检查数组是否在Python中包含递增元素 [英] Check if array contains incrementing elements in Python

问题描述

我想检查Python中的数组是否包含递增元素，每个元素递增1，并从0开始. [0, 1, 2, 3]应该返回"valid"，而例如[0, 1, 3, 4]或[-1, 0, 1]应该返回无效".

I want to check if an array in Python contains incrementing elements, incremented by one each and starting with 0. So, e.g. [0, 1, 2, 3] should return "valid", whereas e.g. [0, 1, 3, 4] or [-1, 0, 1] should return "not valid".

有没有一种简单的方法可以在Python中实现?也许是内置功能?

Is there an easy way to achieve that in Python? Maybe an built-in function?

推荐答案

如果问题确实如您所描述，则可以使用range轻松解决，就像这样:

If the problem is truly as you describe it, this can be solved trivially using range, like so:

myList = [...]
if myList == list(range(myList[-1] + 1)):
    # Do stuff.
