In this article we will see how we can create a PyQt5 application which tells about the cases of corona around the world i.e number of confirmed cases, number of cases in which patient has recovered and total deaths due to corona.
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. Create a push-button set its geometry
2. Create three labels to show information about total cases, recovered cases and death cases
3. Set geometry, alignment and border to each label
4. Add action to the push button
5. Inside the action scrap the data from the website with the help of requests BeautifulSoup
6. Convert the raw data into html code and then filter it to get the required output
7. Show the output the screen with the help of labels
Below is the implementation
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * from PyQt5.QtCore import * from bs4 import BeautifulSoup as BS import requests import sys class Window(QMainWindow): def __init__(self): super().__init__() # setting title self.setWindowTitle("Python ") # setting geometry self.setGeometry(100, 100, 400, 500) # calling method self.UiComponents() # showing all the widgets self.show() # method for widgets def UiComponents(self): # create push button to perform function push = QPushButton("Press", self) # setting geometry to the push button push.setGeometry(125, 100, 150, 40) # creating label to show the total cases self.label_total = QLabel("Total Cases ", self) # setting geometry self.label_total.setGeometry(100, 200, 200, 40) # setting alignment to the text self.label_total.setAlignment(Qt.AlignCenter) # adding border to the label self.label_total.setStyleSheet("border : 2px solid black;") # creating label to show the recovered cases self.label_reco = QLabel("Recovered Cases ", self) # setting geometry self.label_reco.setGeometry(100, 250, 200, 40) # setting alignment to the text self.label_reco.setAlignment(Qt.AlignCenter) # adding border self.label_reco.setStyleSheet("border : 2px solid black;") # creating label to show death cases self.label_death = QLabel("Total Deaths ", self) # setting geometry self.label_death.setGeometry(100, 300, 200, 40) # setting alignment to the text self.label_death.setAlignment(Qt.AlignCenter) # adding border to the label self.label_death.setStyleSheet("border : 2px solid black;") # adding action to the push button push.clicked.connect(self.get_cases) # method called by push def get_cases(self): # getting the request from url # converting the text soup = BS(data.text, 'html.parser') # finding meta info for total cases total = soup.find("div", class_="maincounter-number").text # filtering it total = total[1: len(total) - 2] # finding meta info for other numbers other = soup.find_all("span", class_="number-table") # getting recovered cases number recovered = other[2].text # getting death cases number deaths = other[3].text # filtering the data deaths = deaths[1:] self.label_total.setText("Total Cases : " + total) self.label_reco.setText("Recovered Cases : " + recovered) self.label_death.setText("Total Deaths : " + deaths) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() window.show() # start the app sys.exit(App.exec()) |
Output :
