Python Modulefinder Module
The modulefinder module provides a ModuleFinder class that can be used to determine the set of modules imported by a script. modulefinder.py can also be run as a script, giving the filename of a Python script as its argument, after which a report of the imported modules will be printed.
Importing the Module

To use modulefinder programmatically, you instantiate the ModuleFinder class and run a script against it.
from modulefinder import ModuleFinder
import os
# Create a dummy script for demonstration
script_name = "myscript.py"
with open(script_name, "w") as f:
f.write("import os\nimport sys\nimport math\n")
finder = ModuleFinder()
finder.run_script(script_name)
print('Loaded modules:')
for name, mod in finder.modules.items():
print(f"{name}: {mod}")
print('-'*20)
print('Modules not imported:')
print('\n'.join(finder.badmodules.keys()))
# Clean up
