AttributeError: 'int' object has no attribute 'sum

根据提供的引用内容,你遇到了一个错误:AttributeError: 'int' object has no attribute 'sum'。这个错误通常发生在你尝试在整数对象上用sum()方法时。整数对象没有sum()方法,因为sum()方法用于对可迭代对象(如列表或数组)中的元素进行求和的。
以下是一个例子演示如何使用sum()方法对列表中的元素进行求和:
```python
my_list = [1, 2, 3, 4, 5]
total = sum(my_listprint(total) # 输出:15
```
在这个例子中,定义了一个包含整数的列表my_list,并使用sum()方法对列表中的元素进行求和。最后,我们打印出求和的结果。

AttributeError: 'int' object has no attribute 'sum'
This error occurs when you try to use the sum() method on an integer object. The sum() method is used to calculate the sum of elements in an iterable object such as a list or a tuple, but it cannot be used on integers directly.
For example:
```
x = 5
total = x.sum()
```
In this case, the sum() method is being called on the integer variable x, which is not an iterable object, resulting in the AttributeError.
To fix this error, you need to use the sum() method on an iterable object that contains the integers you want to sum up. For example:
```
my_list = [1, 2, 3, 4, 5]
total = sum(my_list)
```
In this case, the sum() method is called on the list object my_list, which contains the integers 1 through 5, and returns the sum of all the elements in the list, which is 15.
AttributeError: 'bool' object has no attribute 'sum'
这个错误通常是因为你尝试在 Python 中对布尔类型的变量使用 `sum()` 函数。`sum()` 函数是用来对可迭代对象中的元素进行求和的,但是布尔类型不支持求和操作,因此会出现该错误。
请检查代码,确保你正在使用 `sum()` 函数的时候,传入的是一个可迭代对象,而不是一个布尔类型的变量。如果你想要对布尔类型的变量进行求和操作,可以将其转换为整数类型,例如:
```
a = True
b = False
total = int(a) + int(b)
print(total) # 输出 1
```
