Multiply function using Tkinter

[frankjoesmith]

Hello Everyone, i am stuck at the multiply function using Tkinter, any help is greatly appreciated. Addition seems to be fine.

for the multiplication, I have corrected the mistake you made.
see below the full working code.

from tkinter import *
root=Tk()

 
 
def calc_sum(event):
    num1 = float(num1Entry.get())
    num2 = float(num2Entry.get())
 
    sum = num1 + num2
 
    sumTotalEntry.grid(row=0,column=4)
    sumTotalEntry.insert(0,sum)
 
def multiply_num(event):
    num3=  float(mul1Entry.get())
    num4=  float(mul2Entry.get())
 
    mul= (num3) * (num4)
 
    #mulTotalEntry.delete(0,mul)
    mulTotalEntry.grid(row=1,column=4)
    mulTotalEntry.insert(0,mul)

numm1 = DoubleVar()
numm2 = DoubleVar()

numm3 = DoubleVar()
numm4 = DoubleVar()

num1Entry = Entry(root,textvariable=numm1)
num1Entry.grid(row=0)
 
plusLabel = Label(root,text="+",font=("Verdana",8))
plusLabel.grid(row=0,column=1)
 
num2Entry = Entry(root,textvariable=numm2)
num2Entry.grid(row=0,column=2)
 
equalButton=Button(root,text="=",font=("Verdana",8))
equalButton.bind('<Button-1>',calc_sum)
equalButton.grid(row=0,column=3)
 
sumTotalEntry=Entry(root)
sumTotalEntry.grid(row=0,column=4)
 
 
 
mul1Entry = Entry(root,textvariable=numm3)
mul1Entry.grid(row=1)
 
mulLabel = Label(root,text="*",font=("Verdana",8))
mulLabel.grid(row=1,column=1)
 
mul2Entry = Entry(root,textvariable=numm4)
mul2Entry.grid(row=1,column=2)
 
equalButton2=Button(root,text="=",font=("Verdana",8))
equalButton2.bind('<Button-1>',multiply_num)
equalButton2.grid(row=1,column=3)
 
mulTotalEntry=Entry(root)
mulTotalEntry.grid(row=1,column=4)
 
root.mainloop()
