Hi guys. I've been practicing my Tkinter skills by trying to make a simple calculator, but I'm having issues properly lining up the input forms and the buttons

Here's my current code

```from Tkinter import *

def calculate():
try:
num1 = float(enter1.get())
num2 = float(enter2.get())
result = num1 * num2
label3.config(text=str(result))
except ValueError:
label3.config(text='Enter numeric values!')
def calculate2():
try:
num1 = float(enter1.get())
num2 = float(enter2.get())
result = num1 / num2
label3.config(text=str(result))
except ValueError:
label3.config(text='Enter numeric values!')
def calculate3():
try:
num1 = float(enter1.get())
num2 = float(enter2.get())
result = num1 + num2
label3.config(text=str(result))
except ValueError:
label3.config(text='Enter numeric values!')
def calculate4():
try:
num1 = float(enter1.get())
num2 = float(enter2.get())
result = num1 - num2
label3.config(text=str(result))
except ValueError:
label3.config(text='Enter numeric values!')

root = Tk()

label1 = Label(root, text='First Number:')
label1.grid(row=0, column=1)
enter1 = Entry(root, bg='white')
enter1.grid(row=1, column=1)

label2 = Label(root, text='Second Number:')
label2.grid(row=2, column=1)
enter2 = Entry(root, bg='white')
enter2.grid(row=3, column=1)

btn1 = Button(root, text='X', command=calculate)
btn1.grid(row=4, column=1)
btn2 = Button(root, text='/', command=calculate2)
btn2.grid(row=5, column=1)
btn3 = Button(root, text='+', command=calculate3)
btn3.grid(row=5, column=2)
btn4 = Button(root, text='-', command=calculate4)
btn4.grid(row=4, column=2)

label3 = Label(root)
label3.grid(row=6, column=1)

enter1.focus()

enter1.bind('<Return>', func=lambda e:enter2.focus_set())

root.mainloop()```

```This is what my output looks like
```
```I would like to line up all the operator buttons under the input field. How can i do that.
```

Tkininter comes with the columnspan argument to span the labels and the entries two columns. As a side note, remember that the column index is also zero-based:

```label1.grid(row=0, column=0, columnspan=2)
enter1.grid(row=1, column=0, columnspan=2)
label2.grid(row=2, column=0, columnspan=2)
enter2.grid(row=3, column=0, columnspan=2)

btn1.grid(row=4, column=0)
btn2.grid(row=5, column=0)
btn3.grid(row=5, column=1)
btn4.grid(row=4, column=1)

label3.grid(row=6, column=0, columnspan=2)```
