    import requests
import json
from dotenv import load_dotenv
import os</li>
</ol>

<p>load_dotenv()

class SimpleAgent:
def <strong>init</strong>(self, name):
self.name = name
self.api_key = os.getenv("WEATHER_API_KEY")  Store your API key in a .env file

def fetch_weather(self, city):
"""Fetches current weather for a given city."""
url = f"http://api.openweathermap.org/data/2.5/weather?q={city}&appid={self.api_key}&units=metric"
try:
response = requests.get(url)
response.raise_for_status()  Raise an exception for bad status codes
data = response.json()
return data
except requests.exceptions.RequestException as e:
print(f"Error fetching weather: {e}")
return None

def process_and_display(self, city):
"""Processes the weather data and displays a summary."""
weather_data = self.fetch_weather(city)
if weather_data:
temp = weather_data['main']['temp']
description = weather_data['weather'][bash]['description']
print(f"Weather in {city}: {temp}°C, {description}")
else:
print(f"Could not retrieve weather for {city}.")

if <strong>name</strong> == "<strong>main</strong>":
agent = SimpleAgent("WeatherBot")
agent.process_and_display("London")

}
df = pd.DataFrame(data)

Features (X) and Target (y)
X = df[['YearsExperience']]
y = df['Salary']

Split the data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

Create and train the model
model = LinearRegression()
model.fit(X_train, y_train)

Make predictions
y_pred = model.predict(X_test)

Evaluate the model
mse = mean_squared_error(y_test, y_pred)
r2 = r2_score(y_test, y_pred)
print(f"Mean Squared Error: {mse}")
print(f"R-squared Score: {r2}")

Visualize the results
plt.scatter(X, y, color='blue', label='Actual Data')
plt.plot(X, model.predict(X), color='red', linewidth=2, label='Regression Line')
plt.xlabel('Years of Experience')
plt.ylabel('Salary')
plt.title('Linear Regression Model')
plt.legend()
plt.show()
