Checking Python Package Version via Command Line

Python package management is essential for maintaining and updating Python libraries. To check the version of a Python package via the command line, we have several handy tools at our disposal. In this blog post, we will explore various methods to efficiently check the versions of Python packages installed on your system.

Using pip Command:

The simplest way to check the version of a Python package is by using the pip command. To check the version of a specific package, you can run:

pip show

This command will display detailed information about the package, including its version number.

Inspecting module attributes:

Another method to check package versions is by directly inspecting the module attributes within Python itself. By importing the desired package and accessing its __version__ attribute, you can retrieve the version information.

“`python
import package_name
print(package_name.__version__)
“`

Using pkg_resources:

The pkg_resources module, provided by setuptools, offers additional functionality for retrieving package metadata like version numbers.

“`python
import pkg_resources
version = pkg_resources.get_distribution(“package_name”).version
print(version)
“`

Wrapping Up:

These methods allow you to swiftly verify the versions of Python packages installed on your system, ensuring you are up-to-date with the latest features and bug fixes. Stay informed about package dependencies to maintain a healthy and efficient Python environment.
