2.程序源代码:
'''
if __name__ == '__main__':
    import time
    start = time.time()
    for i in range(3000):

    print 'different is %6.3f' % (end - start)
    

'''
【程序94】
题目:时间函数举例4,一个猜数游戏,判断一个人反应快慢。(版主初学时编的)
1.程序分析:
2.程序源代码:
'''
if __name__ == '__main__':
    import time
    import random
    
    play_it = raw_input('do you want to play it.(\'y\' or \'n\')')
    while play_it == 'y':
        c = raw_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(raw_input('input your guess:\n'))
        while guess != i:
            if guess > i:
                print 'please input a little smaller'
                guess = int(raw_input('input your guess:\n'))
            else:
                print 'please input a little bigger'
                guess = int(raw_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 = raw_input('do you want to play it.')
        

'''
【程序96】
题目:计算字符串中子串出现的次数
1.程序分析:
2.程序源代码:
'''
if __name__ == '__main__':
    str1 = raw_input('input a string:\n')
    str2 = raw_input('input a sub string:\n')
    ncount = str1.count(str2)
    print ncount 

'''
【程序97】
题目:从键盘输入一些字符,逐个把它们送到磁盘上去,直到输入一个#为止。
1.程序分析:     
2.程序源代码:
'''
if __name__ == '__main__':
    from sys import stdout
    filename = raw_input('input a file name:\n')
    fp = open(filename,"w")
    ch = raw_input('input string:\n')
    while ch != '#':
        fp.write(ch)
        stdout.write(ch)
        ch = raw_input('')
    fp.close()
        

'''
【程序98】
题目:从键盘输入一个字符串,将小写字母全部转换成大写字母,然后输出到一个磁盘文件“test”中保存。
   输入的字符串以!结束。 
1.程序分析:
2.程序源代码:
'''
if __name__ == '__main__':
    fp = open('test.txt','w')
    string = raw_input('please input a string:\n')
    string = string.upper()
    fp.write(string)
    fp = open('test.txt','r')
    print fp.read()
    fp.close()

'''
程序99】
题目:有两个磁盘文件A和B,各存放一行字母,要求把这两个文件中的信息合并(按字母顺序排列), 
 输出到一个新文件C中.
1.程序分析:
2.程序源代码:
'''
if __name__ == '__main__':
    import string
    fp = open('JCP099.py')
    a = fp.read()
    fp.close()

    fp = open('JCP098.py')
    b = fp.read()
    fp.close()

    fp = open('C.txt','w')
    l = list(a + b)
    l.sort()
    s = ''
    s = s.join(l)
    fp.write(s)
    fp.close()
