你将浮点数转换为整数后,仍然在整数上进行了迭代操作,这可能会导致相同的错误。你可以尝试将 int(float(row[2])) 替换为 float(row[2]),这样就可以避免在整数上进行迭代操作,从而解决这个问题。
修改后的代码如下所示:
```python
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(float(row[2]))
elif row[0] > x:
break
if not neighbors:
return 0
for val in neighbors:
total += val
count += 1
return total / count
```
这样就可以避免在浮点数或整数上进行迭代操作,从而解决这个问题。

程序运行提示TypeError: 'float' object is not iterable,修改程序 if neighbors: unique_neighbors = list(set(neighbors))
看起来你已经将代码修复了,但仍存在问题。在这个代码段中,你使用了 set() 函数来将 neighbors 转换为一个集合,以去除其中的重复元素。然后,你试图将这个集合转换回列表,这个操作是不必要的。
为了解决这个问题,你可以直接对 neighbors 列表进行去重操作,并将结果保存在一个新的列表中。然后,你可以在这个新的列表上进行迭代操作,计算平均值。
修改后的代码如下所示:
```python
if neighbors:
unique_neighbors = list(set(neighbors))
avg = sum(unique_neighbors) / len(unique_neighbors)
f3.write(f'{x}\t {y}\t {avg}\n')
```
这样就可以避免在不可迭代的对象上进行迭代操作,从而解决这个问题。
zip TypeError: float object is not iterable
This error occurs when you try to iterate over a float object using a loop. A float is a numeric data type in Python that represents a decimal number. However, you cannot iterate over a float as it is not an iterable object.
For example, suppose you have a float value and you try to iterate over it using a for loop:
```
my_float = 3.14
for num in my_float:
print(num)
```
This code will result in a TypeError because you cannot iterate over a float.
To fix this error, you need to ensure that you are iterating over an iterable object, such as a list or a tuple. If you need to convert a float to an iterable object, you can do so by wrapping it in a list or tuple:
```
my_float = 3.14
my_list = [my_float]
for num in my_list:
print(num)
```
This code will iterate over the list containing the float value, rather than the float itself.
