title: Assign each value from one list to another with different number of indexes
body: <p>I want to assign each letter from list letters to each number from list numbers, but they have different indexes so when x grows above 4 error appears. How to solve this?</p>
  <pre><code>letters = [&quot;A&quot;, &quot;B&quot;, &quot;C&quot;, &quot;D&quot;]
  numbers = [&quot;1&quot;, &quot;2&quot;, &quot;3&quot;, &quot;4&quot;, &quot;5&quot;]
  x = 0
  y = 0
  for i in #?:
  
      print(letters[x] + numbers[y])
      if x &lt; 4:
          x += 1
          y += 1
      elif x == 4:
          y += 1 
  </code></pre>
  <p>I want my output to be:</p>
  <pre><code>A1
  A2
  A3
  A4
  A5
  B1
  etc.
