This article focuses on the evaluation of mathematical expression using the Tkinter and math packages in Python.
Tkinter: Python Tkinter is a GUI programming package or built-in package. Tkinter provides the Tk GUI toolkit with a potent object-oriented interface. Python with Tkinter is the fastest and easiest way to create GUI applications. Creating a GUI using Tkinter is an easy task.
Math module: In python, a variety of mathematical operations can be carried out with ease by importing a python module called “math” that specifies various functions, making our tasks simpler.
Steps involved in conversion of temperature:
- Importing the tkinter & math packages.
- Create the main window.
- Add number of widgets to the main window : Entry , Label.
- Evaluating the expression.
- Displaying message.
- Apply the event trigger on the widgets.
