simple AES encryption and decryption

aes_enc_dec.py

from Crypto.Cipher import AES
from Crypto import Random
def encrypt(key,message):
    cipher=AES.new(key,AES.MODE_CFB,iv)
    msg=cipher.encrypt(message)
    print(msg)
    return msg
def decrypt(key,msg):
    dec=AES.new(key,AES.MODE_CFB,iv)
    return dec.decrypt(msg).decode('ascii')
if __name__=='__main__':
    global iv
    iv=Random.new().read(AES.block_size)
    key='wwwhackerdem.com'
    message='You will newer walk alone'
    print(decrypt(key,encrypt(key, message)))

thank you for the code , can you explain how i can encrypts the data while transfer from one database and insert into another database?
example :
select userid,pass,email from user; >>>>> database 1
{i need method to encrypts the data before insert.}
insert into user2 values(userid,pass,email)>>>> database 2

i hope you got my point , thank you
