title: how to convert format time "hhmmss.ss" to "hh:mm:ss.ss" in python
body: <p>I have time in series, let's say 002959.20. I would like to change in this format 00:25:59.20 with timezone (+7.00) or 07:25:59. I have tried with 'strftime', but it's not working. How can i change the format? really appreciate any help! :)</p>
  
  <p><strong>edit</strong>
  Here's my data:</p>
  
  <pre><code>$PU    003114.00
  $PU    003114.20
  $PU    003114.40
  $PU    003114.60
  $PU    003114.80
  Name: Time, dtype: object
  </code></pre>
  
  <p>Here's my code:</p>
  
  <pre><code>y =  (New[Time])
  import time
  time.strftime(y,'%H:%M:%S.%f')
  
  output:
  TypeError: strftime() argument 1 must be str, not Series
  </code></pre>
  
  <p>and I tried to convert to string </p>
  
  <pre><code>TypeError: Tuple or struct_time argument required
  </code></pre>
