python - 在 Python 中读取 Excel 文件透视

Question

我想从 Excel 文件中检索数据。

以下是数据:

这是我想要的结果:

这是我开始编写的代码:

from openpyxl import load_workbook
wb = load_workbook('C:\\Fichiers_Excel\\Team.xlsx')
m = wb.active
# Retrieve the value of a certain cell
team_1_captain=m['A2'].value,m['B2'].value,m['D2'].value,m['E2'].value
team_1_player=m['A6'].value,m['B6'].value,m['D6'].value,m['E6'].value
team_1= m['A2'].value,m['B2'].value,m['D2'].value,m['E2'].value,m['B6'].value,m['D6'].value,m['E6'].value
print (team_1)

Answer 1

使用pandas ，您可以操作数据，将团队作为行，将 captain 和 player 作为列，然后加入日期值:

import pandas as pd

df = pd.read_excel("<path to your file>.xlsx")

teams = df.set_index(["Team", "Status"])["Name"].unstack()

cols = ["Monday", "Tuesday"]
days = []
for i in ["player", "captain"]:
    days.append(df[df["Status"] == i].groupby("Team")[cols].first().rename(columns={col: "{}_{}".format(i, col) for col in cols}))

days = pd.concat(days, axis=1)

result = teams.join(days)
result[["captain", "captain_Monday", "captain_Tuesday", "player", "player_Monday", "player_Tuesday"]]
