Python: best practice and securest way to connect to MySQL and execute queries

What is the safest way to run queries on MySQL? I am aware of the dangers involved with MySQL and SQL injection. However, I do not know how I should run my queries to prevent injection on the variables to which other users (webclients) can manipulate. I used to write my own escape function, but apparently this is "not-done". What should I use and how should I use it to query and do inserts safely on a MySQL database through python without risking MySQL injection?
To avoid injections, use execute with %s in place of each variable, then pass the value via a list or tuple as the second parameter of execute. Here is an example from the documentation: c=db.cursor() max_price=5 c.execute("""SELECT spam, eggs, sausage FROM breakfast WHERE price < %s""", (max_price,)) Note that this is using a comma, not % (which would be a direct string substitution, not escaped). Don't do this: c.execute("""SELECT spam, eggs, sausage FROM breakfast WHERE price < %s""" % (max_price,)) In addition, you must not use single quotes around the position holder ('%s') if the parameter is a string as the driver provides these.
