Where python is looking for a DLL open by ctypes.cdll. <Name> on the windows?

I am African. I could not find a simple answer to this on the Internet, so maybe in the future there will be one of them because of this question.

I am using pywiiuse, the python shell for the C wiiuse library on windows. I got some simple C examples by simply including the DLL, header and library in the source directory.

However, I am wondering where to put the dll so that pywiiuse will find it. A look at the source shows that it loads as follows:

dll = ctypes.cdll.wiiuse

Running the examples gives an exception not found by the module when I have a dll in the same directory as in my test case.
