用Python编写函数，接收一个字符串，分别统计大写字母、小写字母、数字、其他字符的个数，并以元组的形式返回结果

def count_chars(s):
    upper_count = 0
    lower_count = 0
    digit_count = 0
    other_count = 0
    for c in s:
        if c.isupper():
            upper_count += 1
        elif c.islower():
            lower_count += 1
        elif c.isdigit():
            digit_count += 1
        else:
            other_count += 1
    return (upper_count, lower_count, digit_count, other_count)

使用示例：

s = "Hello, World! 123"
result = count_chars(s)
print(result)  # 输出 (2, 8, 3, 4)
