Python PIP

Learn how to use PIP (Python Package Installer) to install and manage Python packages.

What is PIP?

PIP is a package manager for Python packages, or modules if you like.

Note: If you have Python version 3.4 or later, PIP is included by default.

What is a Package?

A package contains all the files you need for a module.

Modules are Python code libraries you can include in your project.

Check if PIP is Installed

Navigate your command line to the location of Python's script directory, and type the following:

Check PIP version:

pip --version

If PIP is installed, you will see something like this:

pip 23.3.1 from /usr/local/lib/python3.11/site-packages/pip (python 3.11)

Install PIP

If you do not have PIP installed, you can download and install it from this page: https://pypi.org/project/pip/

Download a Package

Downloading a package is very easy.

Open the command line interface and tell PIP to download the package you want.

Example - Download a package named "camelcase":

pip install camelcase

Now you have downloaded and installed your first package!

Using a Package

Once the package is installed, it is ready to use.

Import the "camelcase" package into your project.

Example - Import and use "camelcase":

import camelcase

c = camelcase.CamelCase()

txt = "hello world"

print(c.hump(txt))

Find Packages

Find more packages at https://pypi.org/.

You can also search for packages using pip:

Search for packages (deprecated in newer versions):

# Note: pip search was deprecated
# Use the PyPI website instead: https://pypi.org/

Remove a Package

Use the uninstall command to remove a package:

Example - Uninstall the package named "camelcase":

pip uninstall camelcase

The PIP Package Manager will ask you to confirm that you want to remove the camelcase package:

Uninstalling camelcase-0.2:
  Would remove:
    /usr/local/lib/python3.11/site-packages/camelcase/*
Proceed (y/n)?

Press y and the package will be removed.

List Packages

Use the list command to list all the packages installed on your system:

Example - List installed packages:

pip list

Result:

Package    Version
---------- -------
camelcase  0.2
mysql-connector-python 8.0.29
pip        23.3.1
setuptools 65.5.0

Show Package Information

Use the show command to display information about a specific package:

Example - Show package information:

pip show camelcase

Result:

Name: camelcase
Version: 0.2
Summary: Convert string into camelCase

Advanced PIP Commands

Install Specific Version

# Install specific version
pip install django==4.2.0

# Install minimum version
pip install django>=4.0.0

# Install version range
pip install "django>=4.0.0,<5.0.0"

Upgrade Packages

# Upgrade a package to latest version
pip install --upgrade django

# Upgrade pip itself
pip install --upgrade pip

# Show outdated packages
pip list --outdated

Install from Requirements File

# Install packages from requirements.txt
pip install -r requirements.txt

# Generate requirements file
pip freeze > requirements.txt

Working with Requirements Files

Requirements files are used to specify project dependencies:

Example - requirements.txt file:

# Web framework
django==4.2.7
djangorestframework==3.14.0

# Database
psycopg2-binary==2.9.7

# Development tools
pytest==7.4.3
black==23.11.0
flake8==6.1.0

# Data processing
pandas>=1.5.0,<2.0.0
numpy>=1.24.0

# Optional dependencies
requests[security]>=2.31.0

Install from requirements file:

pip install -r requirements.txt

Generate requirements file from current environment:

pip freeze > requirements.txt

Virtual Environments

Virtual environments help manage dependencies for different projects:

Create and use virtual environment:

# Create virtual environment
python -m venv myproject_env

# Activate virtual environment (Windows)
myproject_env\Scripts\activate

# Activate virtual environment (macOS/Linux)
source myproject_env/bin/activate

# Install packages in virtual environment
pip install django requests

# Deactivate virtual environment
deactivate

# Remove virtual environment
rm -rf myproject_env  # Linux/macOS
rmdir /s myproject_env  # Windows

PIP Configuration

Configure PIP behavior with configuration files:

Example - pip.conf (Linux/macOS) or pip.ini (Windows):

[global]
timeout = 60
index-url = https://pypi.org/simple/
trusted-host = pypi.org
               pypi.python.org
               files.pythonhosted.org

[install]
upgrade = true
user = false

Configuration file locations:

# Global configuration
# Linux/macOS: /etc/pip.conf
# Windows: C:\ProgramData\pip\pip.ini

# User configuration
# Linux/macOS: ~/.pip/pip.conf or ~/.config/pip/pip.conf
# Windows: %APPDATA%\pip\pip.ini

# Virtual environment configuration
# $VIRTUAL_ENV/pip.conf

SSL certificate errors:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org package_name

Clear pip cache:

pip cache purge

Force reinstall:

pip install --force-reinstall package_name

Install from source:

pip install --no-binary :all: package_name

Verbose output for debugging:

pip install -v package_name

Best Practices

Always use virtual environments for projects
Pin package versions in requirements.txt for reproducible builds
Regularly update packages to get security fixes
Use pip check to verify dependency compatibility
Keep requirements.txt files up to date
Use --user flag for personal installations
Consider using tools like pipenv or poetry for advanced dependency management

Everyday pip Commands

Command	Does
`pip install requests`	Install a package
`pip install requests==2.31.0`	Install a specific version
`pip install --upgrade requests`	Upgrade to the latest
`pip uninstall requests`	Remove a package
`pip list`	List installed packages
`pip show requests`	Details about one package

If pip is not found, run it through Python: python -m pip install requests (use py -m pip on Windows). This guarantees you install into the Python you are actually running.

requirements.txt: Reproducible Installs

Pin your project's dependencies in a file so anyone can recreate the exact environment.

# save current environment
pip freeze > requirements.txt

# requirements.txt might contain:
# requests==2.31.0
# pandas==2.2.0

# install everything from it
pip install -r requirements.txt

Try It Yourself

Exercise 1: Install the requests library and confirm it is installed.

Show solution

pip install requests
pip show requests     # prints name, version, location

Exercise 2: Freeze your current packages into a requirements file.

Show solution

pip freeze > requirements.txt

Key Takeaways

pip installs packages from the Python Package Index (PyPI).
Use python -m pip to target the right interpreter.
Pin dependencies in requirements.txt; install with -r.
Always install into a virtual environment (next chapter for that topic).

📘 Real-World Deep Dive

<code>pip</code> is the default Python package manager and the first thing every Python project needs to know. Knowing the modern <code>pyproject.toml</code>-driven workflow, the resolver, and the editable-install pattern is the difference between a working setup and a slow week of debugging.

Real-Life Scenario

A reproducible install flow: read the lockfile, install only what is in it, then sanity-check that the entrypoint script works.

Real-Life Example

import subprocess, sys
from pathlib import Path

LOCK = Path("requirements.txt")

def pip(*args: str) -> None:
    cmd = [sys.executable, "-m", "pip", "--disable-pip-version-check", *args]
    print("$ " + " ".join(cmd))
    subprocess.run(cmd, check=True)

if not LOCK.exists():
    print(f"missing {LOCK}; aborting")
    sys.exit(1)

pip("install", "--upgrade", "pip", "setuptools", "wheel")
pip("install", "-r", str(LOCK))

# Verify
import importlib.metadata as md
for dist in ["fastapi", "uvicorn", "pydantic"]:
    try:
        print(f"{dist:>10}: {md.version(dist)}")
    except md.PackageNotFoundError:
        print(f"{dist:>10}: NOT INSTALLED")

Expected Output

$ python -m pip --disable-pip-version-check install -r requirements.txt
Successfully installed ...
   fastapi: 0.115.0
   uvicorn: 0.30.5
   pydantic: 2.9.2

Common mistakes

Always invoke python -m pip rather than bare pip — guarantees the right interpreter.
Installing into the system Python breaks system tooling; always use a virtualenv.
--no-cache-dir is fine in CI but slows local dev iterations.

🚀 Performance & Best Practices

Use --require-hashes for supply-chain safety in CI.
Use --no-deps when installing custom-built wheels.
uv pip install is 10–100× faster than pip install for big projects.

🧪 Try It Yourself

Compare pip-compile vs. uv pip compile outputs on the same source.
Write a test that fails if any requirements.txt package is unpinned.
Build a wheel for an in-repo package with python -m build and install with --no-deps.
