DataFrame.dropna()

axis : {0 or ?index?, 1 or ?columns?}, 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

inplace : boolean, default False

If True, do operation inplace and return None.
