How can I get all the addresses associated with my public key with bitcoinlib?

Question

I want to get all the addresses associated with my extended public key. I found how to do this on bitcoinlib's docs:

Initialize an Address object. Specify a public key, redeemscript or a hash.

>>> addr = Address('03715219f51a2681b7642d1e0e35f61e5288ff59b87d275be9eaf1a5f481dcdeb6', encoding='bech32', script_type='p2wsh')
>>> addr.address
'bc1qaehsuffn0stxmugx3z69z9hm6gnjd9qzeqlfv92cpf5adw63x4tsfl7vwl'

However I'm having issues getting Address() function to work, since my code:

from bitcoin import *  # using import * because not sure what else to import?
master = Address("my extended pub key", encoding='bech32', script_type='p2wpkh')
print(master.address)

Produces this error:

NameError: name 'Address' is not defined

Yes, and you say you're having issues, but what does that actually *mean*? Errors? Unexpected outputs? — jonrsharpe, Jan 16 '21 at 22:28
`using import * because not sure what else to import` - presumably you need to import `Address` properly — mkrieger1, Jan 16 '21 at 22:30
That could very well be the issue but I'm not sure what to import, using `bitcoinlib.keys import Address` says `bitcoinlib` isn't a module — fiji, Jan 16 '21 at 22:32
But then, what solved your issue fiji? I added an answer with a generic approach so you can test creating a virtualenv and installing it there. — fedorqui, Jan 16 '21 at 23:15
I uninstalled python3.9 completely so all my programs were forced to use 3.8 which it worked using 3.8 — fiji, Jan 16 '21 at 23:43

If you want to use the bitcoinlib library and check the addresses associated with your extended public key, you should do as follows:

pip install bitcoinlib

After that, using the Python binary where this package was installed, open a Python terminal and say:

from bitcoinlib.keys import Address

Needless to say it is recommendable to use a virtualenv and also that import * is not a very good idea. See the following Q&A to get more details on it:

from bitcoin import *

Using import * is not a good practice. Not only does this import stuff that you don't need and you don't know what exactly it imports, it also does not import what you do need in this case.

According to the documentation you have linked, you need to use this import statement:

from bitcoinlib.keys import Address

I tried that but that gives `ModuleNotFoundError: No module named 'bitcoinlib'` – fiji Jan 16 '21 at 22:33
Did you install the same library for which you have linked the documentation? – mkrieger1 Jan 16 '21 at 22:35
Yes, bitcoinlib. – fiji Jan 16 '21 at 22:36
@fiji `pip install bitcoinlib` and then `from bitcoinlib.keys import Address` worked well to me. – fedorqui Jan 16 '21 at 22:57
Seems very odd, my VSC and PyCharm both used Python 3.9 (where bitcoinlib wouldn't install) rather than Python3.8 which I set my project to use. Alas, it worked. Thank you! – fiji Jan 16 '21 at 23:02
