  16  
  17      An IPython extension is an importable Python module that has
  18      a function with the signature::
  19  
  20          def load_ipython_extension(ipython):
  21              # Do things with ipython
  22  
  23      This function is called after your extension is imported and the
  24      currently active :class:`InteractiveShell` instance is passed as
  25      the only argument.  You can do anything you want with IPython at
  26      that point, including defining new magic and aliases, adding new
  27      components, etc.
  28  
  29      You can also optionally define an :func:`unload_ipython_extension(ipython)`
  30      function, which will be called if the user unloads or reloads the extension.
  31      The extension manager will only call :func:`load_ipython_extension` again
  32      if the extension is reloaded.
  33  
  34      You can put your extension modules anywhere you want, as long as
  35      they can be imported by Python's standard import mechanism.

  56          This function looks up the extension's name in ``sys.modules`` and
  57          simply calls ``mod.unload_ipython_extension(self)``.
  58  
  59          Returns the string "no unload function" if the extension doesn't define
  60          a function to unload itself, "not loaded" if the extension isn't loaded,
  61          otherwise None.

  72          If the module has not been loaded before,

  74          :func:`reload` is called and then the :func:`load_ipython_extension`
  75          function of the module, if it exists is called.
