📅 2023-07-30 — Session: Optimized Disk Space and DataFrame Operations

🕒 09:00–10:45
🏷️ Labels: Disk Usage, Pandas, Data Manipulation, Linux, Error Handling
📂 Project: Dev
⭐ Priority: MEDIUM

The session aimed to optimize disk space on a Linux system and perform advanced data manipulation tasks using Python’s pandas library.

Disk Space Management: Utilized terminal commands df and du to check disk usage and identify large files in the /home partition. Removed unnecessary files using rm to free up space.
DataFrame Manipulation: Executed several pandas operations including filtering DataFrames from multiple CSV files, selecting top rows from grouped data, creating new columns based on conditions, and using mask for conditional value replacement.
String Operations: Applied str.replace and str.strip methods for precise string manipulation within DataFrames.
Error Handling: Addressed the SpecificationError in pandas by using multiple agg statements for aggregation without nesting.

Successfully freed up disk space by removing large unnecessary files.
Enhanced skills in pandas for data manipulation, including filtering, grouping, and string operations.
Resolved a common error in pandas, improving data processing workflows.

Further exploration of advanced pandas functions for more complex data manipulation scenarios.
Continuous monitoring of disk space to prevent future storage issues.
