3、crosstab方法(交叉表):默认计算分组结果的出现次数,如果需要计算其他分组信息(如分组内的均值、方差等),需要制定具体的values和aggfunc,aggfunc作用于values制定的属性上 pandas.crosstab(index,columns,values=None,rownames=None,colnames=None,aggfunc=None, margins=False,margins_name='All',dropna=True,normalize=...
Syntax: DataFrame.pivot_table(self, values=None, index=None, columns=None, aggfunc='mean', fill_value=None, margins=False, dropna=True, margins_name='All', observed=False) Parameters: Returns:DataFrame Example: Download the Pandas DataFrame Notebooks fromhere. Previous:DataFrame - pivot() funct...
