What is PIP?

PIP is Python's package manager. It installs libraries from the Python Package Index (PyPI).

# Run in terminal (not in Python):
# pip install requests
# pip install numpy pandas

Common commands

pip install, pip uninstall, pip list, pip freeze, pip show.

# pip install requests     — install a package
# pip uninstall requests   — remove it
# pip list                 — show installed
# pip freeze > requirements.txt

Try it yourself

Run the example below. Edit it and see what changes.

main.py

# PIP is a terminal tool, not Python code.
# Here's how you'd use an installed package:
import json
data = json.dumps({"pip": "awesome"})
print(data)
