Question

我已经阅读了该问题的所有先前实例，并尝试了多种解决方法。我已经确定空格不是使用notepad ++的制表符，并且我尝试检查语法错误，但找不到任何内容。我究竟做错了什么。我正在尝试从GitHub存储库中运行此代码，尽管我对此很陌生。有很多错误，但是当我遇到这些错误时，我正在尝试解决它们。使我陷入困境的是以下内容：

if(x_dimension_variable==y_dimension_variable):   File "<stdin>", line 1
     if(x_dimension_variable==y_dimension_variable):
    ^ IndentationError: unexpected indent

这是代码
