Read the PSF license perhaps 3 times.
Then do what I said in my first response.

If you distribute the program, you should include a license file.  At 
the bottom, put something like

"This program includes the following idlelib modules from Python x.y.z, 
https://python.org/... copyright <<copyright notice from clause 2>>. 
<<If you modify them, briefly describe>>.

Notice that the Python license file has similar notices at the bottom 
for copyrighted modules that Python distributes.  (None of the idlelib 
modules are.)  Take a look to see what form they follow.
