日期格式不正确，有时间

Question

now = datetime.datetime.now()
today = str(now.year) + '-' + str(now.month) + '-' + str(now.day)
date = datetime.datetime.strptime(today, "%Y-%m-%d")
print(date) # 2020-11-13 00:00:00

Why is time added to date? I explicitly define my format without time. How to have date only: 2020-11-13?

Answer 1

In your code, date is a datetime object (not a date object), it has attributes hour, minute and second set to zero. if you print it, you effectively call its __str__ method - which returns isoformat with space as separator. That's why you get Ymd H:M:S .

If you want today's date as string, simply use

from datetime import date
print(date.today())
# or
print(date.today().strftime("%Y-%m-%d")) # same as date.today().isoformat()
# or even
from datetime import datetime
print(datetime.today().strftime("%Y-%m-%d"))

# all print to 
# 2020-11-13

Answer 2

The format string you specify in datetime.datetime.strptime() is the format of the string argument you pass to the method, not the output. The return value of the method is datetime.datetime object. Anyway, you can use datetime.date.today() to get datetime.date , ie without time.
