Convert 12 hour time string into datetime or time

Question

Ive been trying to use time.strptime(string1,\'%H:%M\'), with no success

How can I get the following:

Input     Output
3:14AM  -> 03:         


        

Answer 1

You're missing %p (Locale’s equivalent of either AM or PM).

time.strptime(string1,'%H:%M%p')

Answer 2

Use %I for 12 hour times and %p for the am or pm as follows:

from datetime import datetime
 
for t in ["3:14AM", "9:33PM", "12:21AM", "12:15PM"]:
    print(datetime.strptime(t, '%I:%M%p').strftime("%H:%M"))

Giving you the following output:

03:14
21:33
00:21
12:15 
    

The formats used are documented in strftime() and strptime() Behavior

Answer 3

The problem requires that you first strptime using %I for the 12 hour time and adding the directive %p for AM or PM to get a time object; altogther '%I:%M%p'. Then use strftime to format the time object into a string:

Trials:

>>> tm = time.strptime('12:33AM', '%I:%M%p')
>>> time.strftime('%H:%M', tm)
'00:33'
>>> tm = time.strptime('9:33PM', '%H:%M%p')
>>> time.strftime('%H:%M', tm)
'09:33'
