How to modify datetime.datetime.hour in Python?
Question:
I want to calculate the seconds between now and tomorrow 12:00. So I need to get tomorrow 12:00 datetime object.
This is pseudo code:
today_time = datetime.datetime.now()
tomorrow = today_time + datetime.timedelta(days = 1)
tomorrow.hour = 12
result = (tomorrow-today_time).total_seconds()
But it will raise this error:
AttributeError: attribute 'hour' of 'datetime.datetime' objects is not writable
How can I modify the hour or how can I get a tomorrow 12:00 datetime object?
Answers:
Try this:
tomorrow = datetime.datetime(tomorrow.year, tomorrow.month, tomorrow.day, 12, 0, 0)
Use the replace method to generate a new datetime object based on your existing one:
tomorrow = tomorrow.replace(hour=12)
Return a datetime with the same attributes, except for those attributes given new values by whichever keyword arguments are specified. Note that tzinfo=None can be specified to create a naive datetime from an aware datetime with no conversion of date and time data.
