entropy to mnemonic converter

Question

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

As stated by RedGrittyBlock this is really more of a web development question vs a bitcoin one. Also although it can be fun to create keys from file sources, typically it's a bad idea and should be more of a learning exercise than for actual use. To that end you should look at the built-in FileReader() API if you are seeking a simple javascript solution.

For example if you were doing a drag-drop to capture the file

holder.ondrop = function(event) {
  event.preventDefault();

  var file = event.dataTransfer.files[0];
  var reader = new FileReader();

  reader.onload = function(event) { 
    var binary = event.target.result;
    
    //Do whatever you want with the data, sha256 hash it, etc
    
    //var mnemonic = bip39.entropyToMnemonic(binary);
   
  };

  reader.readAsBinaryString(file);
};
