Python:如果其他值为true，则计算嵌套字典中值的出现次数

def count_values(dictionary, count_dict):
    for value in dictionary.values():
        if isinstance(value, dict):
            count_values(value, count_dict)
        else:
            count_dict[value] = count_dict.get(value, 0) + 1

# 示例字典
nested_dict = {
    'key1': {
        'subkey1': 'value1',
        'subkey2': 'value2',
        'subkey3': {
            'subsubkey1': 'value1'
        }
    },
    'key2': {
        'subkey4': 'value3'
    }
}

# 初始化计数字典
value_counts = {}

# 调用函数计算值的出现次数
count_values(nested_dict, value_counts)

# 打印结果
for value, count in value_counts.items():
    print(f"{value}: {count}次")

value1: 2次
value2: 1次
value3: 1次
