程序运行提示TypeError: 'float' object is not iterable，def search_neighborhood(x, y): neighbors = [] total = 0 count = 0 for line in lines2: row = line.split() if row[0] == x and row[1] == y: neighbors.append(int(float(row[2]))) elif row[0] > x: break if not neighbors: return 0 for val in neighbors: total += val count += 1 return total / countdef search_neighborhood(x, y): neighbors = [] total = 0 count = 0 for line in lines2: row = line.split() if row[0] == x and row[1] == y: neighbors.append(int(float(row[2]))) elif row[0] > x: break if not neighbors: return 0 for val in neighbors: total += val count += 1 return total / count

这个错误通常表示你尝试迭代一个浮点数或其他非迭代对象。在你的代码中，`TypeError` 是由以下这一行代码引起的：

for val in neighbors:

这表明 `neighbors` 是一个浮点数或其他非迭代对象。

在你的代码中，`neighbors` 是一个空列表，它只在符合条件时添加元素。因此，如果没有符合条件的元素，`neighbors` 将保持为空列表。你可以在函数的末尾添加一个条件来检查 `neighbors` 是否为空，如果是，则返回 0。例如：

def search_neighborhood(x, y):
    neighbors = []
    total = 0
    count = 0
    for line in lines2:
        row = line.split()
        if row[0] == x and row[1] == y:
            neighbors.append(int(float(row[2])))
        elif row[0] > x:
            break
    if not neighbors:
        return 0
    for val in neighbors:
        total += val
        count += 1
    return total / count

这样，如果 `neighbors` 为空列表，函数将返回 0，否则将计算平均值并返回。
