尝试运行K-Means时出现Python错误

我正在尝试编写K-means算法，我认为我已经完成了，所以我开始测试，它给了我一个错误：

File "kmeans.py", line 112, in update_clusters
    if(data[i].get_cluster() is None or data[i].get_cluster() != currrentCluster):
NameError: global name 'currrentCluster' is not defined

以下是我的更新集群定义代码：

def update_clusters():
    isStillMoving = 0

    for i in range(total_data):
        bestmin = big_num
        currentCluster = 0

        for j in range(nclusters):
            distance = get_dist(data[i].get_x(), data[i].get_y(), centroids[j].get_x(), centroids[j].get_y())
            if(distance < bestmin):
                bestmin = distance
                currentCluster = j
        data[i].set_cluster(currentCluster)

        if(data[i].get_cluster() is None or data[i].get_cluster() != currrentCluster):
            data[i].set_cluster(currentCluster)
            isStillMoving = 1

    return isStillMoving

我不知道为什么在一开始定义currentCluster时它无法识别它。任何帮助都会很好。

CurrentCluster有3个R感谢您。我知道这很简单
