I have identical databases in sqlite and postgres. I want to run the
same code against them, but am having a small issue.
Current code below throws the dreaded:
NameError: global name 'db' is not defined
on line 12
How do I fix it? I want to keep dbconnect() as a separate function.
Thanks.

1 import sqlite3, psycopg2
2
3 def dbconnect(dbtype):
4 if dbtype == "sqlite":
5 conn = sqlite3.connect(cstr)
6 elif dbtype == "postgres":
7 conn = psycopg2.connect(cstr)
8 return conn.cursor()
9
10 def updatedb(dbtype):
11 db = dbconnect(dbtype)
12 db.execute("DML code")
13 print "updated " + dbtype
14 'close connection
15 def main():
16 updatedb('sqlite')
17 updatedb('postgres')
18
19 if __name__ == "__main__":
20 main()
