If line#24 use 'wif_compressed', it will produce a wrong Key (WIF-Compressed) started with 2.
So there should be 'wif', unless :
wif_compressed_private_key = bitcoin.encode_privkey(
bitcoin.decode_privkey(private_key, 'hex'), 'wif_compressed')
This is also right.
However, use the 'compressed_private_key' and 'wif_compressed' is wrong.
