求加权均值​的递归代码

def recursive_weighted_average(data, weights):
    if len(data) != len(weights):
        return None
    
    if len(data) == 1:
        return data[0]
    
    total_weight = sum(weights)
    weighted_sum = sum([data[i] * weights[i] for i in range(len(data))])
    average = weighted_sum / total_weight
    
    return average

data = [1, 2, 3, 4, 5]
weights = [0.1, 0.2, 0.3, 0.2, 0.2]
result = recursive_weighted_average(data, weights)
print(result)
