I did through bash as advised odolvlobo
but it turned out the speed is very low 23 xprv per second and I have a dictionary for 1 million xprv

anyway thank you for checking

If you need better performance, you might want to check different Python library which should have better performance[1-3]. You also could check Python multi-core programming feature[4].

You can make a wrapper script around bip32gen, in a single file using `os.spawnl` to create a bip32gen subprocess and wait for it to exit. The wrapper will just read the list of keys from a file and loop through them.
Note: Make sure you make the script wrapper executable.

Code:

#!/usr/bin/python3
import os

keys = []
file = open('keys.txt' 'r')
for l in file:
keys.append(l.strip('\n'))
for k in keys:
os.spawnl(os.P_WAIT, '/path/to/bip32gen', ['cmd', 'options', 'as', 'list'])

I tried to search and it seems there is no direct guide to making a python script to bulk convert xprv to wif key or hex.

Why not try to play with this python that I found on Github.

- https://github.com/ELHARAKA/MassPrivatekeysToWIF

Just take note only run this offline I do not know if this one is safe I just found it on Google when I search for a guide. Or you can get some idea there and build your own python script,.
