4. Copy the code below into your file.

Write the Code

import numpy as np
import matplotlib.pyplot as plt
 
class RealTimeAirQualityMonitoring:
    def __init__(self):
        pass
 
    def get_air_quality_data(self):
        # Simulate real-time air quality data
        data = np.random.normal(loc=50, scale=10, size=100)
        print(f"Air quality data: {data}")
        return data
 
    def plot_data(self, data):
        plt.plot(data)
        plt.title('Real-Time Air Quality Monitoring')
        plt.xlabel('Time')
        plt.ylabel('AQI')
        plt.show()
 
    def demo(self):
        data = self.get_air_quality_data()
        self.plot_data(data)
 
if __name__ == "__main__":
    print("Real-Time Air Quality Monitoring Demo")
    monitor = RealTimeAirQualityMonitoring()
    monitor.demo()

    def get_air_quality_data(self):
        # Simulate real-time air quality data
        data = np.random.normal(loc=50, scale=10, size=100)
        print(f"Air quality data: {data}")
        return data
 
    def plot_data(self, data):

        plt.title('Real-Time Air Quality Monitoring')
        plt.xlabel('Time')
        plt.ylabel('AQI')
        plt.show()
 
    def demo(self):
        data = self.get_air_quality_data()
        self.plot_data(data)
 
if __name__ == "__main__":
    print("Real-Time Air Quality Monitoring Demo")

Explanation

Key Features

• Air Quality Monitoring: Monitors air quality in real-time using sensors and ML.
• Data Preprocessing: Cleans and prepares air quality data.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. Import Libraries and Setup Data

import pandas as pd
import requests
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestRegressor
import matplotlib.pyplot as plt

import pandas as pd
import requests
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestRegressor
import matplotlib.pyplot as plt

2. Data Preprocessing and Model Training Functions

def get_air_quality_data(api_url):
    response = requests.get(api_url)
    data = response.json()
    return pd.DataFrame(data)
 
def preprocess_data(df):
    return df.dropna()
 
def train_model(X, y):
    model = RandomForestRegressor()
    model.fit(X, y)
    return model

def get_air_quality_data(api_url):
    response = requests.get(api_url)
    data = response.json()
    return pd.DataFrame(data)
 
def preprocess_data(df):
    return df.dropna()
 
def train_model(X, y):
    model = RandomForestRegressor()
    model.fit(X, y)
    return model

3. CLI Interface and Error Handling

def main():
    print("Real-Time Air Quality Monitoring")
    # api_url = 'https://api.airquality.com/v1/data'
    # df = get_air_quality_data(api_url)
    # X, y = df.drop('aqi', axis=1), df['aqi']
    # model = train_model(X, y)
    print("[Demo] Monitoring logic here.")
 
if __name__ == "__main__":
    main()

def main():
    print("Real-Time Air Quality Monitoring")
    # api_url = 'https://api.airquality.com/v1/data'
    # df = get_air_quality_data(api_url)
    # X, y = df.drop('aqi', axis=1), df['aqi']
    # model = train_model(X, y)
    print("[Demo] Monitoring logic here.")
 
if __name__ == "__main__":
