pyprql
pyprql contains:
pyprql.pandas_accessor — Pandas integration for PRQL
pyprql.polars_namespace — Polars integration for PRQL
pyprql.magic — IPython magic for connecting to databases using %%prql
pyprql.compile — An export of prqlc's compile function
For docs, check out the pyprql docs, and the
PRQL Book.
Installation
pip install pyprql
Or, install with optional dependencies:
pip install pyprql[polars]
Usage
Pandas integration
import pandas as pd
import pyprql.pandas_accessor
df = (...)
results_df = df.prql.query("select {age, name, occupation} | filter age > 21")
Polars integration
import polars as pl
import pyprql.polars_namespace
df = (...)
results_df = df.prql.query("select {age, name, occupation} | filter age > 21")
Jupyter Magic
In [1]: %load_ext pyprql.magic
In [2]: %prql postgresql://user:password@localhost:5432/database
In [3]: %%prql
...: from p
...: group categoryID (
...: aggregate {average unitPrice}
...: )
In [4]: %%prql results <<
...: from p
...: aggregate {min unitsInStock, max unitsInStock}
Compilation
This library exposes prqlc.compile, so we can simply generate SQL:
import pyprql
pyprql.compile("from artists | select track")
print(pyprql.compile("from artists | select track"))
...returns...
SELECT
track
FROM
artists
For context, prqlc in Python is the Python binding for the prqlc Rust crate, so only
contains functions for compilation; and this library offers broader python
integrations and tooling.
