    Walkthrough

    The changes involve simplifying the validate_empty_cells method in the SDRFSchema class by removing Python version-specific conditional logic. The method now uses the map method unconditionally across all Python versions, eliminating the previous differentiation between Python 3.8 and above versions for DataFrame validation.

    Changes

    File Change Summary
    sdrf_pipelines/sdrf/sdrf_schema.py Removed version-specific conditional logic in validate_empty_cells method, now using map method universally

    Poem

    🐰 A Rabbit's Ode to Code Simplification 🥕

    Version checks, once a tricky dance,
    Now streamlined with a single glance
    Map method reigns, no version fear
    Cleaner code, the path is clear!
    Hop, hop, simplicity is near!

      • @coderabbitai modularize this function.
    • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
      • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
      • @coderabbitai read src/utils.ts and generate unit testing code.

    The PR leaves commented out code that should be removed since it's no longer needed after the migration to using map() only.

    ✅ Remove commented-out code to improve code clarity and maintainability
    Suggestion Impact:The commit removed the commented-out code blocks that were checking Python version to decide between map and applymap usage

    code diff:

    -        # if sys.version_info <= (3, 8):
    -        #     # Use map for Python versions less than 3.8
             validation_results = panda_sdrf.map(validate_string)
    -        # else:
    -        #     # Use applymap for Python versions 3.8 and above
    -        #     validation_results = panda_sdrf.applymap(validate_string)

    Remove the commented-out code since it's no longer needed and can cause confusion.
    The code now correctly uses map which is the recommended approach in pandas 2.1+.

    sdrf_pipelines/sdrf/sdrf_schema.py [364-369]

    -# if sys.version_info <= (3, 8):
    -#     # Use map for Python versions less than 3.8
     validation_results = panda_sdrf.map(validate_string)
    -# else:
    -#     # Use applymap for Python versions 3.8 and above
    -#     validation_results = panda_sdrf.applymap(validate_string)
    • Apply this suggestion
    Suggestion importance[1-10]: 7

    Why: The suggestion correctly identifies redundant commented-out code that should be removed since the PR has already made the decision to use map() consistently. Removing dead code improves readability and prevents confusion about which code path is actually being used.

    364-369: LGTM! Consider removing the commented code.

    The change to use map unconditionally is correct as it aligns with pandas' deprecation of applymap since version 2.1.0. However, since the version-specific code is no longer needed, consider removing the commented code for cleaner maintenance.

    -        # if sys.version_info <= (3, 8):
    -        #     # Use map for Python versions less than 3.8
    -        #     validation_results = panda_sdrf.map(validate_string)
    -        # else:
    -        #     # Use applymap for Python versions 3.8 and above
    -        #     validation_results = panda_sdrf.applymap(validate_string)
    +        validation_results = panda_sdrf.map(validate_string)
