For Encryption

  def encrypt(my_key=KEY, my_iv=IV, my_plain_text=PLAIN_TEXT): 

       key = binascii.unhexlify('ce975de9294067470d1684442555767fcb007c5a3b89927714e449c3f66cb2a4')
       iv = binascii.unhexlify('9aaecfcf7e82abb8118d8e567d42ee86')

       padder = PKCS7Padder()
       padded_text = padder.encode(my_plain_text)

      encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128)  # Initialize encryptor
      result = encryptor.encrypt(padded_text)  

     return {
         "plain": my_plain_text,
         "key": binascii.hexlify(key),
         "iv": binascii.hexlify(iv),
         "ciphertext": result
}

You can do this easily by using the library cryptocode. Here is how you install:

pip install cryptocode

Encrypting a message (example code):

import cryptocode

encoded = cryptocode.encrypt("mystring","mypassword")
## And then to decode it:
decoded = cryptocode.decrypt(encoded, "mypassword")
