python遍历数组的两种方法 第一种,最常用的,通过for in遍历数组
[cpp] view plain copy
colours = ["red","green","blue"] for colour in colours: print colour # red # green # blue
下面的方法可以先获得数组的长度,然后根据索引号遍历数组,同时输出索引号
[cpp] view plain copy
colours = ["red","green","blue"] for i in range(0, len(colours)): print i, colour[i] # 0 red # 1 green # 2 blue
