""" enumerate(iterable[, start]) -> iterator for index, value of iterable Return an enumerate object. iterable must be another object that supports iteration. The enumerate object yields pairs containing a count (from start, which defaults to zero) and a value yielded by the iterable argument. enumerate is useful for obtaining an indexed list: (0, seq[0]), (1, seq[1]), (2, seq[2]),"""#enumerate()a = [1,2,3,4,5,6,7,8,9,1,2,3,4,56,6]for k, v in enumerate(a): if v == 4: print k312
enumerate方法是把list里面的下标和元素组成一个元组并返回一个枚举对象代码里面的k从0开始每一项加1这样就可以找到重复元素的位置，然后取到该重复元素
