How to generate public and private key pairs from the 12 seed words in python

How to generate public and private key pairs from the 12 seed words in python

I basically followed the instructions here How to generate mycelium addresses from the 12 words in python

So my code is similar:

from bip32utils import BIP32Key
from bip32utils import BIP32_HARDEN
from bip32utils import Base58
import os, bip39

strength_bits = 128
entropy = os.urandom(strength_bits // 8)
wallet_generator = bip39.Mnemonic('english')
mnemonic = wallet_generator.to_mnemonic(entropy)
assert wallet_generator.to_entropy(mnemonic) == entropy  # see, bijective!

# Or specify the mnemonic directly if you prefer:
mnemonic = 'aware report movie exile buyer drum poverty supreme gym oppose float elegant'
passphrase = 'test'

seed = bip39.Mnemonic.to_seed(mnemonic, passphrase=passphrase)
key = BIP32Key.fromEntropy(seed)
account_number = 0
i = 0
print key.ChildKey(44 + BIP32_HARDEN) \
         .ChildKey(0 + BIP32_HARDEN) \
         .ChildKey(account_number + BIP32_HARDEN) \
         .ChildKey(0) \
         .ChildKey(i) \
         .Address()

And I verified it using https://iancoleman.io/bip39/#english that the generated address is indeed the first address that this webpage generated as well. However, I also want to get the public and private key pairs using this same library. I originally tried:

print Base58.check_encode(key.ChildKey(44 + BIP32_HARDEN) \
         .ChildKey(0 + BIP32_HARDEN) \
         .ChildKey(account_number + BIP32_HARDEN) \
         .ChildKey(0) \
         .ChildKey(i) \
         .PublicKey())

print Base58.check_encode(key.ChildKey(44 + BIP32_HARDEN) \
         .ChildKey(0 + BIP32_HARDEN) \
         .ChildKey(account_number + BIP32_HARDEN) \
         .ChildKey(0) \
         .ChildKey(i) \
         .PrivateKey())

However, the output of these two calls are not the same as the ones provided by the website above for the same address.

So my question is: what's the proper way for me to generate the public and private key pairs?
