“术语未定义”或“无效语法”或 [英] "term not defined" or "invalid syntax"
问题描述
你好，
我是Python课程的第一学期计算机科学专业的学生。我们当前的分配要求我们从文件中读取列表，从文件创建二维列表，并检查2-dim列表是否构成魔术方块。 （即，添加时所有行，列和对角线彼此相等）。我们要创建几个定义，我从文件中读取，创建列表，获取第一行的总和没有问题。我需要做的下一件事是总结其他行，看看它们是否等于第一行。如果不相等，我返回false并且函数结束，如果全部相等，则返回True。当我尝试在我的areRowSumsEqualToSum中调用另一个函数（def sum（list，dimensions））时功能，我收到一条消息，告诉我术语尺寸。未定义，即使我在def sum（list，dimensions）中使用相同的术语。功能。当我尝试在定义名称中调用sum（list，dimensions）时，我得到一个无效语法。错误。
列表文件如下所示，第一行是square的尺寸，列表后面跟着一个空格。

Hello,
I am a 1st semester Computer Science student in a Python class. Our current assignment calls for us to read a list from a file, create a 2-dimensional list from the file, and check to see whether or not 2-dim list constitutes a "magic square" (i.e. all the rows, columns and diagonals equal each other when added). We are to create several definitions, and I have had no problem reading from the file, creating the list, and getting the sum of the first row. The next thing I need to do is sum up the other rows and see if they are equal to the first row. If not equal, I return a false and the function ends, if all are equal, I return a True. When I try to call another function (def sum(list, dimensions)) in my "areRowSumsEqualToSum" function, I am getting a message telling me that the term "dimensions" is not defined, even though i use the same term in the "def sum(list, dimensions)" function. When I try to call sum(list, dimensions) in the definition name, I get an "invalid syntax" error.
The list file looks like this, the first line is the dimensions of the "square", with the list following after a blank space.

Here is my code, I appreciate any help, and I apologize if this is a mess. I''m pretty green still.
推荐答案
我不能由于系统中的错误，请在此处引用您的代码，但这应该有所帮助：
I can''t quote your code here due to a bug in the system, but this should help:
编辑：我想缩进不会显示在这里？
edit: i guess the indents don''t show up here?
我添加了所谓的代码标签。发布或回复时，说明在右侧。
我已经标记了您的提交，但没有测试任何东西。
我不能强调这一点：评论一切。从长远来看，你会更喜欢自己，并且从别人那里获得帮助变得更容易。
玩得开心：
I''ve added what are called code tags. Instructions are on the right hand side while posting or replying.
I''ve marked up your submission, but haven''t tested any thing.
I can''t stress this enough: Comment everything. You''ll like yourself much more in the long run and getting help from others becomes easier, as well.
Have fun:
感谢您的回复bartonc。我现在得到这个错误：
Thanks for the reply bartonc. I now get this error:
