Step 3: Create the initial product generator
Step 4: Save the progress to a file
To save the current state of the product generator, we can use the pickle module to serialize the generator's state and data to a file.
Step 5: Resume the product generation
To resume the product generation from where it left off, you need to load the saved generator and continue iterating.
