Python获取当前时间日期的实现示例

print(time.time())

import time
start_time = time.time()
sum = 0
for i in range(1000000):
    sum += i
end_time = time.time()
print("程序执行了%f秒"%(end_time - start_time))

import time
time_tuple = time.localtime(time.time())
print("当前时间为{}年{}月{}日{}点{}分{}秒".format(time_tuple[0],time_tuple[1],time_tuple[2],time_tuple[3],time_tuple[4],time_tuple[5]))

time.asctime(time.localtime())  # 参数为时间元组
time.ctime(time.time())  # 参数为浮点数时间戳

# 格式化成2020-06-25 11:18:29形式
print(time.strftime("%Y-%m-%d %H:%M:%S",time.localtime()))
# 格式化成Thu Jun 25 11:18:29 2020形式
print(time.strftime("%a %b %d %H:%M:%S %Y",time.localtime()))

import time
# time.mktime()方法可以把时间元组转为时间戳
tuple01 = (2008,8,8,20,8,8,0,0,0)
# 待求时间戳
time01 = time.mktime(tuple01) + 88888888
# 待求时间元组
tuple02 = time.localtime(time01)
# 打印结果
print("结果:",time.strftime("%Y-%m-%d %H:%M:%S",tuple02),end="\t")
tuple_week = ("星期一","星期二","星期三","星期四","星期五","星期六","星期天")
print(tuple_week[tuple02[6]])

date01 = datetime.date.today()

print("年份",date01.year)
print("月份",date01.month)
print("日期",date01.day)

time01 = datetime.time(8,23,2,121212)

print("时",time01.hour)
print("分",time01.minute)
print("秒",time01.second)
print("微秒",time01.microsecond)

datetime01 = datetime.datetime.now()

from datetime import datetime
print(datetime.now())   # 获取当前日期时间
print(datetime.today()) # 获取当前时间
print(datetime.utcnow())    # 获取当前的格林尼治时间

from datetime import datetime
dt01 = datetime.today()
print(dt01.date())
print(dt01.time())
