Do you have any suggestions for a new well maintained Bitcoin python library for production use instead of testing?

I'm not a python programmer to be familiar with the libraries and their pros and cons but I've seen bitcoinlib be used in a couple of places and it seems to be actively developed. It also has a doc you could read.
Depending on your use case you may want to look into using Electrum wallet software too. It is written in python and it can handle address creation and much more.

Thanks @pooya87 I have heard about Bitcoinlib and have tested with it in the past. Its not what I am looking for, yes Electrum is good totally agree with that.

pycoin is also quite popular and partially support altcoin as well. The documentation also exist, although i find it's not easy to read.

Thanks @ETFbitcoin I tried pycoin in the past its a really good library, but again its not what I am looking for. I just need a library that can do this specific task it doesn’t need to provide too many things.

There is a helpful blog post at https://matthewdowney.github.io/create-segwit-address.htmlwhich provides the code to generate the P2SH address from a public key with minimal dependencies.

This is the only thing that needs to be installed:

Code:

(base) zenulabidin@artanis:~/Documents$ pip install git+https://github.com/matthewdowney/bip32utils
Collecting git+https://github.com/matthewdowney/bip32utils
Cloning https://github.com/matthewdowney/bip32utils to /tmp/pip-req-build-bqskxgsa
Running command git clone -q https://github.com/matthewdowney/bip32utils /tmp/pip-req-build-bqskxgsa
Requirement already satisfied: ecdsa in /home/zenulabidin/anaconda3/lib/python3.8/site-packages/ecdsa-0.16.1-py3.8.egg (from bip32utils==0.3.post3) (0.16.1)

Then you can run the code in the link:

Code:

import hashlib
def hash160(x): # Both accepts & returns bytes
return hashlib.new('ripemd160', hashlib.sha256(x).digest()).digest()

from bip32utils import Base58

def p2wpkh_in_p2sh_addr(pk, testnet=False):
"""
Compressed public key (hex string) -> p2wpkh nested in p2sh address. 'SegWit address.'
"""
# Script sig is just PUSH(20){hash160(cpk)}
push_20 = bytes.fromhex("0014")
script_sig = push_20 + hash160(bytes.fromhex(pk))

# Address is then prefix + hash160(script_sig)
prefix = b"\xc4" if testnet else b"\x05"
address = Base58.check_encode(prefix + hash160(script_sig))
return address

>>> pub = "03a1af804ac108a8a51782198c2d034b28bf90c8803f5a53f76276fa69a4eae77f"
>>> p2wpkh_in_p2sh_addr(pub)
"36NvZTcMsMowbt78wPzJaHHWaNiyR73Y4g"
>>> p2wpkh_in_p2sh_addr(pub, testnet=True)
"2Mww8dCYPUpKHofjgcXcBCEGmniw9CoaiD2"

I ran the examples above and I was able to reproduce them (there is a small function error in the original post, hash160_bytes should be just hash160).

Thanks @NotATether the code does work Wink

, thats what I was looking for specifically.
