data:
from kerykeion import Report, AstrologicalSubject
kanye = AstrologicalSubject("Kanye", 1977, 6, 8, 8, 45, "Atlanta")
report = Report(kanye)
report.print_report()Returns:

Most of the functions and the classes are self documented by the types and have docstrings. An auto-generated documentation is available here.
Sooner or later I'll try to write an extensive documentation.
