If pathname is a plain directory, listdir *.py and enter all modules. Else, pathname must be a Python *.py file and the module will be put into the archive. Added modules are always module.pyc. This method will compile the module.py into module.pyc if necessary. If filterfunc(pathname) is given, it is called with every argument. When it is False, the file or directory is skipped. r� r� z%s %r skipped by filterfuncNz __init__.pyz%s/%szAdding package in�asr r ZAdding)� filterfuncz.pyz file %r skipped by filterfunczAdding files from directoryz.Files added with writepy() must end with ".py"z Adding file���r� r� r� r� )ru r� rK r� r� r` r� r0 �isfile� _get_codenamer� �listdir�remove�splitext�writepyr� )r| �pathname�basenamer� Zlabel�dirr Zinitnamer� r� Zdirlistr? r� �rootZextr r r r� � sx zPyZipFile.writepyc s d� fdd� }|d }|d }t jj|dd�}t jj|dd�}t jj|dd�}� jdk�r\tjj|�r�tj|�jtj|�jkr�| } } n�tjj|�r�tj|�jtj|�jkr�|} |} n�tjj|�r�tj|�jtj|�jkr�|} |} nvtjj|��rtj|�jtj|�jk�r|} |} nD||��rRt j j d k�r4|} nt j j dk�rH|} n|} |} n| } } n�� jd k�rr|} |} n<|} � jdk�r�|} n&� jdk�r�|} nd j � j�} t | ��tjj| ��o�tj| �jtj|�jk�s�||� jd ��s�| } } tjj| �d } |�rd || f } | | fS )a Return (filename, archivename) for the path.
