将日期转换为特定格式时出错

Question

I have the following format for my dates 1952-02-04 00:00:00

I need the format to be month/day/year

How do I go about this currently I have

if clientDob is not None:
            clientDob = datetime.datetime.strptime(clientDob, '%Y-%m-%d').strftime('%m/%d/%y')

the error I get is

time data 'Birth Dt' does not match format '%Y-%m-%d'

Answer 1

Use

clientDob = datetime.datetime.strptime(clientDob, '%Y-%m-%d %H:%M:%S').strftime('%m/%d/%y')

for datetime parsing your string must match the source string exactly . It contains time-information, you need to match it.

import datetime 
clientDob = "2018-12-21 12:13:14"

clientDob = datetime.datetime.strptime(clientDob, '%Y-%m-%d %H:%M:%S').strftime('%m/%d/%y')
print(clientDob)

Output:

12/21/18
