Python PIP - GeeksforGeeks

Last Updated : 12 Jul, 2025

In this article, we will discuss what is PIP, and how to install, upgrade, and uninstall packages using Python PIP. So before starting and using it, let us understand what is a Python PIP.

Package refers to a distribution of Python code that includes one or more modules or libraries. These packages are typically published on the Python Package Index (PyPI) and can be easily installed using pip. Python packages may contain modules, sub-packages, and additional resources such as documentation and data files.

Python PIP is the package manager for Python packages. We can use PIP to install packages that do not come with Python. The basic syntax of PIP commands in the command prompt is: 

pip 'arguments'

Python PIP comes pre-installed on 3.4 or older versions of Python. To Check if PIP is Installed or not type the below command in the terminal.

pip --version

This command will tell the version of the Pip if it is already installed in the system.

We can install additional packages by using the Python pip install command. Let's suppose we want to install the Numpy using PIP. We can do it using the below command.

Syntax: 

pip install numpy

Example 1: When the required package is not installed. 

Example 2: When the required package is already installed. 

We can also install the package of a specific version by using the below command.

Syntax: 

pip install package_name==version

This will install the package with the specified version

We can use the Python pip show command to display the details of a particular package. 

Syntax: 

pip show numpy

Example: 

Note: 

• Requires column shows the dependencies required by the NumPy package
• Required by shows the packages that require NumPy

The Python pip list command displays a list of packages installed in the system. 

Syntax: 

pip list

Example: 

The Python pip uninstall command uninstalls a particular existing package. 

Syntax: 

pip uninstall numpy

Example: 

Note: The PIP uninstall command does not uninstall the package dependencies. If you want to remove the dependencies as well then you can see the dependencies using the pip show command and remove each package manually.

We can search for a particular existing package using the Python pip search command. 

Syntax: 

pip search numpy

Example: 

Let's suppose you want more than one package then instead of installing each package manually, you can install all the modules in a single go. This can be done by creating a requirements.txt file. Let's suppose the requirements.txt file looks like this:

Syntax: 

pip install -r requirements.txt

Example: 

The Python pip freeze command is used to list packages that don't come pre-installed with Python. 

Syntax: 

pip freeze

Example: 

Python pip list --outdated command is used to list all the packages that are outdated. This command cross-checks the installed package information with the PIP repository.

Syntax:

pip list --outdated

Example:

Python pip install --user --upgrade is used to update a package.

Syntax:

pip install --user --upgrade package_name

Example:

We can also upgrade any package to a specific version using the below command.

pip install --user --upgrade package_name==version

the Python pip install --user command is used to downgrade a package to a specific version.

Syntax:

pip install --user package_name==version

Example:
