Is there any Python package which will allow me to verify if the checksum of a bip39 mnemonic is valid? For instance, I have a 24-word bip39 mnemonic, and I might have made a mistake for one of the words. I want to see which words will result in a valid checksum.

I've seen javscript versions, but nothing in Python

Clone/download this code from Trezor (don't forget the word list).

Then check your word-list like this:

from mnemonic import Mnemonic

code = "word1 word2 [...] word23 word24"
mnemo = Mnemonic("english")
isValid = mnemo.check(code) # returns a boolean
print('Checksum is valid: ' + str(isValid))
