将 UNIX 时间戳转换为格式为 YYYY-MM-DD 的日期字符串

Question

I'm trying to print whether it's going to rain or not for given date (mostly next day) in terminal. For that I already get OpenWeatherMap from rapidapi.com.

I convert my response to json

response = requests.request("GET", url, headers=headers, params=querystring)
obj = response.text
x = json.loads(obj)
print(x['list'][0])
#part of output
{'dt': 1606676400, 'sunrise': 1606662312, 'sunset': 1606697500,

and i think the dt is some kind of time, i want to convert it to date in format YYYY-MM-DD, but don't know how.

Thanks for all help, and have a nice day!

Answer 1

The format is a UNIX timestamp , by the way a very good way of sharing dates, because no extensive parsing is required and datetime library offers an easy way of parsing it

from datetime import datetime

timestamp = 1606662312
dt_object = datetime.fromtimestamp(timestamp)

[1] 29.11.2020 16:05

EDIT: If you then need the date in a particular string format you can use:

date_string = dt_object.strftime("%Y-%m-%d")
[2] '2020-11-29'

For the interested reader:

UNIX timestamp

It's pretty common to store date and time as a timestamp in a database. 
A Unix timestamp is the number of seconds between a particular date and 
January 1, 1970 at UTC.

Answer 2

Given the output of YYYY-MM-DD in the question, here is an alternative (without the time) -

from datetime import date
dt = 1606676400
dt_convert = date.fromtimestamp(dt)

Run from the interpreter -

>>> dt_convert
datetime.date(2020, 11, 29)
>>> str(dt_convert)
'2020-11-29'
