python 中date datetime time 與str的互轉

　　如下所有引入

　　form datetime import datetime， timedelta

　　import time

1、time 轉str

　　

 

 

2、datetime 轉 str

　　str_date = datetime.now().strftime("%Y-%m-%d")   -------(%04d%02d%02d)此種格式化注意

 

3、str 轉 datetime

　　start_date = datetime.strptime("2016-06-07", "%Y-%m-%d")  

4、實例應用

def datelist(start, end):
    start_date = datetime.strptime(start, "%Y-%m-%d")
    end_date = datetime.strptime(end, "%Y-%m-%d")
    result = []
    curr_date = start_date
    while curr_date != end_date:
        # result.append("%04d-%02d-%02d" % (curr_date.year, curr_date.month, curr_date.day))
        result.append(curr_date.strftime("%Y-%m-%d"))
        curr_date += timedelta(1)
    # result.append("%04d-%02d-%02d" % (curr_date.year, curr_date.month, curr_date.day))
    result.append(curr_date.strftime("%Y-%m-%d"))
    return result

if __name__ == "__main__":
    print datelist("2016-06-07", "2016-06-27")
