title: Python: AttributeError: 'int' object has no attribute 'replace'
body: <p>I'm new to python and my in my first program I'm trying to extract metadata from FLAC files to rename them.</p>
  
  <p>This particular part of my code is causing me some trouble:</p>
  
  <pre><code>import subprocess
  
  filename = raw_input("Path?")
  
  title = subprocess.call(
       ["metaflac", "--show-tag=title", filename])
  new_title = title.replace("TITLE=", "")
  
  print new_title
  </code></pre>
  
  <p>'metaflac --show-tag=title file.flac' sends back "TITLE=foo" and I'm trying to get rid of "TITLE=".</p>
  
  <p>The problem is, when I run this, I get this back:</p>
  
  <pre><code>TITLE=foo
  Traceback (most recent call last):
     File "test.py", line 16, in &lt;module&gt;
       title = title.replace("TITLE=", "")
   AttributeError: 'int' object has no attribute 'replace'
  </code></pre>
  
  <p>I just don't understand how can the string "TITLE=Début d'la Fin" can be an integer...</p>
