In this article, I’ll show you:

πŸ’¬ How to check the version of the Python module (package, library) ipaddress? And how to check if ipaddress is installed anyways?

These are the eight best ways to check the installed version of the Python module ipaddress:

  • Method 1: pip show ipaddress
  • Method 2: pip list
  • Method 3: pip list | findstr ipaddress
  • Method 4: library.__version__
  • Method 5: importlib.metadata.version
  • Method 6: conda list
  • Method 7: pip freeze
  • Method 8: pip freeze | grep ipaddress

Before we go into these ways to check your ipaddress version, let’s first quickly understand how versioning works in Python—you’ll be thankful to have spent a few seconds on this topic, believe me!

A Note on Python Version Numbering

πŸ’‘Python versioning adds a unique identifier to different package versions using semantic versioning. Semantic versioning consists of three numerical units of versioning information in the format major.minor.patch.

Python Version Numbering

In this tutorial, we’ll use the shorthand general version abbreviation like so:

x.y.z

Practical examples would use numerical values for x, y, and z:

  • 1.2.3
  • 4.1.4
  • 1.0.0

This is shorthand for

major.minor.patch
  • Major releases (0.1.0 to 1.0.0) are used for the first stable release or “breaking changes”, i.e., major updates that break backward compatibility.
  • Minor releases (0.1.0 to 0.2.0) are used for larger bug fixes and new features that are backward compatible.
  • Patch releases (0.1.0 to 0.1.1) are used for smaller bug fixes that are backward compatible.

Let’s dive into the meat of this article:

πŸ’¬ Question: How to check the (major, minor, patch) version of ipaddress in your current Python environment?

Method 1: pip show

To check which version of the Python library ipaddress is installed, run pip show ipaddress or pip3 show ipaddress in your CMD/Powershell (Windows), or terminal (macOS/Linux/Ubuntu).

This will work if your pip installation is version 1.3 or higher—which is likely to hold in your case because pip 1.3 was released a decade ago in 2013!!

Here’s an example in my Windows Powershell: I’ve highlighted the line that shows that my package version is a.b.c:

PS C:\Users\xcent> pip show ipaddress
Name: ipaddress
Version: a.b.c
Summary: ...
Home-page: ...
Author: ...
Author-email: ...
License: ...
Location: ...
Requires: ...
Required-by: ...

In some instances, this will not work—depending on your environment. In this case, try those commands before giving up:

python -m pip show ipaddress
python3 -m pip show ipaddress
py -m pip show ipaddress
pip3 show ipaddress

Next, we’ll dive into more ways to check your ipaddress version.

But before we move on, I’m excited to present you my new Python book Python One-Liners (Amazon Link).

If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about a single line of Python code. But it’s also an introduction to computer science, data science, machine learning, and algorithms. The universe in a single line of Python!

The book was released in 2020 with the world-class programming book publisher NoStarch Press (San Francisco).

Method 2: pip list

To check the versions of all installed packages, use pip list and locate the version of ipaddress in the output list of package versions sorted alphabetically.

This will work if your pip installation is version 1.3 or higher.

Here’s a simplified example for Windows Powershell, I’ve highlighted the line that shows the package version is 1.2.3:

PS C:\Users\xcent> pip list
Package         Version
------------- – – -------
aaa             1.2.3
...
ipaddress             1.2.3
...
zzz             1.2.3

In some instances, this will not work—depending on your environment. Then try those commands before giving up:

python -m pip list
python3 -m pip list
py -m pip list
pip3 list 

Method 3: pip list + findstr on Windows

To check the versions of a single package on Windows, you can chain pip list with findstr ipaddress using the CMD or Powershell command: pip3 list | findstr ipaddress to locate the version of ipaddress in the output list of package versions automatically.

Here’s an example for ipaddress:

pip3 list | findstr ipaddress

1.2.3

Method 4: Module __version__ Attribute

To check which version is installed of a given library, you can use the library.__version__ attribute after importing the library (package, module) with import library.

Here’s the code:

import my_library
print(my_library.__version__)
# x.y.z for your version output

Here’s an excerpt from the PEP 8 docs mentioning the __version__ attribute.

PEP 8 describes the use of a module attribute called __version__ for recording “Subversion, CVS, or RCS” version strings using keyword expansion. In the PEP author’s own email archives, the earliest example of the use of an __version__ module attribute by independent module developers dates back to 1995.”

You can also use the following one-liner snippet to run this from your terminal (macOS, Linux, Ubuntu) or CMD/Powershell (Windows):

python3 -c "import my_library; print(my_library.__version__)"

However, this method doesn’t work for all libraries, so while simple, I don’t recommend it as a general approach for that reason.

Method 5: importlib.metadata.version

The importlib.metadata library provides a general way to check the package version in your Python script via importlib.metadata.version('ipaddress') for library ipaddress. This returns a string representation of the specific version such as 1.2.3 depending on the concrete version in your environment.

Here’s the code:

import importlib.metadata
print(importlib.metadata.version('ipaddress'))
# 1.2.3

Method 6: conda list

If you have created your Python environment with Anaconda, you can use conda list to list all packages installed in your (virtual) environment. Optionally, you can add a regular expression using the syntax conda list regex to list only packages matching a certain pattern.

conda list -n xyz

Regex: How to list all packages starting with 'ipaddress'?

conda list '^ipaddress'

Method 7: pip freeze

The pip freeze command without any option lists all installed Python packages in your environment in alphabetically order (ignoring UPPERCASE or lowercase). You can spot your specific package ipaddress if it is installed in the environment.

pip freeze

Output example (depending on your concrete environment/installation):

PS C:\Users\xcent> pip freeze
aaa==1.2.3
...
ipaddress==1.2.3
...
zzz==1.2.3

You can modify or exclude specific packages using the options provided in this screenshot:

Method 8: pip freeze + grep on Linux/Ubuntu/macOS

To check the versions of a single package on Linux/Ubuntu/macOS, you can chain pip freeze with grep ipaddress using the CMD or Powershell command: pip freeze | grep ipaddress to programmatically locate the version of your particular package ipaddress in the output list of package versions.

Here’s an example for ipaddress:

pip freeze | grep ipaddress
ipaddress==1.2.3
