title: Python - writing and reading from a temporary file
body: <p>I am trying to create a temporary file that I write in some lines from another file and then make some objects from the data.  I am not sure how to find and open the temp file so I can read it.   My code:</p>
  
  <pre><code>with tempfile.TemporaryFile() as tmp:
      lines = open(file1).readlines()
      tmp.writelines(lines[2:-1])
  
  dependencyList = []
  
  for line in tmp:
      groupId = textwrap.dedent(line.split(':')[0])
      artifactId = line.split(':')[1]
      version = line.split(':')[3]
      scope = str.strip(line.split(':')[4])
      dependencyObject = depenObj(groupId, artifactId, version, scope)
      dependencyList.append(dependencyObject)
  tmp.close()
  </code></pre>
  
  <p>Essentially I just want to make a middleman temporary document to protect against accidentally overwriting a file. </p>
