entropy to mnemonic converter

how to make an entropy to mnemonic converter
to read a file with an array line by line
in python or javascript
there
var bip39 = require(‘bip39’)

var mnemonic = bip39.entropyToMnemonic(‘00000000000000000000000000000000’)
console.log(mnemonic)
but I can’t figure out how to read from the file
if there is a python easier tell me
