title: Inconsistent use of spaces and tabs in Python
body: <p>I am trying to print a list of groups in AWS.</p>
  
  <p>Of these lines only one line is producing an indentation error. If I use this code:</p>
  
  <pre><code>group_list = client.list_groups()
  print("Group List for %s:")
  for group in group_list['Groups']:
      group_name = group['GroupName']
      print(group_name)
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>  File ".\aws_iam_utils.py", line 966
      print(group_name)
                      ^
  TabError: inconsistent use of tabs and spaces in indentation
  </code></pre>
  
  <p>But if I remove the line <code>print(group_name)</code> the program runs.</p>
  
  <p>I tried both adding that line with 4 spaces and when that didn't work I added it with one tab.</p>
  
  <p>It's at the exact same indentation level as the previous line. So I don't know why this error is happening. </p>
