实例091：time模块

题目：时间函数举例1。

程序分析：无。

if __name__ == '__main__': import time print (time.ctime(time.time())) print (time.asctime(time.localtime(time.time()))) print (time.asctime(time.gmtime(time.time())))

实例092：time模块II

题目：时间函数举例2。

程序分析：如何浪费时间。

if __name__ == '__main__':    import time    start = time.time()    for i in range(3000):        print(i)    end = time.time()     print (end - start)

实例093：time模块III

题目：时间函数举例3。

程序分析：如何浪费时间。

if __name__ == '__main__': import time start = time.clock() for i in range(100): print(i) end = time.clock() print('different is %6.3f' % (end - start))

实例094：time模块IV

题目：时间函数举例4。

程序分析：如何浪费时间。

if __name__ == '__main__':    import time    import random        play_it = input('do you want to play it.(\'y\' or \'n\')')    while play_it == 'y':        c = input('input a character:\n')        i = random.randint(0,2**32) % 100        print ('please input number you guess:\n')        start = time.clock()        a = time.time()        guess = int(input('input your guess:\n'))        while guess != i:            if guess > i:                print('please input a little smaller')                guess = int(input('input your guess:\n'))            else:                print('please input a little bigger')                guess = int(input('input your guess:\n'))        end = time.clock()        b = time.time()        var = (end - start) / 18.2        print (var)        # print 'It took you %6.3 seconds' % time.difftime(b,a))        if var < 15:            print ('you are very clever!')        elif var < 25:            print ('you are normal!')        else:            print ('you are stupid!')        print ('Congradulations')        print ('The number you guess is %d' % i)        play_it = input('do you want to play it.')

实例095：转换时间格式

题目：字符串日期转换为易读的日期格式。

程序分析：看看就得了，dateutil是个第三方库。

from dateutil import parserdt = parser.parse('Aug 28 2015 12:00AM')print (dt)
