Team Test

Program with Output

Include a code example that demonstrates a simple program with an output.

print("Hello, world!")

Program with Input / Output

Show a program that takes user input and produces output.

name = input("Enter your name: ") print("Hello, " + name + "!") 

Program with a List

Demonstrate a program that uses a list.

fruits = ["apple", "banana", "cherry"] 
for fruit in fruits: print(fruit) 

Program with a Dictionary

Showcase a program utilizing a dictionary.

person = {"name": "John", "age": 30, "city": "New York"} 
print(person["name"]) 

Program with Iteration

Provide an example of a program that uses iteration (e.g., a for loop).

for i in range(5): 
    print(i) 

Program with a Function

Create a function that performs a mathematical or statistical calculation.

def calculate_average(numbers): 
    total = sum(numbers) 
    return total / len(numbers)
numbers = [10, 20, 30, 40, 50] 
average = calculate_average(numbers) 
print("Average:", average) 

Program with a Selection/Condition

Include a program with a selection or condition (e.g., if/else statement).

x = 10 
if x > 5: 
    print("x is greater than 5") 
else: 
    print("x is not greater than 5") 

Debugging

Explain the overall purpose of this program, summarizing what you’ve covered.

# Initial version with an error
x = 10
y = 0
try:
    result = x / y
except ZeroDivisionError as e:
    print("Error:", e)

# Debugging steps to fix the error
try:
    if y == 0:
        raise ValueError("y cannot be zero")
    result = x / y
except ValueError as e:
    print("Error:", e)


# Corrected version
def divide(x, y):
    if y == 0:
        raise ValueError("y cannot be zero")
    return x / y
try:
    result = divide(x, y)
except ValueError as e:
    print("Error:", e)
else:
    print("Result:", result)

# Debugging steps to fix the error 
try: 
    if y == 0: 
        raise ValueError("y cannot be zero") 
    result = x / y 
except ValueError as e: 
    print("Error:", e) 

The code block above demonstrates the steps to fix the error by checking for a zero division condition and raising a ValueError with a meaningful error message.

# Corrected version:
def divide(x, y): 
    if y == 0: 
        raise ValueError("y cannot be zero") 
    return x / y 
try: 
    result = divide(x, y) 
except ValueError as e: 
    print("Error:", e) 
else: 
    print("Result:", result) 

The code block above provides the corrected version of the code using a divide function that includes the fix. It also includes error handling to catch and handle any exceptions, and it prints the result if there are no errors.

Program with Purpose

import requests

def get_weather(api_key, city):
    base_url = "http://api.openweathermap.org/data/2.5/weather"
    params = {
        "q": city,
        "appid": api_key,
        "units": "metric",  # Change to "imperial" for Fahrenheit
    }

    response = requests.get(base_url, params=params)

    if response.status_code == 200:
        weather_data = response.json()
        temperature = weather_data["main"]["temp"]
        description = weather_data["weather"][0]["description"]
        print(f"Weather in {city}:")
        print(f"Temperature: {temperature}°C")
        print(f"Description: {description.capitalize()}")
    else:
        print("Error fetching weather data. Please check your city name and API key.")

def main():
    api_key = "23041de8a421616f9c9c808ce3ea80d9"  # Replace with your OpenWeatherMap API key
    city = input("Enter your city: ")
    get_weather(api_key, city)

if __name__ == "__main__":
    main()

Conclusion

Provide a concluding statement, summarizing the key concepts and skills learned in the notebook.
