Along with the creation of Segment objects, analysts also need a way to easily access the UserALE logs associated with each Segment. Distill's Segmentation package allows analysts to do this through the use of the write_segment function.
The write_segment function creates a nested dictionary of segment names to UIDs which then map to individual logs (i.e result['segment_name'][uid] --> log). This assists with easy iteration over defined Segment objects.
# Sorted dictionary of UserALE logs sorted_dict # List of segment names segment_names = ["segment1", "segment2"] # Time tuples start_end_vals = [(start_time_1, end_time_1), (start_time_2, end_time_2)] # Write Segments segments = distill.write_segment(sorted_dict, segment_names, start_end_vals)
The above code looks similar to the create_segments example usage, however, rather than returning a Segments object, this code will create a dictionary of segment names to UIDs to individual UserALE logs.
Since Segments objects support list comprehensions, the usage of the write_segment functon after curating a collection of Segment objects is simple. Below is some example code that shows how this can be done with a Segments object:
# Sorted dictionary of UserALE logs sorted_dict # Segments object segments # Create list of segment names segment_names = [segment.segment_name for segment in segments] # Create list of start and end values start_end_vals = [segment.start_end_val for segment in segments] written_segments = distill.write_segments(sorted_dict, segment_names, start_end_vals)
