Python 通过 xlwings 读取 Excel 数据

程序比较简单，直接上程序。

# -*- coding: utf-8 -*-

# 统计时间, 只有时间要改

START_ROW = 2 # 处理Excel文件开始行
END_ROW = 200 # 处理Excel结束行

# 天数 * 每天工作时间 * 分钟
WORK_TIME = 30 * 22 * 60

# 关键设备清单
key_machine = ['609', '610', '621', '622', '623', '624',

app = xw.App(visible=True, add_book=False)
wb_source = app.books.open('downTimeData.xls') # 打开Excel文件 downTimeData.xls
sheet = wb_source.sheets[0]  # 选择第0个表单

# 需每月修改时间
start_datetime = datetime.strptime(START_TIME, '%Y-%m-%d %H:%M:%S') # 把开始统计时间转换为DateTime
end_datetime = datetime.strptime(END_TIME, '%Y-%m-%d %H:%M:%S') # 把结束统计时间转换为DateTime
