笨方法学python 习题33附加练习

1.将这个while 循环改成一个函数，将测试条件(i < 6)中的6换成一个变量。
2.使用这个函数重写你的脚本，并用不同的数进行测试

def list(i):
       numbers   =  [  ]
         j  =  0
         while  j  <  i:
                   print   "At the top number is %d"  %  j
                     numbers.append(j)


           j  =  j  +  1
           print  "Number now:  ",  numbers
           print   "At the bottom number is %d" %      j
           print "The   numbers:  "
           

           for num in numbers:
                 print  num


print  "numbers:  "
i   =  int(raw_input(">"))
list(i)

3.为函数添加另外一个参数，这个参数用来定义第8行的+1,这样你就可以让它任意递增了。
4.再使用该函数重写一遍这个脚本，看看效果如何

def  list(i, z):
         numbers   =  [   ]
         j   =   0
         while   j  <  i:
                   print   "At the top  number is  %d"  %   j
                    numbers.append(j)


            j  =  j  +  z
            print  "Number  now:  ",  numbers
            print  "At the bottom  number is %d"  %  j
            print  "The numbers:  "
             for num  in  numbers:
                   print  num

print   "number:  "
i  =  int(raw_input(">"))
print  "number:  "
z  =  int(raw_input(">"))
list(i,  z)

5.接下来使用for 循环和range把这个脚本再写一遍。还需要中间的递增操作吗？如果不去掉它，会有什么样的结果？

def  list(i):
         numbers   =   [  ]
          for  j  in   range(0, i):
                  print   "At the top  number  is %d"  %  j
                    numbers.append(j)
                   print  "Numbers  now:  ",  numbers
                   print  "At the  bottom  number  is  %d"  %   j
                   print  "The number:  "
                   for num in numbers:
                         print  num
print  "number:  "
i =  int(raw_input(">"))
list(i)
