Returns ------- `pandas.api.typing.Expression` A deferred object representing a column of a DataFrame. See Also -------- DataFrame.query : Query columns of a dataframe using string expressions. Examples -------- You can use `col` in `assign`. >>> df = pd.DataFrame({"name": ["beluga", "narwhal"], "speed": [100, 110]}) >>> df.assign(name_titlecase=pd.col("name").str.title()) name speed name_titlecase 0 beluga 100 Beluga 1 narwhal 110 Narwhal You can also use it for filtering. >>> df.loc[pd.col("speed") > 105] name speed 1 narwhal 110 zExpected Hashable, got: c|jvrOt|jj}d}t||kDr|d|dz}dd|d}t ||S)NZz...]zColumn 'z;' not found in given DataFrame.
