print(datedf.head(10))
print(datedf.tail(10))datedf.to_excel('/Users/kangyongqing/Downloads/'+'日历'+str(datetime.date.today())+'.xlsx',index=False)查看并保存日历到本地：
import calendar
cal=calendar.calendar(2024,2,1,6,4)
print(cal)
print(type(cal))with open('/Users/kangyongqing/Downloads/未命名.txt','w',encoding='utf-8') as file:file.write(cal)
2,1,6,4为控制展示格式间距，可以适当调整。
使用with语句是一个好习惯，因为它会在执行完代码块后自动关闭文件。
