Python tkinter widgets: Exercise-9 with Solution

Write a Python GUI program to create three radio buttons widgets using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
parent = tk.Tk()
parent.title("Radiobutton ")
parent.geometry('350x200')
radio1 = tk.Radiobutton(parent, text='First', value=1)
radio2 = tk.Radiobutton(parent, text='Second', value=2)
radio3 = tk.Radiobutton(parent, text='Third', value=3)
radio1.grid(column=0, row=0)
radio2.grid(column=1, row=0)

Sample Output:

Python: Tips of the Day

Time it:

timeit library is great for timing Python execution times. Just pass a function in string format to timeit.timeit() method and it will carry out 1 million executions to report the minimum time the code takes.

Its very useful to compare small code pieces and different functions but can be sluggish with big code.

Check out the example below demonstrating the execution time difference between 2 very similar list comprehension methods in Python:

import timeit
lst1='''list(range(100))'''
lst2='''[i for i in range(100)]'''
a=timeit.timeit(lst1)
b=timeit.timeit(lst2)
print(a, b, sep="------")
