Fortunately your code reveals that you're using "tk" here, but otherwise, please state up-front which GUI library you're using; there are quite a few. > This line of code works for the highlighted text: > > text2copy = self.text.get(tk.SEL_FIRST, tk.SEL_LAST) > > However, this code will generate an exception if no text > is highlighted.

You're trying to do one of two things: 1) Copy the selected text to the clipboard 2) If there isn't any, copy all the text. So I would say yes, the basic layout of try/except to get the text is perfect. However, DON'T use a bare "except:" clause. You'll get back a specific exception; catch that instead. Other than that, sure, your code looks fine. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
