This function, find_highest_borrowing_member, begins with a check for an empty input, specifically for the parameter total_durations. Here's a detailed explanation of what the provided code does:

1. Input Parameter: The function takes one argument, total_durations, which is expected to be some form of collection (like a list, dictionary, etc.). However, the exact structure isn't specified in the code snippet.

2. Handle Empty Input: The line if not total_durations: checks if total_durations is empty, None, or evaluates to False.

   • If the condition evaluates to True (i.e., the input is empty), the function immediately returns a tuple ([], 0):
     • An empty list ([]), possibly representing no members.
     • A numerical value 0, which could signify no duration or activity.

3. Function Partial Purpose: In broader terms (based on the name find_highest_borrowing_member), it seems that the function will eventually determine which "member" has the highest borrowing duration. However, since the rest of the code is not provided, we only know that the function handles the case when the input total_durations is empty by returning default values.

This code segment ensures that the function gracefully exits with default values if no data is provided.
