equivalent connection for postgres and sqlite

Question

Is there an equivalent way to connect to a postgres database in a similar way that sqlite connects to a database using python?

For example, in sqlite, a connection will be defined by conn = sqlite3.connect(curruser.dbname). What is the similar connection syntax for postgres?

• alf: Which programming language are you using?

Answer 1

You can use the psycopg connector then, and the connection syntax will be similar, except that you'll need to specify some more information in a connection string:

conn_string = "host='localhost' dbname='my_database' user='postgres' password='secret'"
conn = psycopg2.connect(conn_string)

Here are some examples: Using psycopg2 with PostgreSQL
