如何将字符串转换为日期/时间？

Question

I have researched how to do this, but when I print the date and time separately there are other values that appear eg 00:00:00 and 1900-01-01 .

Code:

import datetime
date = datetime.datetime.strptime('17/12/2018', '%d/%m/%Y')
time = datetime.datetime.strptime('13:26:09', '%H:%M:%S')
print(date)
print(time)

Expected Output:

17/12/2018
13:26:09
>>>

Output:

2018-12-17 00:00:00
1900-01-01 13:26:09
>>>

You can simply use the datetime.date() and datetime.time() functions:

import datetime
date = datetime.datetime.strptime('17/12/2018', '%d/%m/%Y')  # this is a datetime
time = datetime.datetime.strptime('13:26:09', '%H:%M:%S')    # this is also a datetime
print(date.date()) # just the date
print(time.time()) # just the time

Output:

2018-12-17   # do date.strftime('%%d/%m/%Y') to create the string representation you want
13:26:09     # default visualisation is same as you want

You create 2 datetime instances - one only by specifying the time, the other buy only specifying the date. The other param is supplied by default.

Alternativly you can use:

date = datetime.datetime.strptime('17/12/2018', '%d/%m/%Y').date()  # date object
time = datetime.datetime.strptime('13:26:09', '%H:%M:%S').time()    # time object
