python 中date datetime time 与str的互转

　　以下全部引入

　　form datetime import datetime， timedelta

　　import time

一、time 转str

　　

二、datetime 转 str

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

三、str 转 datetime

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

四、实例应用

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")
