可以使用Python的isalpha()和isdigit()方法來(lái)統(tǒng)計(jì)字符串中數(shù)字和字母的個(gè)數(shù)。下面是一個(gè)示例代碼：

def count_alpha_digit(s):
    alpha_count = 0
    digit_count = 0
    
    for char in s:
        if char.isalpha():
            alpha_count += 1
        elif char.isdigit():
            digit_count += 1
    
    return alpha_count, digit_count

s = "Hello123"
alpha_count, digit_count = count_alpha_digit(s)
print(f"字母?jìng)€(gè)數(shù)：{alpha_count}")
print(f"數(shù)字個(gè)數(shù)：{digit_count}")

運(yùn)行以上代碼將輸出：

字母?jìng)€(gè)數(shù)：5
數(shù)字個(gè)數(shù)：3
