Python Functions

Problem Definition

Create a python window containing a grid of 2×2 buttons. In that window, place 4 buttons that have 4 different functionalities:

Button 1: Pressing Button 1 will print a random integer number.
Button 2: Pressing Button 2 will print a random float number.
Button 3: Pressing Button 3 will print a random lowercase word containing a-z
Button 4: Pressing Button 4 will print a random uppercase word containing A-Z

Tkinter Programming

Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. Creating a GUI application using Tkinter is an easy task.

Program


from tkinter import *
from tkinter import messagebox
import random
import string

def printRandomInt():
    r_int = random.randint(1,10000000)
    messagebox.showinfo("information","Random integer number: "+str(r_int))

def printRandomFloat():
    r_float = random.random()
    messagebox.showinfo("information","Random float number: "+str(r_float))

def printRandomSmall():
    r_small = random.choice(string.ascii_lowercase)
    messagebox.showinfo("information","Random lowercase character: "+r_small)

def printRandomCap():
    r_float = random.choice(string.ascii_uppercase)
    messagebox.showinfo("information","Random uppercase character: "+r_float)


class Window(Frame):

    def __init__(self, master=None):
        Frame.__init__(self, master)                 
        self.master = master
        self.init_window()

    def init_window(self):
        #self.pack(fill=BOTH, expand=1)
        self.pack()
        button1 = Button(self, text = "Print Random Integer", fg = "Black", bg = "White", command = printRandomInt)
        button2 = Button(self, text = "Print Random Float", fg = "Black", bg = "White", command = printRandomFloat)
        button3 = Button(self, text = "Print Random Small", fg = "Black", bg = "White", command = printRandomSmall)
        button4 = Button(self, text = "Print Random Cap", fg = "Black", bg = "White", command = printRandomCap)
        button1.grid(row = 1, column = 1,padx=10,pady=50)
        button2.grid(row = 1, column = 2,padx=10,pady=50)
        button3.grid(row = 2, column = 1,padx=10,pady=10)
        button4.grid(row = 2, column = 2,padx=10,pady=10)

root = Tk()
#root.configure(background = "light blue")
root.title("Random Generator")
root.geometry("450x250")

app = Window(root)
root.mainloop()
