Question

逗人，

我是一名研究生，也是spyder软件的新用户。

我正在通过python语言编程使用这个程序，并且我通过很长的路来学习python和spyder以便能够插入我的代码。

但是我遇到了一些错误，我试图解决它并且我成功但其中一些我尝试但我不知道问题是什么。

所以，我很高兴有这个庞大的社区来问像你这样受尊敬的专家，我希望支持我解决这个问题，因为我没有任何导游在我的大学里知道这个软件。

等式＃2中的错误

for b in range(1,3):
    #create constraints
m.addConstr(quicksum(x[b,j,t] <=1 for j in J for t in range(r[b],(d[b]-p[b]+1))),name="block_allocation")    #eqution 2

出现的错误是

>>> runfile('C:/Users/Ahmed/AppData/Roaming/Microsoft/Windows/Network Shortcuts/operating_roomintegrated.py', wdir='C:/Users/Ahmed/AppData/Roaming/Microsoft/Windows/Network Shortcuts')

Traceback (most recent call last):

作为Python编程的一般建议，请始终注意编译器错误，尤其是堆栈跟踪的最后几行：

IndentationError ：预计会出现缩进块

请检查您的代码：您有一些缩进问题，对于Python来说是严重，因为它划分了范围（您可能对this answer感兴趣）。

另外，正如您所说的使用Spyder，您可以尝试运行：来源 - ＆gt;修复缩进，删除尾随空格。
