conn = micropg.connect(host='127.0.0.1',
                    user='postgres',
                    password='secret',
                    database='database_name',
                    use_ssl=False)
cur = conn.cursor()

cur.execute('select foo, bar from baz')
for r in cur.fetchall():
   print(r[0], r[1])

# execute with parameter
cur.execute('select foo, bar from baz where name=%s ', ['nakagami'])
for r in cur.fetchall():
   print(r[0], r[1])

conn.close()

Restrictions and Unsupported Features

• If installed in Python, it can only handle types supported by MicroPython.
• Supported Authentication METHOD are only 'trust', 'md5' and 'scram-sha-256'.
• Not support for array data types.
• Not support for prepared statements.

If you use md5 authentication METHOD, you may need a patch #2

For CPython

I also wrote a pure Python driver. https://github.com/nakagami/minipg
