Previous code:

def clrbut():  
   textin.set('')

Explanation: After I click CE button then the numbers are just got hidden from the user side... Later when I click any number then the old number shows up again. which will be a problem for calculation and needs to rerun the application.

Code Fix:

def clrbut():  
   global operator
   operator = ""
   textin.set("")

Explanation: What this does is when I click CE button, It not only removed the numbers from the user side but also removes it from the backend side...
