Formatting Tkinter windows (Python)

Question

Im making a simple Tkinter calculator, but I cannot properly line up input forms and buttons.

here is 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() 

I would like to align all this and make the plus and minus buttons under input formats, if someone could help, it would be great to thank you.

Answer 1

You can use the columnspan argument to place labels and records in two columns. Remember that the column index is also based on a null value:

 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) 

Another solution is to create a new frame and place buttons in it, forming a simple 2 by 2 grid.
