[wxPython-users] wx.ComboBox SetSelection on ClientData

[Raffaello Barella]

Surely your idea of using a dictionary is more elegant, and since you have
made up a numeric dict the additional memory cost is trivial. Beyond the
inquiry is made in C++, not Python, so much faster: and  the combo content
might become very long. Thank you for your suggestion.
