Python time strptime() function The strptime() function in Python is used to format and return a string representation of date and time. It takes in the date, time, or both as an input, and parses it according to the directives given to it.
Use datetime. strftime(format) to convert a datetime object into a string as per the corresponding format . The format codes are standard directives for mentioning in which format you want to represent datetime. For example, the %d-%m-%Y %H:%M:%S codes convert date to dd-mm-yyyy hh:mm:ss format.
Use the datetime. date() Function to Convert Datetime to Date in Python. The datetime() constructor can be utilized to generate a date. The datetime() constructor has three parameters: day, month, and year.
Use datetime.replace:
from datetime import datetime
dt = datetime.strptime('26 Sep 2012', '%d %b %Y')
newdatetime = dt.replace(hour=11, minute=59)
Also worth noting: datetime.replace returns a new copy of the datetime (since datetime is immutable): it is like str.replace in that regard.
datetime.replace() will provide the best options. Also, it provides facility for replacing day, year, and month.
Suppose we have a datetime object and date is represented as:
"2017-05-04"
>>> from datetime import datetime
>>> date = datetime.strptime('2017-05-04',"%Y-%m-%d")
>>> print(date)
2017-05-04 00:00:00
>>> date = date.replace(minute=59, hour=23, second=59, year=2018, month=6, day=1)
>>> print(date)
2018-06-01 23:59:59
If you have a date as a datetime.datetime (or a datetime.date) instance and want to combine it via a time from a datetime.time instance, then you can use the classmethod datetime.datetime.combine:
import datetime
dt = datetime.datetime(2020, 7, 1)
t = datetime.time(12, 34)
combined = datetime.datetime.combine(dt.date(), t)
