I always just do this:
def keyword(s):
if s.isupper():
return '\n'+s+'\t'
else:
return s
sql = "SELECT letter.*,letter1.* FROM letter,letter AS letter1 ORDER
BY letter.n;"
s = sql.split()
pp = ' '.join(map(keyword,s))
print pp
Then insert the pp strings into my source code as shown.
# unjoined tables create a Cartesian Product
#
import sqlite3
con = sqlite3.connect(":memory:")
cur = con.cursor()
cur.executescript("""
create table letter(n);
""")
letters = [('a'),('b'),('c'),('d'),('e'),('f'),('g'),('h')]
cur.executemany("""
INSERT
INTO letter(n)
VALUES (?);
"""
, letters)
cur.execute("""
SELECT letter.*,letter1.*
FROM letter,letter
AS letter1
ORDER
BY letter.n;
""")
cartesian_product = cur.fetchall()
for i in cartesian_product:
print i[0]+i[1],
