Python - 類型錯誤：需要一個 integer（獲取類型 datetime.datetime）

Question

我有以下代碼：

import datetime
from datetime import datetime as dt

def ceil_dt(dt, delta):
    return dt + (dt.min - dt) % delta

NextInterval5m = ceil_dt(now, timedelta(minutes=5))

unixtime5m = dt.fromtimestamp(NextInterval5m)

問題是我不斷收到以下錯誤：

TypeError: an integer is required (got type datetime.datetime)

有人可以幫我解決這個問題嗎？ 我不明白我應該轉換NextInterval5m以使其工作。 我正在嘗試將NextInterval5m轉換為 Unix 時間戳

Answer 1

您應該能夠通過在datetime.datetime object 上使用.timestamp()將其轉換為 unix 時間戳。 However, this function is exclusive to Python 3. If you need something for python 2, you can use .total_seconds() which requires a datetime.time_delta object instead.

文檔： https://docs.python.org/3.8/library/datetime.html#datetime.datetime.timestamp

Answer 2

如果您使用的是 python 3.3+，請使用.timestamp()

import datetime
from datetime import datetime as dt
from datetime import timedelta

def ceil_dt(dt, delta):
    return dt + (dt.min - dt) % delta

now = dt.now()
NextInterval5m = ceil_dt(now, timedelta(minutes=5))
unixtime5m = NextInterval5m.timestamp()
print(unixtime5m)

Output：

1596926400.0

或者

import datetime
from datetime import datetime as dt
from datetime import timedelta

def ceil_dt(dt, delta):
    return dt + (dt.min - dt) % delta

now = dt.now()
NextInterval5m = ceil_dt(now, timedelta(minutes=5))
unixtime5m = NextInterval5m.timestamp()

print((NextInterval5m - datetime.datetime(1970,1,1)).total_seconds())
