题目如下：

Given an integer array arr, return true if there are three consecutive odd numbers in the array. Otherwise, return false.

Example 1:

Input: arr = [2,6,4,1]
Output: false
Explanation: There are no three consecutive odds.

Example 2:

Input: arr = [1,2,34,3,4,5,7,23,12]
Output: true
Explanation: [5,7,23] are three consecutive odds. 

Constraints:

• 1 <= arr.length <= 1000
• 1 <= arr[i] <= 1000

解题思路：送分题。

代码如下：

class Solution(object):
    def threeConsecutiveOdds(self, arr):
        """
        :type arr: List[int]
        :rtype: bool
        """
        res = False
        for i in range(len(arr)-2):
            if arr[i] % 2 == 1 and arr[i+1] % 2 == 1 and arr[i+2] % 2 == 1:
                return True
        return res
