I want to input the date in flask and can calculate the date(add to 3 days later, or not let system take 2022-02-32 input from user), I searched that we can use the function below but what do I missed to correct?
Here is the function I start with, I thought could help:
from datetime import date
date = datetime.datetime.strptime(date, "%m/%d/%y")
new_date = date + datetime.timedelta(days= diff)python flask input URL (date,diff, operation-add,del) how can I correct
example URL input:
http://127.0.0.1:5000/data?dtae=2022-01-01&diff=5&op=a{add,del}
http://127.0.0.1:5000/data?dtae=2022-01-01&diff=13&op=add
http://127.0.0.1:5000/data?dtae=2022-01-01&diff=5&op=del
optput:
the 13 days later is 2022-01-14 the 5 days back is 2021-12-27
