Special Array I.py

'''
An array is considered special if every pair of its adjacent elements contains two numbers with different parity.

You are given an array of integers nums. Return true if nums is a special array, otherwise, return false.

my code:
class Solution:
    def isArraySpecial(self, nums: List[int]) -> bool:
        n = len(nums)
        st = True
        for i in range(n-1):
            cur = nums[i]
            next= nums[i+1]
            if (cur%2 == 0 and next%2 == 1) or (cur%2 == 1 and next%2 == 0):
                continue
            else:
                st = False
        return st
