import time

#1.  获取当前时间的struct格式

struct_time = time.localtime()

print(struct_time) #time.struct_time(tm_year=2019, tm_mon=12, tm_mday=24, tm_hour=22, tm_min=22, tm_sec=44, tm_wday=1, tm_yday=358, tm_isdst=0)

# 可以很方便的获取年月日时分秒等信息

print(struct_time.tm_year)

print(struct_time.tm_mon)

#2.  将struct_time 进行格式化

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

print(str_time) #2019-12-24 22:22:44

#3. 将格化式的时间字符串转成时间戳

time_array = time.strptime('2019-12-24 22:22:44','%Y-%m-%d %H:%M:%S')

timestamp = int(time.mktime(time_array))

print(timestamp)  #

# 直接生成时间戳的方式

time_stamp = time.time()

print(time_stamp)  #1577198427.3533304

# 将时间戳转换成struct_time, 然后就可以再将struct_time 转成字符串

struct_time = time.localtime(1577198427.3533304)

print(struct_time)

# 4. 时间字符串格式转换

a2 = "2019/5/10 23:40:00"

time_array = time.strptime(a2,'%Y/%m/%d %H:%M:%S')

other_style_time =  time.strftime('%Y-%m-%d %H-%M-%S',time_array)

# other_style_time =  time.strftime('%Y-%m-%d %X',time_array)

print(other_style_time)  # 2019-05-10 23:40:00

# 5.生成格式威治时间

#  time.gmtime()与time.localtime()没看到区别呀

m_time = time.gmtime()

print(m_time)

local_time = time.localtime()

print(local_time)

print(time.asctime())  #Tue Dec 24 22:46:55 2019

print(time.ctime(time.time()))  # Tue Dec 24 22:46:55 2019

# time 加减

t1 =  time.time()

t2 = t1 +10  # 加上10秒钟

print(time.ctime(t1))  # Tue Dec 24 22:48:18 2019

print(time.ctime(t2))  # Tue Dec 24 22:48:28 2019
