all you need to provide is a list of rows indexes or labels as a param to this method. By defaultdrop()methodremoves the rowsand returns a copy of the updated DataFrame instead of replacing the existing referring DataFrame. If you want to remove from the DataFrame in place usein...
1.使用.drop()方法删除列:创建一个DataFrame,使用.drop()方法删除指定的列,并观察返回值和原始数据。 2.使用.drop()方法的inplace参数:在上述DataFrame中,使用.drop()方法的inplace=True参数删除另一列,并观察原始数据的变化。 3.使用赋值操作删除列:在DataFrame中将一列赋值为np.nan,然后使用.dropna()方法删除...
inplace=False,默认该删除操作不改变原数据,而是返回一个执行删除操作后的新dataframe; inplace=True,则会直接在原数据上进行删除操作,删除后就回不来了。 例子: >>>df = pd.DataFrame(np.arange(12).reshape(3,4), columns=['A', 'B', 'C', 'D']) ...
