Python使用递归在数字字符串中计算奇数和偶数

def count_odd_even_numbers(s):
    if len(s) == 0:
        return 0, 0
    if not s[0].isdigit():
        return count_odd_even_numbers(s[1:])
    num = int(s[0])
    if num % 2 == 0:
        odd_count, even_count = count_odd_even_numbers(s[1:])
        return odd_count, even_count + 1
    else:
        odd_count, even_count = count_odd_even_numbers(s[1:])
        return odd_count + 1, even_count

# 测试示例
s = "1234567890"
odd_count, even_count = count_odd_even_numbers(s)
print("奇数个数：", odd_count)
print("偶数个数：", even_count)
