python-3.x - 收到一段代码的错误，但没有收到类似代码段的错误

Question

我一直在

TypeError：“str”对象不可调用

对于下面的函数，何时style == "scatter"而不是何时style == "categories"，我一生都无法弄清楚为什么，对我来说，何时该函数似乎应该在两个地方做同样的事情。关于我做错了什么的任何想法？

编辑：此错误发生在线路graph = graph + "\\node at (%s,%s)[circle,fill,inner sep=1pt]{};\n"(x+random.uniform(-0.5,0.5),y+random.uniform(-0.5,0.5))等
