🐍 Python List Comprehension Exercises

Practice exercises demonstrating Python list comprehensions for data transformation, column renaming, and conditional filtering using the Seaborn car_crashes dataset.

Concepts Covered

• List comprehensions with conditional logic
• String manipulation (uppercase, prefix addition)
• Column name transformation patterns
• Boolean flag creation for filtering

Exercises

1. Uppercase + Prefix — Rename numeric columns to uppercase with "NUM_" prefix
2. String Matching — Flag columns that don't contain "no" in their name
3. Filtered DataFrame — Create a subset using the flag rules above
