Python 3: Formatting a DateTime Object as a String

In Python 3, you can use the strftime method to format a datetime object as a string.
Example:
from datetime import datetime, date, time
dt = datetime(2021, 11, 28, 16, 12, 54)
s1 = dt.strftime('%Y/%m/%d %H:%M:%S')
s2 = dt.strftime('%Y-%M%-%D %H:%M')
s3 = dt.strftime('%F')
s4 = dt.strftime('%D')
s1, s2, s3, s4
Output:
(
'2021/11/28 16:12:54',
'2021-12%D 16:12',
'2021-11-28',
'11/28/21'
)
Here are all datetime format specifications:
- %Y: Four-digit year (e.g., 2021)
- %y: Two-digit year (e.g., 21)
- %m: Two-digit month (01, 02, …)
- %d: Two-digit day (01, 02, 03,…)
- %H: Hour (24-hour clock)
- %I: Hour (12-hour clock)
- %M: Minute (01, 02, …, 59)
- %S: Second
- %w: Weekday as integer
- %U: Week number of the year (Sunday is the first day of the week)
- %W: Week number of the year (Monday is the first day of the week)
- %z: UTC time zone offset as +HHMM or -HHMM
- %D: Shortcut for %m/%d/%y (e.g., 11/05/21)
- %F: Shortcut for %Y-%m-%d (e.g., 2021-11-05)
