leetcode 1704. Determine if String Halves Are Alike

class Solution:
    def halvesAreAlike(self, s: str) -> bool:
        vowel=['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']
        half1=s[:len(s)//2]
        half2=s[len(s)//2:]
        half1Cnt=0
        for i in half1:
            if i in vowel: half1Cnt+=1
        half2Cnt=0
        for i in half2:
            if i in vowel: half2Cnt+=1
        if half1Cnt==half2Cnt : return True
        else: return False
