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：

 1 # 根据字符串类型转日期 返回值类型<class 'time.struct_time'>
 2 st_time = time.strptime('2019-4-30 11:32:23', '%Y-%m-%d %H:%M:%S')
 3 print(str(st_time) + " 类型：" + str(type(st_time)))
 4 # 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'>
 5 
 6 # 根据<class 'time.struct_time'>日期类型转字符 返回值类型<class 'str'>
 7 str_time = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())
 8 print(str_time + " 类型：" + str(type(str_time)))
 9 # 2019-04-26 12:33:04 类型：<class 'str'>
10 
11 # 获取当前日期 返回值类型<class 'time.struct_time'>
12 st_time = time.localtime()
13 print(str(st_time) + " 类型：" + str(type(st_time)))
14 # time.struct_time(tm_year=2019, tm_mon=4, tm_mday=26, tm_hour=12, tm_min=47, tm_sec=41, tm_wday=4, tm_yday=116, tm_isdst=0) 类型：<class 'time.struct_time'>
15 
16 # 获取当前日期时间戳 返回值类型<class 'float'>
17 float_time = time.time()
18 print(str(float_time) + " 类型：" + str(type(float_time)))
19 # 1556254126.6432147 类型：<class 'float'>
20 
21 # 根据<class 'time.struct_time'>日期类型转换为时间戳 返回值类型<class 'float'>
22 float_time = time.mktime(time.localtime())
23 print(str(float_time) + " 类型：" + str(type(float_time)))
24 # 1556256409.0 类型：<class 'float'>
25 
26 # 根据<class 'float'>日期戳转换为struct_time日期 返回值类型<class 'time.struct_time'>
27 st_time = time.localtime(time.time())
28 print(str(st_time) + " 类型：" + str(type(st_time)))
29 # time.struct_time(tm_year=2019, tm_mon=4, tm_mday=26, tm_hour=15, tm_min=5, tm_sec=48, tm_wday=4, tm_yday=116, tm_isdst=0) 类型：<class 'time.struct_time'>
