Expected Output:

import random

def guess_number():
    number = random.randint(1, 100)
    guess = 0
    while guess != number:
        guess = int(input("Guess a number between 1 and 100: "))
        if guess < number:
            print("Too low!")
        elif guess > number:
            print("Too high!")
    print("You guessed it!")

How to Do It: Start with def guess_number(): and let Copilot fill in the rest.

6. Basic Web Scraper

What to Do: Scrape a website for data.

Expected Output:

import requests
from bs4 import BeautifulSoup

def scrape_website(url):
    response = requests.get(url)

    return soup.title.text

How to Do It: Type def scrape_website(url): and let Copilot guide you.

7. Simple API Call

What to Do: Make a simple API call to fetch data.

Expected Output:

import requests

def fetch_data(api_url):
    response = requests.get(api_url)
    return response.json()

How to Do It: Start with def fetch_data(api_url): and watch the magic happen.

8. Basic Markdown to HTML Converter

What to Do: Convert Markdown text to HTML.

Expected Output:

import markdown

def convert_markdown(md_text):

9. Simple File Reader

What to Do: Read a text file and print its contents.

Expected Output:

def read_file(file_path):
    with open(file_path, 'r') as file:
        return file.read()

How to Do It: Start with def read_file(file_path): and see Copilot’s suggestions.

10. Basic Email Sender

What to Do: Send a simple email using SMTP.

Troubleshooting Common Issues

1. Copilot Doesn’t Suggest Anything: Make sure the extension is enabled and you’re connected to the internet.
2. Incorrect Suggestions: Always review Copilot’s suggestions. It’s not perfect and can make mistakes.
3. Limited Language Support: Copilot works best with popular languages. If you're coding in a niche language, you might not get optimal suggestions.

What's Next?

Once you’ve completed these ten programs, consider building upon them. Add features, refactor your code, or even try creating a small project that combines several of these programs. The real learning begins when you start modifying and expanding your code.

Conclusion

Using GitHub Copilot to write your first ten programs is a practical way to get started with coding. It’s not just about getting the code written; it’s about learning how to think like a programmer. So, dive in, experiment, and let Copilot assist you on your journey. Remember, the best way to learn coding is by doing!
