[New-bugs-announce] [issue21402] tkinter.ttk._val_or_dict assumes tkinter._default_root exists

[Stephen Paul Chappell]

New submission from Stephen Paul Chappell:

If a call is made to tkinter.NoDefaultRoot, then calls to tkinter.ttk._val_or_dict may fail. NoDefaultRoot ends with "del _default_root" (line 174) and removes the variable from the module's namespace. _val_or_dict can try to access this variable but assumes that it exists (line 319). If _default_root does not exist, the function will raise an AttributeError: 'module' object has no attribute '_default_root'.
