Description

Session Goal

The session aimed to review and enhance data processing logic, focusing on contract enforcement, particularly in currency safety, view consistency, and binning rules.

Key Activities

• Conducted a critical review of data processing contracts, identifying issues related to currency safety and view consistency.
• Developed Python code for financial data processing using pandas, including CSV loading, data normalization, and pivot view generation.
• Demonstrated various Python techniques for file handling, text processing, and code analysis, including reading file contents, extracting function definitions, and searching for specific keywords.
• Implemented a new iteration of views.py with enhanced contract enforcement, addressing currency handling and observability.

Achievements

• Clarified and critiqued existing data processing contract decisions, providing actionable fixes.
• Successfully developed and tested Python scripts for financial data processing and file operations.
• Enhanced views.py with improved contract enforcement, ensuring better currency handling and data validation.

Pending Tasks

• Implement upstream fixes in core_timeseries.py and models.py to prevent blank currency issues as recommended.
• Further exploration of time series data aggregation and manipulation queries to optimize currency normalization and data frame operations.
