"module is not defined"这个错误通常是因为在JavaScript代码中使用了module变量,但是没有在代码之前声明它。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

ArrayStack is not defined
The error message "ArrayStack is not defined" typically occurs when you are trying to use a variable or object that has not been declared or initialized in your code.
In this case, it seems that you are trying to use a class or object called "ArrayStack" but it has not been defined in your code. You need to make sure that you have imported the necessary modules or defined the class/object before using it in your code.
Here's an example of how to define an ArrayStack class in Python:
```
class ArrayStack:
def __init__(self):
self.items = []
def push(self, item):
self.items.append(item)
def pop(self):
return self.items.pop()
def is_empty(self):
return len(self.items) == 0
def size(self):
return len(self.items)
```
Make sure to import the necessary modules or define the class/object before using it in your code to avoid the "ArrayStack is not defined" error.
module is not defined
It seems like you're encountering an error stating that "module is not defined". This error typically occurs when you're trying to access a module that has not been imported or is not available within the current scope.
To resolve this issue, make sure that you have imported the required module at the beginning of your code. For example, if you're trying to use the `math` module, you can include the following line at the top of your code:
```python
import math
```
If you have already imported the module and are still getting this error, ensure that the module is installed in your Python environment. You can use the command `pip install module_name` to install missing modules.
If you're still facing issues, please provide more specific details or share your code so that I can assist you better.
