title: Run a python file with arguments in Colab
body: <p>I am trying to run a python (<code>test.py</code>) file in Colab. The file needs inputting some parameters, e.g., &quot;--epoch&quot;, &quot;--class_file&quot;. What I did is:</p>
  <pre><code>!python test.py &quot;--epoch&quot; 100 &quot;--class_file&quot; class_file
  #class_file is a path string 
  </code></pre>
  <p>After argument parsing, the <code>class_file</code> is not interpreted as the intended path string, but instead a string like <code>class file = &quot;class_file&quot;</code>. How did that happen?</p>
