here's my code !

from mysql import connector
con = connector.Connect(user='root',password='root',database='test',host='localhost')

note i've used this query also ! :

"""insert into user ( username , password ) values ('userName', 'passWord');"""

and tried so many ways , but nothing happend (not inserted and no exceptions throwed either !)

Answer 1

from mysql import connector
con = connector.Connect(user='root',password='root',database='test',host='localhost')
cur=con.cursor()
cur.execute("""insert into user values ('userName', 'passWord')""")
**con.commit()**
con.close()

You probably forget to use con.commit, to commit your changes to database.

Don't use con.commit() for for each INSERT/UPDATE operation, use it for group of operations, that logical combines by SQL rules
