🕒 00:05–01:30
🏷️ Labels: Python, CSV, Dataframe, Error Handling, Pandas
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal: The session aimed to enhance Python scripts for processing CSV files and manipulating DataFrames, focusing on file handling, data transformation, and error management.

Key Activities:

  • Developed Python code for CSV transformation, including renaming output files based on specific criteria.
  • Reworked a function to modify file paths and ensure target directories exist, demonstrating usage in a loop with CSV files.
  • Updated functions for transforming file paths and names, extracting tags, and formatting output correctly.
  • Implemented CSV file processing using pandas, grouping data by specific columns and saving results.
  • Applied string manipulation in DataFrame columns using str.zfill() to add leading zeros.
  • Corrected string modification code and addressed an AttributeError by ensuring inputs are strings.
  • Created a mapping dictionary to correct spelling discrepancies in datasets.

Achievements:

  • Successfully refactored and enhanced Python code for CSV and DataFrame operations.
  • Improved error handling and data processing techniques.

Pending Tasks:

  • Further testing of the updated functions in different scenarios to ensure robustness.
  • Integration of these functions into larger data processing pipelines.
