god — a grammar of data, for Python
One small vocabulary for manipulating tables, spelled the same way in Python, in R, and as plain text. A pipeline is checked whole before any of it runs, so a bad column is reported at the step that names it rather than failing partway through — or worse, not failing.
import pandas as pd
from god import *
sales = pd.read_csv("sales.csv")
sales >> keep(col.region == "West") \
>> summarize(margin = total(col.margin), by = col.product)
The same sentence runs as plain text, byte-for-byte what you would paste into R or into a database:
run("""
sales
then keep where [region] is "West"
then summarize [margin] as total([margin]) by [product]
""")
And when you reach the edge of the vocabulary, it shows you the same pipeline
in a tool you already know — show_as(pipeline, "pandas"), or "polars",
"pyspark", "dplyr", "sql", "spark".
Installing
pip install grammar-of-data
Then import god. The wheel carries its own engine, so there is nothing else
to install.
The manual, live in both languages, is at https://psychometrician.github.io/god-book/.
