title: comparing two lists and finding indices of changes
body: <p>I'm trying to compare two lists and find the position and changed character at that position. For example, these are two lists:</p>
  
  <pre><code>list1 = ['I', 'C', 'A', 'N', 'R', 'U', 'N']
  list2 = ['I', 'K', 'A', 'N', 'R', 'U', 'T']
  </code></pre>
  
  <p>I want to be able to output the position and change for the differences in the two lists. As you can see, a letter can be repeated multiple times at a different index position. This is the code that I have tried, but I can't seem to print out the second location accurately.</p>
  
  <pre><code>for indexing in range(0, len(list1)):
      if list1[indexing] != list2[indexing]:
          dontuseindex = indexing
          poschange = indexing + 1
          changecharacter = list2[indexing]
  for indexingagain in range(dontuseindex + 1, len(list1)):
      if list1[indexingagain] != list2[indexingagain]:
          secondposchange = indexingagain + 1
          secondchangecharacter = list2[indexingagain]
  </code></pre>
  
  <p>Is there a better way to solve this problem or any suggestions to the code I have?</p>
  
  <p>My expected output would be:</p>
  
  <pre><code>2    K
  7    T
  </code></pre>
