How do I check the versions of Python modules?
I installed the Python modules construct and statlib using setuptools:
sudo apt-get install python-setuptools
sudo easy_install statlib
sudo easy_install construct
How do I check package version python from the command line for these modules?
I’ve been working with Python modules for a while, and the simplest way to check package version Python is by using the pip show command. You can use it directly from the command line like this:
pip show construct
pip show statlib
This will give you detailed information about the installed package, including its version. It’s a quick way to verify what version of the module you’re working with.
Netra’s suggestion is great! But if you’re juggling multiple versions of Python or working within different environments, you might want to make sure you’re checking the version for the correct Python interpreter. Instead of just using the regular pip, you can use a command that directly links to the specific Python version you’re working with. This ensures that the version you see corresponds to the right environment, especially if you have more than one version of Python installed. It’s a handy trick to avoid confusion when managing different setups.
Good point, Ian! And if you’re already inside a Python script or interpreter and just want to quickly check package version Python without leaving your environment, you can do something like this:
import construct
import statlib
print(construct.__version__)
print(statlib.__version__)
This method works well if the modules expose their version as an attribute, which most good packages do. It’s a neat trick to check on the fly, especially when you’re debugging or testing in a Python environment.
