pycrypto AES passphrase greater than block size

I have a quick question with reference to pycrypto AES encryption. Suppose I use the accepted answer to the Encrypt & Decrypt using PyCrypto AES 256, and I have my passphrase to AES encryptor > 16 bytes(my block size), will the data be truncated or will it still be encrypted. Please shed some light. Thank you.

I’m not sure, but you should not use the password directly as input to AES. Instead, run your password through a key derivation function like scrypt, bcrypt, or PBKDF2 and use that as your AES key. See my comment regarding KDFs.
