In this article we will see how we can make a PyQt5 application which tells the real time price of the bitcoin. Modules required and Installation: PyQt5 : PyQt5 is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt5 is free software developed by the British firm Riverbank Computing.
pip install PyQt5
Requests : Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs.
pip install requests
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.
pip install beautifulsoup4
Steps to make application to get real time price of bitcoin – 1. Create a window and sets its dimension and title 2. Create a label to sHow the price 3. Create a push button 4. Add action to the push button 5. Inside the action with the help of requests fetch the data for price of bit coin 6. Using beautiful soup convert the data into html code and find the price and save it in variable 7. Change the text of the label, set price as text
Below is the implementation –
Python3
# importing librariesfrom bs4 import BeautifulSoup as BSimport requestsfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass Window(QMainWindow): def __init__(self): super().__init__() # setting title self.setWindowTitle("PyQt5 Bit Coin ") # setting geometry self.setGeometry(100, 100, 400, 600) # calling method self.UiComponents() # showing all the widgets self.show() # method for widgets def UiComponents(self): # creating label to show bit coin price self.label = QLabel("//BIT-COIN//", self) # setting geometry of label self.label.setGeometry(50, 150, 300, 50) # setting its alignment self.label.setAlignment(Qt.AlignCenter) # setting font to the label self.label.setFont(QFont('Times', 15)) # setting border to the push button self.label.setStyleSheet("border : 3px solid black;") # creating push button to show current price button = QPushButton("Show price", self) # setting geometry to push button button.setGeometry(150, 300, 100, 40) # adding method to the push button button.clicked.connect(self.show_price) # setting tool tip to button button.setToolTip("Press to get Bit Coin Price") def show_price(self): # url of the bit coin price url = "https://www.google.com/search?q = bitcoin + price" # getting the request from url data = requests.get(url) # converting the text soup = BS(data.text, 'html.parser') # finding meta info for the current price ans = soup.find("div", class_="BNeawe iBp4i AP7Wnd").text # setting this price to the label self.label.setText(ans)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
