可以使用Python的isalpha()和isdigit()方法来统计字符串中数字和字母的个数。下面是一个示例代码：
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_counts = "Hello123"alpha_count, digit_count = count_alpha_digit(s)print(f"字母个数：{alpha_count}")print(f"数字个数：{digit_count}")运行以上代码将输出：
字母个数：5数字个数：3
