如何在Python中计算元音和辅音

import re

def count_vowels_consonants(s):
    # 将字符串转换为小写，以便统一处理
    s = s.lower()
    
    # 定义元音字母集合
    vowels = set("aeiou")
    
    # 初始化元音和辅音计数器
    vowel_count = 0
    consonant_count = 0
    
    # 遍历字符串中的每个字符
    for char in s:
        if char.isalpha():  # 检查字符是否为字母
            if char in vowels:
                vowel_count += 1
            else:
                consonant_count += 1
    
    return vowel_count, consonant_count

# 示例字符串
input_string = "Hello World"

# 计算元音和辅音数量
vowels, consonants = count_vowels_consonants(input_string)

print(f"元音数量: {vowels}")
print(f"辅音数量: {consonants}")
