What tools and libraries do you use when programming in Python?

When programming in Python, I often use the following tools and libraries:

• Standard library: os, sys, datetime, collections, itertools — for basic tasks.
• requests — for working with HTTP requests.
• pandas and numpy — for data processing and analysis.
• matplotlib and seaborn — for data visualization.
• flask or django — for web development.
• pytest — for writing and running tests.
• virtualenv or venv — for environment isolation.

Example of using requests to fetch data from an API:

import requests

response = requests.get('https://api.example.com/data')
if response.status_code == 200:
    data = response.json()
    print(data)
