Anyone who wants to create a calculator with python can use this code
from tkinter import*

def btnClick(numbers):
global operator
operator=operator + str(numbers)
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=""

cal = Tk()
cal.title(“Calculator”)
operator=""
text_Input =StringVar()

txtDisplay = Entry(cal,font=(‘arial’ , 20,‘bold’), textvariable=text_Input, bd=30, insertwidth=4,
bg=“powder blue”, justify=‘right’).grid(columnspan=4)

btn7=Button(cal,padx=16,pady=16,bd=8, fg=“black” ,font=(‘arial’, 20,‘bold’),
text=“7”,bg=“powder blue”,command=lambda:btnClick(7)).grid(row=1,column=0)

Hey @codeemaker :wave:

Moving this to #off-topic since Python code will not run in a Thunkable app.

If you’re interested in using Thunkable to create a calculator app then there are lots of examples.

Here’s one that was created recently:

Hope that helps!
