Because in the previous automation work, almost every script has to be run at the time node , Like the first day of the week , The first and last day of each month, etc . This involves the calculation of time , But there is no ready-made package , You can only write one by yourself (╯‵□′)╯︵┻━┻.
This script contains the time nodes used by general automated reports .
day = Sometime(timestr="2019-04-25") # Specify the base date
print(day.today)
print(day.yesterday)
print(day.month(n_mon=2)) # 2 A few months later
print(day.month_start(n_mon=5)) # 5 Months later, the first day of the month
print(day.month_end(n_mon=-6)) # 6 The first day of the month months ago
print(day.last_week_start())
print(day.last_week_end())
print(day.today_s)

By two designations “ today ” The way , You can calculate the relevant date based on any day . Very convenient .
If you have any problems during the use , You can contact me .
