Scientific Calculator With Python

Hey coder!!! In this article we will explain step by step how to create Scientific Calculator in Python , using the tinker library of Python.

We all need a scientific calculator sometimes, because now i am doing CSE engineering, so I need this now. Well, we all need it sometimes and we go to buy it. Why don’t we make it ourselves today and that too for free. Without any plastic or environmentally harmful elements, we will make it from our laptop by coding in Python.

In this project, using tkinter and math library of Python.

Lets start the project Scientific Calculator In Python

First of all we will install Python and download the interpreter, after that we will import some libraries by using the import function.

using this line for import modules in command prompet “pip install <module-name>” .

Output Preview:-

Calculator using Python

First of all you have installed all of the necessary packages and tools, you are ready to start creating your projects.

Step 1: Import Libraries:-

import tkinter
import math

Here, These are some modules which we have to import

Step 2: Define the Calculator Functions:-

def click(val):
    # Function to handle button clicks and perform corresponding actions

This function works by clicking the button of the calculator.

Step 3: Create the GUI Window:-

root = tkinter.Tk()
root.title("Scientific Calculator")
root.geometry("680x486+100+100")
root.config(bg="black")

Step 4: Create Entry Field:-

entry = tkinter.Entry(root, font=("arial", 20, "bold"), bg="black", fg="white", bd=10, width=30)
entry.grid(row=0, column=0, columnspan=8)

A entry field is added to GUI to display the input and output.

Step 5: Create Buttons:-

button_list = ["C", "CE", "√", "+", "π", "cosθ", "tanθ", "sinθ", "1", "2", "3", "-", "2π", "cosh", "tanh", "sinh",
               "4", "5", "6", "*", chr(8731), "x\u02b8", "x\u00B3", "x\u00B2", "7", "8", "9", chr(247), "ln", "deg",
               "rad", "e", "0", ".", "%", "=", "log10", "(", ")", "x!"]

in this line of code , list the button is added with their respective labels.

Step 6: Place Buttons on the GUI:-

r = 1
c = 0
for i in button_list:
    button = tkinter.Button(root, width=5, height=2, bd=2, text=i, bg="black", fg="white",
                            font=("arial", 18, "bold"), command=lambda button=i: click(button))
    button.grid(row=r, column=c, pady=1)
    c += 1
    if c > 7:
        r += 1
        c = 0

In this line of code , Position button on the GUI 

Step 7: Run the Scientific Calculator in Python:-

root.mainloop()

This is the code after all , Tkinter loop function has been used to run the GUI.

Full code:-

# Importing the library
import tkinter
import math
# To provide functionalities
def click(val):
    e = entry.get()  # getting the value
    ans = " "
    try:
        # To clear the last inserted text
        if val == "C":
            e = e[0:len(e) - 1]  # deleting the last entered value
            entry.delete(0, "end")
            entry.insert(0, e)
            return
        # To delete everything
        elif val == "CE":
            entry.delete(0, "end")

            ans = math.e
        # log10 value
        elif val == "log10":

            return
        elif val == "=":
            ans = eval(e)
        else:
            entry.insert("end", val)
            return
        entry.delete(0, "end")
        entry.insert(0, ans)
