Python 3 Tkinter GUI Script to Scrape Air Quality Index Information Using BeautifulSoup4 Library Full Project For Beginners



In order to get started you need to install the below libraries using the pip command as shown below



pip install requests



pip install bs4



After installing this library you need to make an file and copy paste the following code



# import modules
from tkinter import *
import requests
from bs4 import BeautifulSoup

# link for extract html data

def getdata(url):
    r = requests.get(url)
    return r.text

def airinfo():
    htmldata = getdata(
    soup = BeautifulSoup(htmldata, 'html.parser')
    # Traverse the air quality
    for item in (soup.find_all("div",
        res_data = item.get_text()

        # traverse the content
    data = ''
    for item in (soup.find_all("div",
        data += item.get_text()
        data += " "
    air_data = data.split(" ")
    res = int(res_data)
    if res <= 50:
        remark = "Good"
        impact = "Minimal impact"
    elif res <= 100 and res > 51:
        remark = "Satisfactory"
        impact = "Minor breathing discomfort to sensitive people"
    elif res <= 200 and res >= 101:
        remark = "Moderate"
        impact = "Breathing discomfort to the people with lungs, asthma and heart diseases"
    elif res <= 400 and res >= 201:
        remark = "Very Poor"
        impact = "Breathing discomfort to most people on prolonged exposure"
    elif res <= 500 and res >= 401:
        remark = "Severe"
        impact = "Affects healthy people and seriously impacts those with existing diseases"
