This error occurs when the code is trying to use a variable or class named "GoldParse" that has not been defined in the current scope or has not been imported from a module.
To fix this error, you can do one of the following:
1. Import the GoldParse class from the appropriate module using the import statement:
```python
from some_module import GoldParse
```
2. Define the GoldParse class or variable in the current scope:
```python
class GoldParse:
# class definition here
# or
gold_parse = some_value
```
Make sure to define or import the class before using it in the code.

python global name is not defined
回答: 当您在Python中遇到"Global Name 'R' is not defined"的错误时,这意味着您正在引用一个未定义的全局变量R。[1]这通常是因为您在使用该变量之前没有对其进行定义或赋值。在Python中,如果您想在函数内部使用全局变量,您需要在函数内部使用global关键字来声明该变量。如果您没有在函数内部使用global关键字声明变量R,Python会将其视为局部变量,并在使用时引发"NameError"。[2]
另外,如果您想在函数内部访问一个静态变量,您需要使用类的名称来访问它,而不是使用全局变量的名称。[3]请确保在使用全局变量之前对其进行定义和赋值,并在需要时使用global关键字声明它。这样可以避免"Global Name 'R' is not defined"错误的发生。
Python name is not defined
This error occurs when you try to use a variable or function that has not been defined in your code.
For example, if you try to print the value of a variable called "x" but you haven't assigned any value to it, you will get a "NameError: name 'x' is not defined" error.
To fix this error, make sure that all the variables and functions you are using have been defined before you try to use them.
