I'm using Chapter 9 in Mark Roseman's "Modern Tkinter for Busy Python
Developers" to learn how to write a top level menu. MWE code is attached.
Python3 tells me there's invalid syntax on line 42:
self.['menu'] = menubar # attach it to the top level window
^
yet that's the syntax he prints on page 84 (and has in the book's code
supplement).
It is a simple typo, remove the dot.
self['menu'] = menubar
It will then stop at the add_cascade, fix it like this:
menubar.add_cascade(menu=self.menu_file, label='File')
and then it works,
Why am I getting an invalid syntax error here?
Because the dot would indicate the access of an attribute. but no name
follows. What it does here, instead, is indexing - the correct line is
similar to setting a dict entry.
