How to Create Very Beautiful Weather Showing app Using Python For Windows, Linux and Mac OS | python web scraping | python gui | python example

hii readers,

                     This Tutorial Is About How We Can Create Weather App Using Python And Tkinter. First of all, I want to clear that this is only for educational and practice purpose only. That's Why I will Not take any type of responsibility for this app.

So, let's Start,

But First, Here, I am Sharing Some Screen Shots of My App:





looking cool! hahaha, I know.

Requirements:

           1. Tkinter (Built-In) 
           2. BeautifulSoup (Use "pip install BeautifulSoup" For Automatically Installation)


Features:

          1. Cross-Platform Support 
          2. Good Internet Connection Handling System  
          3. Automatic Features Auto-Show and Auto-Hide GUI Widget

 So, Let's Start, 

      For This Project, I am Using MVC Technique (Model, View, Control).

So, For This Example. first I Created 3 Files

        1. weather
        2. view
        3. main

Let Me Explain You What Are The Functions of these files,

Here,
               Weather Script Is For Connecting To Internet and Scraping All Data And Providing Useful Data in Dictionary.

  The view is For GUI and Main is For Controlling Both Script and Other Controlling Systems.

Looking Hard! hmmm,

don't worry, this project is really very easy. :)

1. weather => for Downloading weather-related data.
