int' object has no attribute 'isupper'

"int' object has no attribute 'isupper'"是一个错误信息，它表示整数类型的对象没有isupper()属性。isupper()是一个字符串方法，用于检查字符串中的所有字母是否都是大写字母。因此，如果你尝试在整数上调用isupper()方法，就会出现这个错误。

以下是一个例子，演示了这个错误信息的出现：

x = 123
print(x.isupper())

输出：

AttributeError: 'int' object has no attribute 'isupper'

int object has no attribute

"int object has no attribute" 的意思是 "int对象没有该属性"。这通常是因为您尝试访问一个不存在的属性或方法。可能是您的代码中有拼写错误或者您正在尝试访问一个不支持的属性或方法。请检查您的代码并确保您正在访问正确的属性或方法。

int object has no attribute pop

The error message "int object has no attribute pop" indicates that you are trying to use the pop() method on an integer object. The pop() method is a built-in method in Python that can only be used with certain data types such as lists, dictionaries, and sets.

For example, if you have a list called my_list and you want to remove the last item from it using the pop() method, you can do:

my_list = [1, 2, 3, 4, 5]
last_item = my_list.pop()

In this case, the pop() method will remove the last item from the list (5) and return it as a separate variable called last_item.

To fix the "int object has no attribute pop" error, you need to make sure that you are using the pop() method on the correct data type. If you are trying to use it on an integer or any other data type that does not support pop(), you will need to find an alternative way to achieve your desired outcome.
