How to create a GUI Calculator in Python – Python Tkinter GUI | Python Project
Python is a popular programming language known for its simplicity and versatility. Tkinter is the standard GUI toolkit for Python that allows developers to create user-friendly interfaces. In this article, we will discuss how to create a GUI Calculator using Python Tkinter.
Step 1: Install Tkinter
If you haven’t installed Tkinter, you can do so by running the following command:
pip install tkinter
Step 2: Import Tkinter
Once Tkinter is installed, you can import it into your Python script using the following code:
from tkinter import *
Step 3: Create the Calculator GUI
Now, you can start creating the GUI of the calculator using Tkinter. Below is an example of how to create a simple calculator interface:
# Create the main window
root = Tk()
root.title("Simple Calculator")
# Create the display widget
display = Entry(root, width=20, borderwidth=5)
display.grid(row=0, column=0, columnspan=4)
# Create the number buttons
button_1 = Button(root, text="1", padx=20, pady=20)
button_2 = Button(root, text="2", padx=20, pady=20)
# Add more number buttons as needed...
# Create the operator buttons
add_button = Button(root, text="+", padx=20, pady=20)
subtract_button = Button(root, text="-", padx=20, pady=20)
# Add more operator buttons as needed...
# Add the buttons to the grid
button_1.grid(row=1, column=0)
button_2.grid(row=1, column=1)
# Add more button grids as needed...
add_button.grid(row=2, column=0)
subtract_button.grid(row=2, column=1)
# Add more operator button grids as needed...
# Run the main loop
root.mainloop()
Step 4: Create the Calculator Functions
Finally, you can add the functionality to the calculator buttons. This involves creating functions that perform the arithmetic operations and updating the display accordingly. Below is an example of how to create the addition function:
def add():
# Get the numbers from the display
num1 = int(display.get())
num2 = int(display.get())
# Perform the addition
result = num1 + num2
# Update the display with the result
display.delete(0, END)
display.insert(0, result)
Step 5: Run the Calculator
Once you have created the calculator GUI and functions, you can run the Python script to see the GUI calculator in action.
Creating a GUI Calculator in Python using Tkinter is a great project for beginners to get hands-on experience with building user interfaces and implementing functionality. With the simplicity of Python and the versatility of Tkinter, you can create a powerful and user-friendly calculator that can be used by anyone.
