Main Code
Now that we know what we are going to develop. Let us start our Scientific Calculator in Python using the Tkinter development journey without wasting a single second. An in-depth explanation along with source code will be definitely a good experience to learn this project.
Basic library imports and window configuration
from tkinter import *
import math
import tkinter.messagebox
root = Tk()
root.title("Scientific Calculator")
root.configure(background = 'red')
root.resizable(width=False, height=False)
root.geometry("480x568+450+90")
calc = Frame(root)
calc.grid()Explanation:
Here we imported some libraries and set up the title for our Scientific Calculator in the Python window. We also used the geometry() function of the Tkinter library to set the size of the window. Besides that, we have also used a grid() function to place each and every box in its calculator at the correct position and designed the overall calc in the form of a grid.
Class definition for all the Scientific Calculator functions

self.display(self.current)Explanation:
In this code section, we used the class to add various functions. At first, we defined the class with the name Calc() and then defined all the functions that we want in want in our Scientific Calculator in Python in the form of a Python function. Apart from that, we have also defined the function to handle the input number entered by the user. Also, to check if the function is valid or not we have defined a separate function in this class. We have included almost all the important functions that are in a normal scientific calculator. In this, we have made use of a math library and various built-in functions in that library. These functions are called when the button relating to it is clicked by the user. The logic of the function is made using the functions provided by the math library.
To display the text
added_value = Calc()
txtDisplay = Entry(calc, font=('Helvetica',20,'bold'),
bg='black',fg='red',
bd=30,width=28,justify=RIGHT)
txtDisplay.grid(row=0,column=0, columnspan=4, pady=1)
txtDisplay.insert(0,"0")Explanation:
In this code block, we have defined a variable to store the Calc() class in it. On top of that, in order to display the text box, wherein the user can see the entered values and functions, we have added a text box and customized it according to our needs. To set the size of the textbox we made use of width. Here bd stands for border. We changed the fonts, background, and alignment of the text. We also used the grid() function of the Tkinter library to set its position in a proper way.
Adding and Arranging the numbers
numberpad = "789456123"
i=0
btn = []
for j in range(2,5):
for k in range(3):
btn.append(Button(calc, width=6, height=2,
bg='black',fg='red',
font=('Helvetica',20,'bold'),
bd=4,text=numberpad[i]))
btn[i].grid(row=j, column= k, pady = 1)
btn[i]["command"]=lambda x=numberpad[i]:added_value.numberEnter(x)
i+=1Explanation:
Here, in this part of Scientific Calculator in Python, we have defined a variable named “numberpad” that stores all the digits. Now in order to make a separate box for each of the digits, we made use of for loop. This loop helps us to create 9 boxes for 9 digits that will be of the same size and font. Using the for loop helps us to eradicate the need of writing the code 9 times to display the boxes.
Buttons to handle the Clear and Clear all operation
btnClear = Button(calc, text=chr(67),width=6,
height=2,bg='powder blue',
font=('Helvetica',20,'bold')
,bd=4, command=added_value.Clear_Entry
).grid(row=1, column= 0, pady = 1)
btnAllClear = Button(calc, text=chr(67)+chr(69),
width=6, height=2,
bg='powder blue',
font=('Helvetica',20,'bold'),
bd=4,
command=added_value.All_Clear_Entry
).grid(row=1, column= 1, pady = 1)Explanation:
In this part of the code for Scientific Calculator in Python, the two buttons help the user to handle the operation like clearing a digit or a function. The buttons for Clear All clear everything that is added in the textbox. In this also we have customized the buttons according to our needs.
Buttons for all operations of the Standard Calculator
btnsq = Button(calc, text="\u221A",width=6, height=2,
bg='powder blue', font=('Helvetica',
20,'bold'),
bd=4,command=added_value.squared
).grid(row=1, column= 2, pady = 1)
btnAdd = Button(calc, text="+",width=6, height=2,
bg='powder blue',
font=('Helvetica',20,'bold'),
bd=4,command=lambda:added_value.operation("add")
).grid(row=1, column= 3, pady = 1)
btnSub = Button(calc, text="-",width=6,
height=2,bg='powder blue',
font=('Helvetica',20,'bold'),

).grid(row=5, column= 0, pady = 1)
btnDot = Button(calc, text=".",width=6,
height=2,bg='powder blue',
font=('Helvetica',20,'bold'),
bd=4,command=lambda:added_value.numberEnter(".")
).grid(row=5, column= 1, pady = 1)
btnPM = Button(calc, text=chr(177),width=6,
height=2,bg='powder blue', font=('Helvetica',20,'bold'),
bd=4,command=added_value.mathPM
).grid(row=5, column= 2, pady = 1)
btnEquals = Button(calc, text="=",width=6,
height=2,bg='powder blue',
font=('Helvetica',20,'bold'),
bd=4,command=added_value.sum_of_total
).grid(row=5, column= 3, pady = 1)Explanation:
These above variables are for the buttons that are for performing various operations like Multiply, Divide, Subtract, Add etc. These buttons when clicked, call the respective function that is attached to them, thus helping the user in performing the desired operation easily. For the design purpose, we made use of all the properties that are provided by the Button function of the Tkinter library. On top of that, a grid() function is also used somewhere.
Buttons for Scientific Calculator – Row 1
btnPi = Button(calc, text="pi",width=6,
height=2,bg='black',fg='red',
font=('Helvetica',20,'bold'),
bd=4,command=added_value.pi
).grid(row=1, column= 4, pady = 1)
btnCos = Button(calc, text="Cos",width=6,
height=2,bg='black',fg='red',

if iExit>0:
root.destroy()
return
def Scientific():
root.resizable(width=False, height=False)
root.geometry("944x568+0+0")
def Standard():
root.resizable(width=False, height=False)
root.geometry("480x568+0+0")
menubar = Menu(calc)Explanation:
In this section, we have the code to make up the Menubar. This will simply come on top of the calculator. We have added multiple options like File and Edit. Moreover, to handle the opening and closing of the Scientific calc window we have defined two new functions namely Standard() and Scientific(). Inside these functions, we have used the resizable and geometry functions of the Tkinter library.
Sub-options in Menu Bar
filemenu = Menu(menubar, tearoff = 0)
menubar.add_cascade(label = 'File', menu = filemenu)
filemenu.add_command(label = "Standard", command = Standard)
filemenu.add_command(label = "Scientific", command = Scientific)
filemenu.add_separator()
filemenu.add_command(label = "Exit", command = iExit)
editmenu = Menu(menubar, tearoff = 0)
menubar.add_cascade(label = 'Edit', menu = editmenu)
editmenu.add_command(label = "Cut")
editmenu.add_command(label = "Copy")
editmenu.add_separator()
editmenu.add_command(label = "Paste")
root.config(menu=menubar)
root.mainloop()
Explanation:
Talking about the sub-options in the “File” button there is a feature to switch between “Standard” and “Scientific” Calculator. Inside the “Edit” button there is Copy, Paste andCut option. These options will help to copy the answers, paste other values in this calc and also cut the answer. Whenever the user will click on the Scientific calculator, a window beside the Standard Calc will open up. A separate window helps a user to close and access Scientific calc with more use and thus we decided to code in such a way.
