Psycospans brings support for Spans to Psycopg2.

PsycopSpans work by wrapping psycopg2's connect() function and set the connection up for handling Spans' range types.

from psycospans import connect

conn = connect("dbname=test")
cur = conn.cursor()

test_range = intrange(1, 10)
cur.execute("SELECT int4range(5, NULL), %s", (test_range,))

other_range, test_range_cmp = cur.fetchone()

test_range == test_range_cmp # True
other_range == intrange(5) # True


Psycospans will only work with PostgreSQL 9.2 or later.


Psycospans exists on PyPI. Note that you must install psycopg2 manually. This is because you may use either psycopg2 or psycopg2-binary.

pip install psycospans psycopg2-binary


For full doumentation please run pydoc psycospans from a shell.
