pythonArray filtering

本文实例讲述了python数组过滤实现方法。分享给大家供大家参考。具体如下：

这段代码可以按照指定的条件过滤数组内的元素，返回过滤后的数组

li = ["a", "mpilgrim", "foo", "b", "c", "b", "d", "d"]
print [elem for elem in li if len(elem) > 1]
print [elem for elem in li if elem != "b"]
print [elem for elem in li if li.count(elem) == 1]

希望本文所述对大家的Python程序设计有所帮助。
