Python数组遍历的简单实现方法小结

 > os.__file__.split('\\')
['E:', 'Python', 'Python25', 'lib', 'os.pyc']
> os.path.split(os.__file__)
('E:\\Python\\Python25\\lib', 'os.pyc')

var myArr:Array = new Array("one", "two", "three");
var myStr:String = myArr.join(" and ");
trace(myArr); // one,two,three
trace(myStr); // one and two and three

for item in sequence:
process(item)

for index in range(len(sequence)):
process(sequence[index])

for index, item in enumerate(sequence):
process(index, item)
