What is PIP?

PIP stands for “Pip Installs Packages” (or sometimes humorously, “Pip Installs Python”).
It is the official package manager for Python.

PIP allows you to install, update, and remove external libraries and dependencies that are not included in Python’s standard library.

Why You Need PIP

Python’s standard library is powerful, but many features (like web frameworks, data analysis, or machine learning tools) are provided by third-party packages.

PIP helps you:

Install new packages from the Python Package Index (PyPI)
Keep your libraries up to date
Manage dependencies for your Python projects

Basic Commands

Task	Command	Example
Check pip version	`pip --version`	→ `pip 24.0 from ...`
Install a package	`pip install package_name`	`pip install requests`
Uninstall a package	`pip uninstall package_name`	`pip uninstall requests`
Upgrade a package	`pip install --upgrade package_name`	`pip install --upgrade numpy`
List installed packages	`pip list`	shows all installed packages
Show package info	`pip show package_name`	`pip show pandas`
Save dependencies	`pip freeze > requirements.txt`	generates a list of installed packages
Install from file	`pip install -r requirements.txt`	installs everything in the file

Example: Installing and Using a Package

pip install requests

Then in Python:

import requests

response = requests.get("https://api.github.com")
print(response.status_code)

Output:

Where Does PIP Get Packages From?

By default, PIP installs packages from PyPI (Python Package Index) →
🔗 https://pypi.org/

Example: when you run

pip install flask

it downloads Flask from PyPI and installs it in your Python environment.

Virtual Environments and PIP

Usually, developers use virtual environments (e.g., venv) to isolate dependencies for each project.

Example:

python -m venv myenv
myenv\Scripts\activate     # (Windows)
source myenv/bin/activate  # (Mac/Linux)

pip install django

Now Django is installed only inside this environment, not globally.

Summary

Concept	Description
PIP	Python’s package manager
Use	Install, update, and manage third-party libraries
Source	Downloads from PyPI.org
Command Example	`pip install numpy`
Works Best With	Virtual environments (`venv`, `conda`)
