    Byte-compile a collection of Python source files to either :file:`.pyc` or
-   :file:`.pyo` files in the same directory.  *py_files* is a list of files to
-   compile; any files that don't end in :file:`.py` are silently skipped.
-   *optimize* must be one of the following:

    * ``0`` - don't optimize (generate :file:`.pyc`)
    * ``1`` - normal optimization (like ``python -O``)
