The pip freeze method is useful when you want to quickly check the version of all the installed modules in your environment. To use pip freeze, simply type “pip freeze” in your Command Prompt or Terminal and hit enter.

The output will display a list of installed packages, along with their version numbers.

2) Using pip list

Another way to determine the version of your installed Python modules is by using the “pip list” command. This will return a more concise list of installed modules and their versions, along with their distribution names and installation locations.

To use pip list, simply type “pip list” in your Command Prompt or Terminal and hit enter. The output will display a list of installed packages, along with their version numbers, distribution names, and installation locations.

3) Using pip show

If you want to determine the version of a specific Python module, you can use the “pip show” command. This will display detailed information about the specified module, including its version number, dependencies, and file locations.

To use pip show, simply type “pip show [module name]” in your Command Prompt or Terminal and hit enter. Replace “[module name]” with the name of the module you want to check the version of.

4) Using package.__version__ function

If you are working with a Python package, you can determine its version by using the “__version__” function. This is a built-in function in most Python packages that will return the package’s version number.

To use the __version__ function, simply type “[package name].__version__” in your script or interpreter. Replace “[package name]” with the name of the package you want to check the version of.

5) Using importlib from python

Lastly, you can determine the version of a specific Python module using the “importlib” library. This is a standard library in Python that allows you to inspect and interact with imported modules, including their metadata.

To use importlib to determine the version of a module, simply type “import [module name]; print([module name].__version__)” in your script or interpreter. Replace “[module name]” with the name of the module you want to check the version of.

Why is it Important to Keep Python Modules Up-to-date? Now that you know how to determine the version of installed Python modules, it is equally important to understand why it is important to keep them up-to-date.
