Enhanced Data Processing and Visualization in Python

📅 2023-03-27 — Session: Enhanced Data Processing and Visualization in Python

🕒 22:30–23:55
🏷️ Labels: Python, Data Processing, Pandas, Matplotlib, Timezone Handling
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The goal of this session was to enhance data processing and visualization techniques using Python, focusing on handling date ranges, visualizing data with histograms, and addressing timezone-related issues in Pandas.

Key Activities:

• Developed a Python function to process CSV and Excel files by filtering data based on specified date ranges.
• Implemented histogram plotting for date columns in DataFrames using Matplotlib, including enhancements for clarity with titles and labels.
• Addressed timezone-related errors in Pandas, ensuring proper handling of datetime objects and resolving comparison errors using tz_localize() and tz_convert() methods.
• Resolved time zone discrepancies in DataFrame merges to ensure accurate datetime operations.
• Optimized DataFrame operations by replacing iterrows with apply and concat methods for improved performance.

Achievements:

• Successfully created and tested functions for data processing and visualization.
• Enhanced error handling for timezone-aware datetime operations in Pandas.
• Improved performance of DataFrame operations by adopting more efficient methods.

Pending Tasks:

• Further testing and validation of the optimized DataFrame operations in different scenarios.
• Exploration of additional visualization techniques to enhance data insights.
