Description

Session Goal

The session aimed to enhance file handling capabilities in Python, focusing on reading, analyzing, and extracting data from files, as well as addressing errors in data processing pipelines.

Key Activities

• Implemented code to read a Python file and extract its length and content using pathlib.
• Developed a script to search for patterns in report files using regular expressions and the glob module.
• Checked file existence and size using Python’s pathlib library.
• Extracted data from reports by reading text and applying regular expressions to identify patterns.
• Patched a function to process ‘renta’ data, allowing for modifications in data processing loops.
• Resolved a KeyError in the load_reports_folder function by implementing a safe fix to handle missing ‘Box’ columns in renta CSV files.

Achievements

• Successfully implemented robust file handling techniques in Python.
• Enhanced data extraction methods using regular expressions.
• Improved error handling in data processing pipelines, ensuring resilience against missing data columns.

Pending Tasks

• Further testing of the patched renta block function to ensure compatibility with all data variations.
