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()))) 12345
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)
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)) 1234567
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.')

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 parser dt = parser.parse("Aug 28 2015 12:00AM") print (dt) 123
