                date_resc = input('enter the date you want to reschedule : ')
                date_for_resc = datetime.datetime.strptime(date_resc, '%Y-%m-%d %H:%M:%s')
                print('the appointment is rescheduled for ',name_resch,'and on',date_for_resc)
                resch_pat.append(name_resch)

CodePudding user response：

In this line, you enter the date with seconds:

enter the date you want to get appointed (yyyy-mm-dd hh:mm): 2023-10-9 8:31:31

But the conversion is not correct with this pattern, you have here (c:\Desktop\vsc\JavaScript\05-Guess-My-Number\starter\doctor.py):

date = datetime.datetime.strptime(appnt_date,'%Y-%m-%d %H:%M')

The conversion should be:

date = datetime.datetime.strptime(appnt_date,'%Y-%m-%d %H:%M:%s')
