🏷️ Labels: Python, Pandas, Data Visualization, Timezone, Optimization
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to enhance data processing and visualization techniques using Python, focusing on handling date ranges, timezone issues, and optimizing DataFrame operations.

Key Activities

  • Developed a Python function to process data files by date range, employing Pandas for data manipulation.
  • Created histograms for date columns in DataFrames using Matplotlib, including enhancements for clarity with titles and labels.
  • Addressed timezone-related errors in data processing, ensuring datetime objects are timezone-aware and resolving invalid comparison errors in Pandas.
  • Optimized DataFrame operations by replacing iterrows with apply and concat for improved performance.
  • Debugged DataFrame creation and manipulation code, focusing on merging DataFrames using nested loops and adjusting legend positions in plots.

Achievements

  • Successfully implemented a robust data processing function that handles timezone-aware datetime objects.
  • Enhanced data visualization capabilities with informative histograms and improved legend positioning.
  • Improved performance of DataFrame operations through optimization techniques.

Pending Tasks

  • Further testing of the optimized DataFrame operations in different scenarios to ensure robustness and efficiency.
