Hello everyone, I am new to Bitcoin, I have a problem and need help, first of all, thank you, the following is my question：
I tried to use the following code to convert the scriptPubKey in the Bitcoin transaction to an address, but why p2sh cannot be converted? Is there a similar python package that can be converted to an address by drinking it directly
def cover_address(script_pub_key):
script_pub_key_str=hashStr(script_pub_key)
if script_pub_key_str[0:4]==b'76a9':
#This is a pubkeyhash
bytes=script_pub_key[2] #number of bytes in the pub_key
try:
assert bytes==20
except:
return None
public_key = script_pub_key[3:3+bytes] #20 bytes
z=b'\00'+public_key
#checksum=sha256(sha256(z))[:4]
#address1=base58.b58encode(z + checksum)
address2=base58.b58encode_check(z) # adds checksum for you
return format(address2.decode())
elif script_pub_key_str[0:2]==b'a9':
#this is a scripthash (pay-to-script address)
bytes=script_pub_key[1] #number of bytes in the pub_key
try:
assert bytes==20
except:
return None
public_key = script_pub_key[2:2+bytes] #20 bytes
z=b'\05'+public_key #used for mainnet
address2=base58.b58encode_check(z)
return address2.decode()
elif script_pub_key_str[0:2]==b'00':
spk = binascii.unhexlify(script_pub_key_str.decode())
version = spk[0] - 0x50 if spk[0] else 0
program = spk[2:]
return bech32.encode('bc', version, program)
else:
#print(script_pub_key_str)
return None
I want to convert the following into an address, but the address cannot be resolved using the above method. What is wrong?
