datetime – Getting todays date in YYYY-MM-DD in Python?

You can use strftime:

>>> from datetime import datetime
>>> datetime.today().strftime(%Y-%m-%d)
2021-01-26

Additionally, for anyone also looking for a zero-padded Hour, Minute, and Second at the end: (Comment by Gabriel Staples)

>>> datetime.today().strftime(%Y-%m-%d-%H:%M:%S)
2021-01-26-16:50:03

You can use datetime.date.today() and convert the resulting datetime.date object to a string:

from datetime import date
today = str(date.today())
print(today)   # 2017-12-26

I always use the isoformat() method for this.

from datetime import date    
today = date.today().isoformat()
print(today)  # 2018-12-05

Note that this also works on datetime objects if you need the time in the standard ISO 8601 format as well.

from datetime import datetime
now = datetime.today().isoformat()
print(now)  # 2018-12-05T11:15:55.126382
