In Python, managing packages is an essential part of the development process. Knowing the version of the package that is currently installed can help us to ensure compatibility and debug issues effectively in our python code. In this article, we will explore methods to determine the version of packages installed in our current working python environment.

Methods to Check Version of Installed Python Modules

Method 1: Using pip show command

The pip show command provides detailed information about specific package, including its version. To use this method, we need to follow these steps:

• Open terminal or command prompt and type the following command

pip show package_name

Example

Method 2: Using __version__ attribute

Many python packages store their version number in ‘__version__’ attribute. We can access this attribute to find the version of the installed package. Steps to follow this method are

• Open python interpreter or script (in command prompy by typing command python)
• Next is to import the package and using __version__ attribute we can print the version of imported packkage as follows

import pandas as pd

print(pd.__version__)

Method 3: Using pip list command

Using this method we can get the versions of all the packages installed in current python working environment. Steps to achieve this method are

• Open Terminal or command prompt
• Type the following command and hit enter

pip list

Conclusion

Knowing how to check the version of instaled packages in python is crucial for maintainig a stable development environment. The methods discussed above provide ways to accomplish this, whether we prefer using command -line tools or python. Choose the method taht best fits our workflow and ensure our projects run smoothly by keeping track of installed package versions.
