獲取GMT時間兩小時前的Python 2.7

Question

嗨，我遇到麻煩時兩小時前在一個類似的功能我get_timestamp =>

def get_timestamp(): 
    """Return correctly formatted timestamp""" 
    return strftime("%Y-%m-%dT%H:%M:%SZ", gmtime()) 
def two_hours_ago(): 
    """Return correctly formatted timestamp""" 
    last = (date.today() - timedelta(hours=1)) 
    return strftime("%Y-%m-%dT%H:%M:%SZ", gmtime()-'2HOURS') 

我嘗試這樣做：

def two_hours_ago(): 
    """Return correctly formatted timestamp""" 
    today = date.today() 
    yesterday = (today - timedelta(hours=2)) 
    print(yesterday.timetuple()) 
    return strftime("%Y-%m-%dT%H:%M:%SZ", yesterday.timetuple()) 

UPDATE 謝謝 黃燕浩

我正在尋找亞馬遜MWS的ISO格式返回2小時的間隔，我用下面的函數返回格式正確的時間。

def two_hours_ago(): 
    """Return correctly formatted timestamp""" 
    now = datetime.now() 
    two_hours_ago = (now - timedelta(hours=2)) 
    return two_hours_ago.strftime("%Y-%m-%dT%H:%M:%SZ") 
def now(): 
    """Return correctly formatted timestamp""" 
    now = datetime.now() 
    two_hours_ago = (now - timedelta(hours=0)) 
    return two_hours_ago.strftime("%Y-%m-%dT%H:%M:%SZ") 

Answer 1

我真的不明白代碼是today = date.today()。

是的，例如，2017/10/18 00:00:00？

以下代碼可能在兩個小時前獲得時間。我不知道你是什麼或不..

from datetime import datetime, timedelta 

def two_hours_ago(): 
    """Return correctly formatted timestamp""" 
    now = datetime.now() 
    two_hours_ago = (now - timedelta(hours=2)) 
    return two_hours_ago.strftime("%Y-%m-%dT%H:%M:%SZ") 

對於這個代碼，它將執行諸如以下

>>> two_hours_ago() 
'2017-10-19T11:28:40Z'
