Your fresh eyes saw what I kept missing, menubar.add_cascade(menu=self.menu_file, label='File') I was going to add the 'self' there when I found what stopped the processing before it. Many thanks.

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.

tkinter: creating/attaching menubar to top level window
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).
Why am I getting an invalid syntax error here?
TIA,
Rich
