Question

I am writing a module, in which the email string is validated before it gets inserted into the db. When i try to enter invalid email string it prints else block with wrong email message but when i enter the correct email string it doesnt do anything. Here is the code:

   #!/usr/bin/python

import MySQLdb
import re
# Open database connection
db = MySQLdb.connect("localhost","root","root","acl" )

# prepare a cursor object using cursor() method
cursor = db.cursor()

def addUser(email,password):
    
    try:
        if validateEmail(email):
            sql = "INSERT INTO acl_users(email, password) VALUES ('%s', '%s')" % (email, password)
                # Execute the SQL command
            cursor.execute(sql)
                # Commit your changes in the database
            db.commit()
        else:
            print "wrong email"
    except Exception as inst:
 # Rollback in case there is any error
    db.rollback()
    print inst

def validateEmail(email):

    if len(email) > 7:
        if re.match("^.+\\@(\\[?)[a-zA-Z0-9\\-\\.]+\\.([a-zA-Z]{2,3}|[0-9]{1,3})(\\]?)$", email) != None:
            return True
        else:
            return False
    else:
        return False

Any suggestions please?

got the answer guys! after creating instance of the exception in except block i got to know that import re was missing. that solved the problem.

Answer 1

in validateEmail you use the module re, but you did not import it.
