# Installing Python packages with pip


Here are the basics you need to know about installing Python packages.

Apart from the built-in modules that come by default with the Python installation (the Standard Library), you need to install third-packages packages to be able to use them in your code (and of course import them).

You do so with a package manager. Perhaps the most widely known is **pip**, but there are other options like **poetry** or **uv**.

You can check more information about Python packages at [pypi.org](http://pypi.org)

Here's a quick list of common use cases:

`➡ pip install pandas # installs the package and its dependencies`

`➡ pip uninstall pandas # removes the package`

`➡ pip install --upgrade pandas # upgrades a package`

`➡ pip list # lists installed packages`

`➡ pip freeze > requirements.txt # saves the list of installed packages to a file so you can recreate the environment with the same packages next time you need it`
