Scientific GUI Calculator using Tkinter in Python

Prerequisite: Python GUI – tkinter

In this article, we are going to create GUI Scientific Calculator using Python. As you can see, calculating large numbers nowadays is difficult or time-consuming. We've created a simple Scientific Calculator GUI using Python that allows you to perform simple and complex calculations. To implement GUI we will use the Tkinter module of Python.

Stepwise Implementation

Step 1: Import module

Step 2:  Here we will create geometry or a so-called layout for the GUI of the calculator by using Tkinter.

Step 3: Now we will create a class in which we will create all the functions of the scientific calculator so that they can be called and perform easily.

Step 4: The below code will create a display in the GUI of the calculator by passing the font style, font size, background color, foreground color as an argument inside the entry function. 

Step 5: Here we will create a number pad for the calculator. 

Step 6:  Now we will place all the buttons/operators in their respective position in the grid. This is up to you to set them as per your choice by changing their row and column value. In this, each button function is just taking the name of the operator, width, height, background, foreground, font, and respective column & row position of the button as an argument. 

Step 7: Now at last we will create a menubar of the calculator GUI. 

Below is the complete implementation:
