《笨办法学python》加分习题33——我的答案

这是我自己学习的答案，会尽力写的比较好。还望大家能够提出我的不足和错误，谢谢！

**

原文例题：

**

i = 0
numbers =[]

while i < 6:
print "At the top i is %d" % i
numbers.append(i)

i += 1

print "Numbers now: ", numbers
print "At the bottom i is %d" % i

print "The numbers: "

for num in numbers:
print num

**

习题答案：

1、

def loop(bout):

i = 0
numbers =[]

while i < bout:
print "At the top i is %d" % i
numbers.append(i)

i += 1

print "Numbers now: ", numbers
print "At the bottom i is %d" % i

print "The numbers: "

for num in numbers:
print num

2、

import ex33

ex33.loop(6)
print "\n"
ex33.loop(4)

3、

def loop(bout):

i = 0
numbers =[]

while i < bout:
print "At the top i is %d" % i
numbers.append(i)

temp = i + 1

print "Numbers now: ", numbers
print "At the bottom i is %d" % temp

print "The numbers: "

for num in numbers:
print num

4、一样的

5、

def loop(bout):

numbers = []
for number in range(0, bout):
numbers.append(number)
print "Numbers now: ", numbers

loop(5)

运行结果：



一开始我的for-loop是这样写的：

for number in bout:

然后就一直报错：

int' object is not iterable

说是int不能用来迭代，我就去翻看前面的练习和和上网找资料，最后使用的是将bout通过range改为list。

在此感谢：惹不起的程咬金，我在这里得到解释和答案。
