Type: instancemethod String form: <bound method DataFrame.dropna of Qu1 Qu2 Qu3 0 1 2 1 1 3 3 5 2 4 1 2 3 3 2 4 4 4 3 4> File: /Library/Python/2.7/site-packages/pandas-0.12.0_307_g3a2fe0b-py2.7-macosx-10.8-intel.egg/pandas/core/frame.py Definition: data.dropna(self, axis=0, how='any', thresh=None, subset=None) Docstring: Return object with labels on given axis omitted where alternately any or all of the data are missing Parameters ---------- axis : {0, 1}, or tuple/list thereof Pass tuple or list to drop on multiple axes how : {'any', 'all'} any : if any NA values are present, drop that label all : if all values are NA, drop that label thresh : int, default None int value : require that many non-NA values subset : array-like Labels along other axis to consider, e.g. if you are dropping rows these would be a list of columns to include Returns ------- dropped : DataFrame
inplace : boolean, default False If True, fill the DataFrame in place. Note: this will modify any other views on this DataFrame, like if you took a no-copy slice of an existing DataFrame, for example a column in a DataFrame. Returns a reference to the filled object, which is self if inplace=True
