    打印出1到100的数，不包含100

    for i in range(1,100):

    if i==23:

    print "great,you got your luncky number:",i

    print 'The unmber is:',i

    ================23会被重复打印===============================



    for i in range(1,100):

        if i==23:

               print "great,you got your luncky number:",i

        else:

               print "The unmber is:",i

    ================23只会打印一次===============================



    for i in range(1,100):

    if i==23:

    print "great,%s lucky number:"%i  #%s，引用外部的变量；外部的变量则为：引号之外的变量

    print "The number is:",i
