title: How to convert to Python list comprehension
body: <pre><code>ls = ['abc', 56, 49, 63, 66, 80]
  for i in ls:
      if(isinstance(i, int) or isinstance(i, float)):
          for i in range(len(ls)):
              ls[i] = str(ls[i])
  </code></pre>
  
  <p>May I know how to create the list comprehension of above code?</p>
  
  <p>I am trying  the following but not working</p>
  
  <pre><code>if (s for s in ls isinstance(s, int) or isinstance(s, float)):
      for i in range(len(ls)):
          ls[i] = str(ls[i])
  </code></pre>
