Live World Time Application using Python

Quiz

Live world time project is a GUI application which has been coded using basic Python and library called Tkinter. The option provides an ability to input a continent and country to show the current local time and open Google Maps with the country's location on the map.

Required Libraries

First, ensure that you have the following libraries installed −

Tkinter − It comes with Python for defining and designing Graphical user interface applications.
pytz − This library is used for time zones management.
webbrowser − This library is used to make a web-browser open URLs.

Installation

The installation can be done either using the PIP or through direct command prompt. Below are the code statements to install required libraries.

To install tkinter, use the following command −

pip install tkinter

To install pytz, use the following command −

pip install pytz

You can get the webbrowser module from the official documentation from the command prompt as follows −

python -m webbrowser -t "http://www.python.org"

Steps to Create Live World Time Application

Step 1: Import Necessary Libraries

Use the following code statements to import the required libraries −

Import datetime for handling date and time.
Import pytz for time zone conversions.
Import tkinter and ttk for GUI elements.
Import webbrowser to open URLs.

Step 2: Initialize Tkinter Window

To initialize tkinter window −

Create a window using Tk().
Set the window's title and size.

Step 3: Define the Functions

Below are the functions that are using to get the different task done in the project −

open_map() − This function opens Google Maps based on the selected country.
update_map_and_time() − This function updates the displayed time and opens Google Maps.
update_countries(event) − This function updates the list of countries when a continent is selected.

Step 4: Create Dropdown Menus

You have to create dropdown menus for −

Continent selection.
Country selection, populated based on the continent.

Step 5: Display Current Time

To display the current time, use a label to show the local time of the selected country.

Step 6: Bind Functions to Events

Bind the following functions for −

Continent dropdown to update the country list.
Country dropdown to update the time and map.

Step 7: Run the Application

Use root.mainloop() to start the Tkinter event loop.

Code to Create Live World Time Application

def open_map():
   map_url = f"https://www.google.com/maps/search/?api=1&query={country_var.get().replace(' ', '+')}"
   webbrowser.open(map_url)
