NameError: name 'No' is not defined

Question

When i press any number in my calculator showing error

from tkinter import *

def btnclick (numbers):
    global operator
    operator=operator + str(No)
    text_Input.set(operator)

def btnClearDisplay():
    global operator
    operator=""
    text_Input.set("")

def btnEqualsInput():
     global operator
     sumup=str(eval(operator))
     text_Input.set(sumup)
     operator=""

Error:

line 5, in btnclick
    operator=operator + str(No)
NameError: name 'No' is not defined

Uh... yeah. `No` isn't defined. What did you expect `No` to refer to when you wrote `operator=operator + str(No)`? — user2357112, May 24 '20 at 04:59

Try this: operator = operator + str(numbers) because your function parameter is numbers.
