Could someone provide an example of how to use the python reference implementation for generating a bech32 address?
For example, generating a mainnet bech32 address for this scriptPubKey: "0014751e76e8199196d454941c45d1b3a323f1433bd6"
The reference implementation provides a handy all-in-one encode function. To encode the scriptPubKey 0014751e76e8199196d454941c45d1b3a323f1433bd6 as a mainnet bech32 address, you would do:
import bech32
import binascii
spk = binascii.unhexlify('0014751e76e8199196d454941c45d1b3a323f1433bd6')
version = spk[0] - 0x50 if spk[0] else 0
program = spk[2:]
print(bech32.encode('bc', version, program)) To add to Andrew's answer I recently used the above code snippet to generate bech32m addresses from P2TR scriptPubKeys.
I cloned the bech32 repo and then created a file for the code snippet in the bech/ref/python directory.
I took a P2TR scriptPubKey from the BIP 341 test vectors e.g. 5120712447206d7a5238acc7ff53fbe94a3b64539ad291c7cdbc490b7577e4b17df5
Then this slightly adjusted code generated the associated bech32m address (bc1pwyjywgrd0ffr3tx8laflh6228dj98xkjj8rum0zfpd6h0e930h6saqxrrm).
import segwit_addr
import binascii
spk = binascii.unhexlify('5120712447206d7a5238acc7ff53fbe94a3b64539ad291c7cdbc490b7577e4b17df5')
version = spk[0] - 0x50 if spk[0] else 0
program = spk[2:]
print(segwit_addr.encode('bc', version, program))
