用pandas做数据透视表

import pandas as pd
import numpy as np
e_file = pd.ExcelFile(r\'C:/Users/13375/Desktop/python/成绩表.xlsx\')
data = e_file.parse(\'2020年成绩单\')
# print(data)

# print(\'--\'*20)

# pt1 = pd.pivot_table(data, index=[\'age\'],columns=[\'math\'],values=[\'score\'],aggfunc=np.sum,margins=True)
# pd.set_option(\'display.max_columns\',None)  #显示所有的列
# print(pt1)

# ------------------------
pt2 = pd.pivot_table(data, index=[\'age\'],columns=[\'math\'],values=[\'score\'],aggfunc=np.size,margins=True)
print(pt2)
