need help with combobox Python 2.7

[Larz60+]

Look at the links I put in the post. They point to docs I believe you need.
It's not difficult. Here's one I did in wxpython:

    def rfc_selector_load(self):
        """
        Clears, then Loads self.rfc_selector ListCtrl with data from self.rfc_index dictionary.
        :return: None
        """
        self.rfc_selector.DeleteAllItems()
        for key, value in self.rfc_index.items():
            index = self.rfc_selector.GetItemCount()
            self.rfc_selector.InsertItem(index, key)
            self.rfc_selector.SetItem(index, 1, value['title'])
