Final answer:
To check the version of a Python package, use the 'pip show' command or print the package's '__version__' attribute within a Python script.
Step-by-step explanation:
To check a package version in Python, you can use the pip command-line tool or within a Python script by importing the package and printing its version attribute, which is commonly __version__.
For example, to check the version of a package via pip, you can use the command pip show packagename in your terminal or command prompt. This will display detailed information about the package, including the version number. Alternatively, if you are already within a Python script or interpreter, you can check the package version with the following code:
import packagename
print(packagename.__version__)
This is a straightforward method and works with most Python packages, as the version attribute is a widely-used convention.
