Slip 6 A) Write python script using package to calculate area and volume of cube and sphere

Answer :

pi=22/7

radian = float(input('Radius of sphere: '))

sur_area = 4 * pi * radian **2

volume = (4/3) * (pi * radian ** 3)

print("Surface Area is: ", sur_area)

print("Volume is: ", volume)

# Python3 code to find area

# and total surface area of cube

def areaCube( a ):

    return (a * a * a)

 

def surfaceCube( a ):

    return (6 * a * a)

 

a = 5

print("Area =", areaCube(a))

print("Total surface area =", surfaceCube(a))

Output :

 

Slip 6 B) Write a Python GUI program to create a label and change the label font style (font name, bold, size). Specify separate check button for each style.

Answer :

from tkinter import *

import tkinter as tk

 

window = tk.Tk()

window.title('My Window')

window.geometry('500x500')

 

l = tk.Label(window, bg='white', width=20, text='Hello')

l.pack()

 

def print_selection():

 

    if(var1.get() == 0) & (var2.get() == 0) & (var3.get() == 0):

       l.config(text="Hello")

    elif (var1.get() == 1):

        l.config(text="Hello", font=("Arial"))

    elif (var2.get() == 1):

        l.config(text="Hello", font=("Arial Bold",20))

    elif (var3.get() == 1):

        l.config(text="Hello", font=("Arial", 70))

    else:

        l.config(text="Hello", font=("Arial Bold", 70))

 

var1 = tk.IntVar()

var2 = tk.IntVar()

var3 = tk.IntVar()

c1 = tk.Checkbutton(window, text='Font Style',variable=var1, onvalue=1, offvalue=0, command=print_selection)

c1.pack()

c2 = tk.Checkbutton(window, text='Bold',variable=var2, onvalue=1, offvalue=0, command=print_selection)

c2.pack()

c3 = tk.Checkbutton(window, text='Size = 70',variable=var3, onvalue=1, offvalue=0, command=print_selection)

c3.pack()

window.mainloop()

 

Output :
