Beginner’s Guide to Creating a BMI Project using PySimpleGUI

In this PySimpleGUI tutorial, we will be creating a BMI calculator project for beginners. PySimpleGUI is a simple and easy-to-use Python library for creating graphical user interfaces (GUI) and is perfect for those who are new to programming or GUI development.

To start this project, you will need to have Python installed on your computer. You can download Python from the official website (https://www.python.org/downloads/).

First, you will need to install PySimpleGUI using pip. Open a command prompt and run the following command:

pip install PySimpleGUI

Once PySimpleGUI is installed, you can start working on the BMI calculator project.

1. Import the necessary modules:

import PySimpleGUI as sg

1. Create the layout of the GUI:

layout = [
    [sg.Text('Enter your weight (in kg):'), sg.InputText(key='-WEIGHT-')],
    [sg.Text('Enter your height (in cm):'), sg.InputText(key='-HEIGHT-')],
    [sg.Button('Calculate BMI'), sg.Button('Exit')],
    [sg.Text(size=(30,1), key='-RESULT-')]
]

1. Create the PySimpleGUI window:

window = sg.Window('BMI Calculator', layout)

1. Create the BMI calculation function:

def calculate_bmi(weight, height):
    bmi = weight / ((height/100)**2)
    return bmi

1. Create the event loop:

while True:
    event, values = window.read()

    if event == sg.WIN_CLOSED or event == 'Exit':
        break
    elif event == 'Calculate BMI':
        weight = float(values['-WEIGHT-'])
        height = float(values['-HEIGHT-'])

        bmi = calculate_bmi(weight, height)

        result = f'Your BMI is {bmi:.2f}'

        window['-RESULT-'].update(result)

1. Close the PySimpleGUI window:

window.close()

By following these steps, you can create a simple BMI calculator using PySimpleGUI. This project is a great way to practice using PySimpleGUI and basic Python programming concepts. Feel free to customize the layout and functionality of the GUI to suit your preferences.

I hope this tutorial was helpful for beginners looking to create their first GUI project using PySimpleGUI. Happy coding!
