【Python辦公自動化筆記-Excel篇9】跨工作表求和

# 跨工作表求和
from openpyxl import load_workbook

path = 'D:/sample.xlsx'
wb = load_workbook(path)

data = []
for ws in wb.worksheets:         # 拜訪每張工作表
    data.append(ws['E5'].value)  # 將E5的值加入data列表
print(sum(data))                 # 印出data列表中各元素的和
# 改用較淺白一點的寫法：
ans = 0
for ws in wb.worksheets:
    ans += ws['E5'].value
print(ans)

ans = sum([ws['E5'].value for ws in wb.worksheets])
print(ans)
