How to export values in one shape to multi shape.....

I will try to explain... I have one shape (Districts) with 40 values (40 districts)...
I need to create 40 shapes now... one shape per District.
I can do this manual... one by one... using the tool export data (selected by atributte)...

How can I make this 40 shapes automaticly???
Do we have a tool for this purpose? Just with Python? Suggestions?

Thank you very much.
