How can I identify if there is text?
Multi tool use
I want to identify if there is text on canvas in tkinter.
Can anybody help me please? I have to find out if there is text to avoid an UnboundLocal Error.
Thanks!
If you want to access and update the text variable from the global scope, do so with global. If text is not defined in that scope, you can catch the NameError exception raised.
If text is global, you can use if text not in globals() to check if text is defined. Furthermore, you can use if globals().get('text') which will return False if text is either empty or not defined:
You can do the same thing with locals() inside a function
