如何对字典中的值进行平均？

def average_values(dictionary):
    values = dictionary.values()
    total = sum(values)
    count = len(values)
    average = total / count
    return average

# 示例字典
my_dict = {'a': 10, 'b': 20, 'c': 30}

# 调用函数计算平均值
result = average_values(my_dict)
print("平均值为:", result)

平均值为: 20.0
