印度的冠状病毒详细信息 – 使用Python PyQt5

在本文中，我们将了解如何创建一个 PyQt5 应用程序，该应用程序可以提供冠状病毒病例的详细信息，即印度的总病例、康复病例和总死亡人数，即各州的结果。

Modules required and Installation:

PyQt5 : PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the British firm Riverbank Computing.

Requests : Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs.

Beautiful Soup: Beautiful Soup is a library that makes it easy to scrape information from web pages. It sits atop an HTML or XML parser, providing Pythonic idioms for iterating, searching, and modifying the parse tree.

Implementations steps :

1. Get coronavirus state wise list and store it in a list
2. Create a non-editable combo box, set its geometry
3. From list get the state names and add it to the combo box
4. Create three labels to show information about total cases, recovered cases and death cases
5. Set geometry, alignment and border to each label
6. Add action to the combo box
7. Inside the action filter the list to get desired information
8. Show the output the screen with the help of labels
