How do I make pyCharm stop hiding (unfold) my Python imports?

Every time I open a Python file PyCharm will hide all imports and shows:

    import ...

within the editor.

I have to manually unfold it to see the imports. Where do I find the setting to undo auto-hiding of import statements?

As this question may be useful for people who also are not looking for the term "code folding", I'll make my comment an answer.

As extracted from IntelliJ IDEA 13.1.0 Web Help, but also worked on PyCharm CE 3.4.1:

  1. Open the IDE Settings (File > Settings, or Ctrl+Alt+S).
  2. Under the "Editor" node, click "Code Folding". The "Code Folding" page is displayed.
  3. In the "Collapse by default list", select the check boxes to the left of the code constructs you want to be displayed collapsed. So here you can uncheck "Imports".
  4. Apply changes.
