Python is suggesting some naming conventions. Those state, that classes are using camel-case names. If they are applied, "winfo" is not a class - but instead either an object (= class/type instance) or a module. "winfo" is obviously related to graphical objects (windows, in particular). This means, you wont find it in "pure" Python. If it exists, it belongs to "Tkinter". I would look for "winfo" (or "WInfo" (potentially slightly differently camel-cased)) in the "Tk[inter]" documentation. Note, that "Tkinter" is a Python binding for the "tk" library. If you find something in the "tk" documentation, it is likely "translated" in a uniform way (to other "tk" objects) for "Tkinter". -- https://mail.python.org/mailman/listinfo/python-list
