Installation and Setup

pip is included by default with CPython distributions since version 3.4. To ensure you have the latest versions of pip, you can run:

$ python -m pip install --upgrade pip

If pip is not available in your Python installation, then you can run the following:

$ python -m ensurepip --upgrade

Key Features

• Installs Python packages and their required dependencies from PyPI or other package indices.
• Supports installing packages from various sources, including Git repositories, ZIP files, wheel files, and local directories.
• Enables users to specify exact package versions or define version ranges.
• Facilitates environment replication by installing dependencies listed in a requirements.txt file.
• Provides commands to list installed packages (pip list), view package metadata (pip show), and upgrade or uninstall existing packages.

Usage

Install the latest version of a package:

$ python -m pip install package-name

Install specific versions of a package:

$ # Exact version: ==
$ python -m pip install "package-name==version"

$ # At least version: >=
$ python -m pip install "package-name>=version"

$ # Less than version: <
$ python -m pip install "package-name<version"

Capture the environment:

$ python -m pip freeze > requirements.txt

Replicate the environment:

$ python -m pip install -r requirements.txt
