[Python-Dev] Proposed Python api for testing whether a module exists (original) (raw)

I propose to add the following function to the imp module:

exists(module_name)

  Test whether the named module can be found.

  This method should be used when you want to perform
  alternate actions depending on whether a module is available.

  Returns True of the module can be found and False otherwise.
  A True return value does not guarentee that the module will be
  importable.  The module will not be imported as a result of
  calling exists, but parent modules may be.

  If a dotted module name is given, then parent modules will be
  imported if they haven't already been imported.

If there are no objections, I'll try to get this in before Wednesday night.
