title: How to do string interpolation in a for loop using the indices of a list in python
body: <p>I have a list and I want to put its elements inside a for loop string like this:</p>
  
  <pre><code>my_list = ["Germany", "England", "Spain", "France"]
  for this in that:
      do stuff
      print(my_list[0]+ some other stuff)
  </code></pre>
  
  <p>The output should be like:</p>
  
  <pre><code>Germany + some other stuff
  England + some other stuff
  Spain + some other stuff
  France + some other stuff
  </code></pre>
  
  <p>How can I loop the indices for string interpolation as well?</p>
  
  <p>Thanks!</p>
  
  <p>Edit: The loop is a bit different. It's more like this:</p>
  
  <pre><code>for foo in bar:
      another_bar = []
      for x, y in foo:
          do stuff
          a = object.method()
          another_bar.append(my_list[0]+a)
  </code></pre>
  
  <p>I need to put the strings of lists into the 2nd layer of nested loop. Can't use zip here.</p>
