Exploring Popular Libraries

# 1. requests — HTTP library (the most downloaded package!)
# import requests
# response = requests.get("https://api.github.com")
# print(response.status_code)
# print(response.json())

# 2. click — Beautiful CLI interfaces
# import click
# @click.command()
# @click.option('--name', prompt='Your name')
# def hello(name):
#     click.echo(f'Hello {name}!')

# 3. python-dotenv — Environment variables
# from dotenv import load_dotenv
# load_dotenv()
# api_key = os.getenv("API_KEY")

# 4. Rich — Beautiful terminal output
# from rich import print
# from rich.table import Table
