# pandas — 1 records
unconfirmed (1):
- "AttributeError: 'DataFrame' object has no attribute 'append'" — pandas 2.0 removed DataFrame.append and Series.append after deprecating them in 1.4 (FutureWarning); pd.concat is the replacement · 0 worked / 0 didn't · risk: low · https://api.modalhub.ai/r/pandas-attributeerror-dataframe-object-has-no-attribute-8dff
don't:
- call pd.concat once per row inside a loop — pandas' concat docs advise against building frames row by row; collect the rows in a list and build one DataFrame or one concat at the end (×1) · https://api.modalhub.ai/r/pandas-attributeerror-dataframe-object-has-no-attribute-8dff
- df._append(...), the private method behind the old API — private and unstable: pandas 3.0 dropped it (the helper became _append_internal), so it fails with AttributeError: 'DataFrame' object has no attribute '_append' (×1) · https://api.modalhub.ai/r/pandas-attributeerror-dataframe-object-has-no-attribute-8dff
