python各种类型日期转换大全

最近写python做各种日期转换比较多，顺便总结一下，先上张图：

 # 根据字符串类型转日期 返回值类型<class 'time.struct_time'>

 st_time = time.strptime('2019-4-30 11:32:23', '%Y-%m-%d %H:%M:%S')

 print(str(st_time) + " 类型：" + str(type(st_time)))

 # time.struct_time(tm_year=2019, tm_mon=4, tm_mday=30, tm_hour=11, tm_min=32, tm_sec=23, tm_wday=1, tm_yday=120, tm_isdst=-1) 类型：<class 'time.struct_time'>

 # 根据<class 'time.struct_time'>日期类型转字符 返回值类型<class 'str'>

 str_time = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())

 print(str_time + " 类型：" + str(type(str_time)))

 # 2019-04-26 12:33:04 类型：<class 'str'>

 # 获取当前日期 返回值类型<class 'time.struct_time'>

 st_time = time.localtime()

 print(str(st_time) + " 类型：" + str(type(st_time)))

 # 获取当前日期时间戳 返回值类型<class 'float'>

 float_time = time.time()

 print(str(float_time) + " 类型：" + str(type(float_time)))

 # 根据<class 'time.struct_time'>日期类型转换为时间戳 返回值类型<class 'float'>

 # 1556256409.0 类型：<class 'float'>

 # 根据<class 'float'>日期戳转换为struct_time日期 返回值类型<class 'time.struct_time'>

 st_time = time.localtime(time.time())
