title: convert letter from a list into a number depending on another list in python
body: <p>I want to convert each letter of the list word to a number depending on the lists character and number. So a = 0, b = 02300, c = 2.
  I want this output:</p>
  
  <pre><code>encoding = [34, 9, 432, 432, 104, 124546324, 104693, 104, 432, 5]
  </code></pre>
  
  <p>ps: It's not import if there's no space between each number.</p>
  
  <pre><code>word = ["Hello world"]
      encoding = []
      charachter = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z",""]
      number = [0,02300,2,5,9,7,10,34,876,23,125,432,567,103,104,10234,102435,332,7654,12435,65434,12121,104693,130694,120357,12346,124546324]
  </code></pre>
  
  <p>I don't no what to do because the numbers of the list number are not equal to the index of the letters in the list character. </p>
  
  <p>PS: I hope there's not another topic like this because I didn't find it</p>
