I'd change this to c_s.value.

Same as above. Without using .value the whole example doesn't do a good job on explaining the subject.

@berkerpeksag I changed to print(c_s, c_s.value), since the content says that "c_wchar_p and c_void_p changes the memory location they point to...", I think observe the memory location changed in c_s is useful, too.

Are you sure about that one? Why does it print c_wchar_p...?

ah, is a mistake, it should be print(c_s, c_s.value)

If you really want to keep print(c_s), I'd say move c_s.value to a new line:
>>> print(c_s)
c_wchar_p(139966785747344)
>>> print(c_s.value)

Fix this problem, and add a comment to point out that memory location has changed.
