Session Goal

The goal of this session was to enhance and modularize functions for processing financial ledger data using Python and Pandas, focusing on filtering and time-series analysis.

Key Activities

  • Developed a Python function to extract rent-related records from a financial ledger DataFrame, improving code modularity and readability.
  • Created the get_from_ledger function to filter a Pandas DataFrame based on specified criteria using predefined masks, with examples and component explanations.
  • Updated the get_from_ledger function to streamline logic for better flexibility and maintainability.
  • Enhanced the compute_transaction_series function for flexible ledger analysis, incorporating time-series data computation with cumulative sums and conflict-free column naming.
  • Addressed the SettingWithCopyWarning in Pandas by ensuring modifications are made on a DataFrame copy, improving data processing reliability.

Achievements

  • Successfully modularized and improved the filtering logic for financial ledger data processing.
  • Enhanced functions for better flexibility, maintainability, and error handling.

Pending Tasks

  • Further testing and validation of the updated functions in diverse scenarios to ensure robustness and accuracy.
