Checking Installed Packages in Python
Checking Installed Packages in Python
Managing packages in Python is vital for any developer. Whether you are tracking dependencies or troubleshooting bugs, knowing how to check installed packages is crucial.
Here’s a simple command-line method to check installed packages using pip:
> pip list
This command lists all the packages installed in your Python environment along with their versions.
Additionally, you can use the following Python script to programmatically check installed packages:
import pkg_resources
installed_packages = pkg_resources.working_set
for package in installed_packages:
print(package)
This script iterates through the installed packages and prints each package’s information.
Ensuring you have the right packages installed is fundamental to efficient Python development. Whether you are starting a new project or maintaining an existing one, regularly checking your installed packages is a good practice.
