Assigning datetime.datetime output to a variable, rather than to object

My Code:

import datetime as dt
#print(potus[0:])
#Start_date=0
date_format='%m/%d/%y %H:%M'
for row in potus[0:4]:
    appt_start_date=row[2]
    print(appt_start_date)
    Start_date=dt.datetime.strptime(appt_start_date,date_format)
    print(Start_date)
    row[2]=Start_date
    print(row[2])
    
print(potus[0:3])

What I expected to happen:
I was hoping this code updates all the row[2] values in potus list with updated date format.

What actually happened:
when the potus list is updated it at row[2] it shows output as datetime.datetime(2015, 1, 6, 9, 30) instead of 2015-01-06 09:30:00.
When I tried to debug, and added print messages at every line, while the code executes, the variables looks right. However in the end when it updates the potus list, and when I print Potus list, it doesn’t get updated correctly.

Replace this line with the output/error

Hello @sri.medisetti, This will help.

Why didn't the command dt.datetime.strptime result in 1984-12-24 00:00:00 instead of datetime.datetime(1984, 12, 24, 0, 0)?

dt.datetime.strptime() function return datetime object like. datetime.datetime(1984, 12, 24, 0, 0) that is why you have datetime.datetime(2015, 1, 6, 9, 30) in your list data. but when you print datetime object it actually call built-in object.__str__() function which turn it into human readable format. like (1984-12-24 00:00:00) Example: date_1_str = "24/12/1984" date_1_dt = dt.datetime.strptime(date_1_str, "%d/%m/%Y") This is datetime object print(type(date_1_dt)) <class 'datetime.dateti…

Let me know if you still have any doubt.

Yes, that is very helpful…As printing individual object was showing different values than printing the whole list, this confusion arises…
