Python 3.x Python'；遗忘'；变量？

因此，我试图将变量写入一个单独的.txt文件，python说我的变量没有定义，尽管它在程序中使用了相同的变量

在这里，我分配并使用变量运算符_选项：

    operator_choice = input ("Ok Mate, now chose your function: multiplication, division, addition or subtraction!")        
    if operator_choice in times:
        while Question < 12:
            Mathmultiplication();
        break
    if operator_choice in division:
        while Question < 12:            
            Mathdivision();
        break
    if operator_choice in subtraction:
        while Question < 12:
            Mathsub();
        break
    if operator_choice in addition:
        while Question < 12:
            Mathadd();
        break  
    elif operator_choice not in total_difficulty:
        print ("\nNot an option, try again")

它给了我这个错误：

NameError: name 'operator_choice' is not defined

有人能告诉我发生了什么，为什么以及如何解决吗？ 这不是在函数中，而是在while循环中

完整代码如下所示：

#just some variables

在发布完整的代码之前，您无法获得完整的答案。但是，我可以为您提供一个可能的解决方案：

您在上面发布的代码位于单独的函数中，因此，

operator\u choice

的范围仅在该函数中定义。确保在函数中返回变量，或调用

结果。在该函数中写入

例如：

>>> def foo(): 
...    bar = 1 
...
>>> bar
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'bar' is not defined
>>> foo()
>>> bar
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'bar' is not defined

>>def foo（）：
...    巴=1
...
>>>酒吧
回溯（最近一次呼叫最后一次）：
文件“”，第1行，在
NameError:未定义名称“bar”
>>>foo（）
>>>酒吧
回溯（最近一次呼叫最后一次）：
文件“”，第1行，在
NameError:未定义名称“bar”
是
结果。使用与上述代码相同的功能编写
？是的，请发布一个完整的工作可复制示例：，因此完整代码已显示。有人能帮忙吗？
>>> def foo(): 
...    bar = 1 
...
>>> bar
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'bar' is not defined
>>> foo()
>>> bar
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'bar' is not defined
