277-351: Consider refactoring to reduce complexityWhile the quote consistency changes are good, this method has high complexity as noted by static analysis (21 local variables, 13 branches). Consider breaking this into smaller helper methods.
For example, you could extract header processing and row processing into separate methods:
+ def _extract_table_headers(self, table: Tag) -> list: + """Extract headers from table with colspan handling.""" + headers = [] + thead_rows = table.select("thead tr") + if thead_rows: + header_cells = thead_rows[0].select("th") + for cell in header_cells: + text = cell.get_text().strip() + colspan = int(cell.get("colspan", 1)) + headers.extend([text] * colspan) + else: + first_row = table.select("tr:first-child") + if first_row: + for cell in first_row[0].select("th, td"): + text = cell.get_text().strip() + colspan = int(cell.get("colspan", 1)) + headers.extend([text] * colspan) + return headers + + def _extract_table_rows(self, table: Tag, headers: list) -> list: + """Extract rows from table with colspan handling.""" + # Implementation here...

52-52: LGTM: Quote consistency improvementGood practice to standardize on double quotes for string literals.
160-160: LGTM: Trailing comma additionAdding the trailing comma improves maintainability and reduces diff noise when adding new items to the list.
213-276: LGTM: CSS selector quote consistencyThe standardization to double quotes in CSS selectors and string literals improves code consistency. The logic for table data detection remains unchanged and correct.
793-814: Excellent bug fix for type safetyThis change properly addresses the TypeError when
keep_attrsorkeep_data_attributesare passed as boolean values instead of lists. The implementation correctly handles all edge cases:
False→ empty list[]Trueor other truthy single values → wrapped in list[value]- Already lists → unchanged
Noneor other falsy values → empty list[]This ensures safe concatenation with
IMPORTANT_ATTRS + keep_attrs.
899-901: LGTM: Error message formatting improvementThe multi-line formatting improves readability of the error message.
950-952: LGTM: Consistent error logging formatThe improved formatting for error logging maintains consistency with the project's logging patterns.
998-998: LGTM: Quote consistency in table exclusion checkConsistent with the overall double-quote standardization throughout the file.
1428-1428: LGTM: Mathematical calculation formattingThe spacing around the exponentiation operator improves readability.
1439-1443: LGTM: Multi-line formatting for complex expressionsBreaking the complex sum expression across multiple lines significantly improves readability.
1582-1592: LGTM: Improved error logging formattingThe multi-line formatting for error messages improves code readability and maintainability.
1712-1712: LGTM: Dictionary formatting consistencySingle-line dictionary formatting is appropriate for simple structures and maintains consistency.
Summary
Fixes
#1226: This PR resolves aTypeErrorthat occurs whenkeep_data_attributes=Falseis passed in theCrawlerRunConfig. The issue was due to a list concatenation with abool, which is now safely handled by convertingFalseto an empty list before concatenation.List of Files Changed and Why
path/to/affected_file.py– Added type-check and logic to ensurekeep_attrsandkeep_data_attributesare always treated as lists, preventing runtime errors during attribute removal.test_keep_attrs_fix.py– Added a test script to verify that the fix works for edge cases likeFalse,True,None, and missing keys.How Has This Been Tested?
