Locally Installed Modules

Write a Python program to get a list of locally installed Python modules.

Sample Solution:

Python Code:

# Import the 'pkg_resources' module for working with Python packages.
import pkg_resources

# Get the list of installed packages using 'pkg_resources.working_set'.
installed_packages = pkg_resources.working_set

# Create a sorted list of strings representing installed packages and their versions.
installed_packages_list = sorted(["%s==%s" % (i.key, i.version) for i in installed_packages])

# Print each package and its version in the sorted list.
for m in installed_packages_list:
    print(m)

Explanation:

The above Python code uses the "pkg_resources" module to retrieve information about installed Python packages. It then creates a sorted list of strings representing each installed package along with its version and prints this information. The result is a list of installed packages and their versions.
