Download and Install Python third-party library using pip command

Download and Install Python third-party library using pip command

pip is the package installer for Python and is used to install and manage third-party libraries. In this tutorial, we will learn how to use the pip command to download and install Python third-party libraries.

  • Ensure pip is installed:

Before you can use pip, you need to ensure that it is installed. Most Python installations come with pip by default. You can check if pip is installed and see its version by running the following command in your terminal or command prompt:

pip --version

If pip is not installed or you need to upgrade it, follow the instructions on the official pip documentation.

  • Install a third-party library:

To install a third-party library using pip, you can use the install command followed by the name of the library you want to install. For example, if you want to install the requests library, run the following command:

pip install requests

This command downloads and installs the latest version of the requests library and its dependencies.

  • Install a specific version of a library:

If you need a specific version of a library, you can use the == operator followed by the desired version number. For example, to install version 2.25.1 of the requests library, run the following command:

pip install requests==2.25.1
  • Upgrade an installed library:

To upgrade an already installed library to the latest version, you can use the --upgrade or -U option. For example, to upgrade the requests library, run the following command:

pip install --upgrade requests
  • Uninstall a library:

To uninstall a library, you can use the uninstall command followed by the name of the library. For example, to uninstall the requests library, run the following command:

pip uninstall requests

You will be prompted to confirm the uninstallation. Type y and press Enter to proceed.

  • List installed libraries:

To list all installed libraries and their versions, you can use the list command:

pip list

In summary, the pip command is used to download and install Python third-party libraries. You can use pip to install, upgrade, uninstall, and list libraries and their versions. Before using pip, make sure it is installed and up-to-date by checking its version with pip --version.
