The requirement is fairly broad; there are a number of things you could do to 
satisfy the requirement. Largely, it's up to you as long as the full license 
text is accessible somewhere. I will provide personal, entirely unofficial 
recommendations below, though.

The whole license and history text, parts A and B.

The whole thing.

Have a licenses\ directory with a LICENSE_Python.txt containing the whole 
license text. Have other LICENSE_<foo>.txt files for any other third-party 
libraries you use, like the GUI toolkit.

Link to the part of the online documentation that lists the third-party software 
that you use.
