Bug description:
The file tkinter/__init__.py contains the following code:
def trace_variable(self, mode, callback):
"""Define a trace callback for the variable.
MODE is one of "r", "w", "u" for read, write, undefine.
CALLBACK must be a function which is called when
the variable is read, written or undefined.
Return the name of the callback.
This deprecated method wraps a deprecated Tcl method that will
likely be removed in the future. Use trace_add() instead.
"""
# TODO: Add deprecation warning
trace = trace_variable
The deprecated Tcl method was removed from Tcl 9.0, before the deprecation warning was added in tkinter. The trace_variable() and trace() methods still exist in both the current tkinter/__init__.py and the replacement which was included in PR #124112. Calling those methods with Tk 9.0 raises a TclError.
