Package: immanuel
Immanuel is a Python >= 3.10 package to painlessly provide your application with simple yet detailed chart-centric astrology data for planets, points, signs, houses, aspects, weightings, etc. all based on theSwiss Ephemeris. Extra calculations, notably secondary progressions and dignity scores, are modeled on those ofastro.comandAstro Gold.Data for natal charts, solar returns, progressions, and composites are available, as well as the ability to point the aspects from any one chart instance to the planets in another, creating a flexible method to build synastries.Simply pass in a date and coordinates to one of the available chart classes, and the returned instance will contain all data necessary to construct a full astrological chart. A serializer is bundled to easily output all data as JSON, or it can simply be printed out as human-readable text.DocumentationFull documentation is availablehere, or follow the Quick Start below to see how to quickly generate a natal chart.Quick StartYou can get started with full natal chart data in minutes. Simply install Immanuel:pipinstallimmanuelOnce you've imported Immanuel's chart classes into your application, you will need to hand them a person or event. This is made easy with the Subject class, which takes a date and geographical coordinates. The date can be an ISO-formatted string or a Python datetime instance, and coordinates can be strings or decimals.fromimmanuelimportchartsnative=charts.Subject(date_time='2000-01-01 10:00',latitude='32n43',longitude='117w09')natal=charts.Natal(native)forobjectinnatal.objects.values():print(object)This will output all the chart objects (planets, points, asteroids etc.) in this format:Sun 10°37'26" in Capricorn, 11th House

This way synastry (and transit) charts can be generated with great flexibility.Returned Chart DataThe various chart types return their own sets of data, but you can expect to receive at least the following in all of them:Chart dateChart coordinatesHouse systemChart shape type (eg. bowl, splash etc.)Whether the chart is diurnal (ie. daytime)Moon phaseAll chart objects (eg. planets, asteroids, primary angles etc.) and their positions & dignities if applicableHousesAspectsWeightings (ie. which objects are in which elements / modalities etc.)All properties are available in both human-readable and JSON format as demonstrated above.CalculationsImmanuel offers the same three methods for MC progression as astro.com, and will produce the same progressed date, sidereal time, and house positions.Planetary dignity scores are based on those of Astro Gold, although these are somewhat flexible via the settings.SettingsThe full documentation covers settings in detail, but much of the output can be customized. The settings class allows you to specify and personalize:The house system to useWhat data each chart returnsWhat planets, points, asteroid etc. to includeDetails of the aspect calculationsWhich dignities to use and their scoresThe progression method to use for secondary progressions...and much more.TestsTests are available via pytest.
