python for 循环

python for 循环用法：

for iter_var in iterable
   suite_to_repeat

每次循环，iter_var 迭代变量被设置为可迭代对象（序列、迭代器或其它支持迭代的对象）的当前元素，提供给suite_to_repeat 语句块使用。

语言晦涩难懂，看个例子吧：

>>> for eachletter in 'Names':
	print 'current letter:', eachletter

	
current letter: N
current letter: a
current letter: m
current letter: e
current letter: s

>>> nameList = ['Walter', 'Nice', 'Steven']
>>> for eachname in nameList:
    print eachname, "Lim"

    
Walter Lim
Nice Lim
Steven Lim
>>>
