Get year,month and day from python variable

Question

I'd like to get the break of a variable by year, month and day. Here's what I got:

import datetime
from datetime import date, timedelta
yesterday = date.today() - timedelta(1)
print (yesterday)
year = datetime.date.yesterday.year
month = datetime.date.yesterday.month
day=datetime.date.yesterday.day
print (year)
print (month)
print (day)

I'm getting an error that datetime.date has no attribute. I'm a total noob at python and I'm stuck, any help is appreciated

Solution 1

you were close

import datetime
from datetime import date, timedelta
yesterday = date.today() - timedelta(1)
print (yesterday)
year = yesterday.year
month = yesterday.month
day=yesterday.day
print (year)
print (month)
print (day)

result is

2019-03-10

2019

10

Solution 2

You can also simplify your import statements like so:

from datetime import datetime, timedelta

yesterday = datetime.today() - timedelta(1)

print(yesterday)

year = yesterday.year
month = yesterday.month
day = yesterday.day

print(year)
print(month)
print(day)

You will get the output:

2019-03-10 21:19:36.695577
2019
3
10

Solution 3

You can use strftime method

A simple example:

>>> from datetime import datetime
>>> now = datetime.utcnow()
>>> year_month_day_format = '%Y-%m-%d'
>>> now.strftime(year_month_day_format)
'2020-11-06'
>>> hour_minute_format = '%H:%M'
>>> now.strftime(hour_minute_format)
'22:54'

Hopping, it will help someones

just a note, I know I don't need the 'print (yesterday)' line, it was just testing for me

this works, Baris just beat you, thanks for the simplifying tip

That's how it is ;)... I will point out however that yesterday will also contain the time as shown in the output I added. From there, you can also access other attributes such as yesterday.hour, yesterday.microsecond, yesterday.minute, yesterday.second or even split individual fractions of time with yesterday.time() and get the digit that corresponds to the day of the week with yesterday.weekday().

you could also strip the time information using -- yesterday.strftime('%d-%m-%Y')
