Computer science with python project BMI Calculator (GUI)

In this tutorial I am going to create a simple GUI based Python project called BMI Calucator ideal for CBSE Class XI-XII subject Computer science with Python. With out wasting time Let’s see how to create a simple BMI Calculator with Python, In this project I am using tkinter for GUI.

Project Requirement

1. Python 3.X
2. Tkinter Library

    wt = float((wt.get()))
    ht=ht/100
    bmi=float(wt / (ht*ht))
    bmi=round(bmi,1)
