kerykeion 4.0.2

A python library for astrology.

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:

AstrologerAPI

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.

If you want to support me, you can do it here:

Installation

Kerykeion is a Python 3.9 package, make sure you have Python 3.9 or above installed on your system.

pip3 install kerykeion

Usage

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"
    )

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:

Documentation

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.
