python 建立 XLS文件,自动生辰日期、星期。



import xlrd
from datetime import datetime, timedelta

# 打开Excel文件
workbook = xlrd.open_workbook('attendance1.xls')

# 获取第一个工作表
sheet = workbook.sheet_by_index(0)

# 读取D列的数据,从第二行开始
dates = sheet.col_values(3, start_rowx=1)

# 获取当前日期
current_date = datetime.now()

# 生成5月1日的日期
target_date = datetime(current_date.year, 5, 1)

# 循环补充缺少的星期数
while current_date < target_date:
    # 根据当前日期判断是否存在于D列数据中
    if current_date.date() not in dates:
        # 获取当前日期的星期
        weekday = current_date.strftime('%A')
        # 在D列末尾添加新的日期和星期
        dates.append(current_date.date())
        sheet.write(len(dates), 3, current_date.date())
        sheet.write(len(dates), 4, weekday)
    # 增加一天
    current_date += timedelta(days=1)

# 保存修改后的Excel文件
workbook.save('attendance1.xls')
