I install pip install pycryptodome on Python 3.7.2. I'm getting above exception for obj = AES.new(key, AES.MODE_CBC, iv) line. my code is:

from Crypto import Random
from Crypto.Cipher import AES
import random

def get_encryption():
 try:
 str = "This is input string"

 key = b'abcdefghijklmnop' 
 iv = Random.new().read(AES.block_size)

 obj = AES.new(key, AES.MODE_CBC, iv)
 encrypted = obj.encrypt(str)
 print(encrypted)
 except Exception as e:
 print(e)

I tried to all the way but not getting how to solve it.

After tried all the way I got solution. I converted key string into bytes.
code is:

from Crypto import Random
from Crypto.Cipher import AES
import random

def get_encryption():
 try:
 strmsg = "This is input string"

 key = 'abcdefghijklmnop' 
 key1 = str.encode(key)

 iv = Random.new().read(AES.block_size)

 obj = AES.new(key1, AES.MODE_CBC, iv)
 encrypted = obj.encrypt(str.encode(strmsg))
 print(encrypted)
 except Exception as e:
 print(e)
