I'm sorry if you don't like the design of the pack() method, but all the examples in the documentation show how it behaves. It is behaving as documented and designed.

https://docs.python.org/3/library/tkinter.html


The bug here is in your own code. You already know the correct way to write this, as you already stated:

    label2 = ttk.Label(root, text='Show2 Label')
    label2.pack()

Writing it as ttk.Label(root, text='Show2 Label').pack() returns None, as designed, which then consequently fails when you try to operate on None.

You say:

"If giving a widget a name, I expect to use it later in the program."

But you don't give the widget a name. What you are doing is the equivalent of this:

    temp = ttk.Label(root, text='Show2 Label')  # hidden temp object
    label = temp.pack()  # Returns None
    del temp  # hidden temp object is garbage collected

except that `temp` is never directly accessible by you.

Or if you prefer another analogy:

    number = (1 + 2) - 3

and then get surprised that number is zero rather than 3 because "I gave (1+2) a name". No, you gave a name to the *whole expression*, which evaluates to 0, not 3. And in the Label case, the *whole expression* evaluates to None.

Also, the code doesn't crash. It raises an exception, which is the expected behaviour for trying to access non-existent attributes.
