如何从Python函数返回多个值的不同计数

def count_values(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return count_a, count_b

result = count_values("aabbbcc")
print(result)  # 输出: (2, 3)

def count_values(data):
    counts = {'a': data.count('a'), 'b': data.count('b')}
    return counts

result = count_values("aabbbcc")
print(result)  # 输出: {'a': 2, 'b': 3}

class CountResult:
    def __init__(self, count_a, count_b):
        self.count_a = count_a
        self.count_b = count_b

def count_values(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return CountResult(count_a, count_b)

result = count_values("aabbbcc")
print(result.count_a, result.count_b)  # 输出: 2 3

from collections import namedtuple

CountResult = namedtuple('CountResult', ['count_a', 'count_b'])

def count_values(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return CountResult(count_a, count_b)

result = count_values("aabbbcc")
print(result.count_a, result.count_b)  # 输出: 2 3

from collections import namedtuple

# 使用元组
def count_values_tuple(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return count_a, count_b

# 使用字典
def count_values_dict(data):
    counts = {'a': data.count('a'), 'b': data.count('b')}
    return counts

# 使用类实例
class CountResult:
    def __init__(self, count_a, count_b):
        self.count_a = count_a
        self.count_b = count_b

def count_values_class(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return CountResult(count_a, count_b)

# 使用命名元组
CountResultTuple = namedtuple('CountResult', ['count_a', 'count_b'])

def count_values_namedtuple(data):
    count_a = data.count('a')
    count_b = data.count('b')
    return CountResultTuple(count_a, count_b)

# 测试函数
data = "aabbbcc"
print(count_values_tuple(data))  # 输出: (2, 3)
print(count_values_dict(data))   # 输出: {'a': 2, 'b': 3}
print(count_values_class(data).count_a, count_values_class(data).count_b)  # 输出: 2 3
print(count_values_namedtuple(data).count_a, count_values_namedtuple(data).count_b)  # 输出: 2 3
