Python Arcmap脚本不会在Arcmap控制台中打印消息

我为Arcmap编写了一个Python脚本。我试图创建一个工具，将工作区中的所有要素类重新投影到指定的要素类

我遇到的问题是，我无法让Arcmap打印“已完成”的消息。当我硬编码变量并将其作为脚本运行时，我希望显示的消息将打印出来，但它们不会在Arcmap中打印。你可以在下面的代码中看到，我有一些我想要打印的特定打印消息，但它们就是不会出现

代码：

当我将脚本上载到Arcmap工具箱时，将不会打印以下行（来自上述代码）：

print“+str（fc）+”的“投影”是“+desc.spatialReference.name+”，因此现在重新定义投影：\n“

打印“+str（newFeat.baseName）+”+arcpy.GetMessage（count-1）+”\n”的重投影

print“重新投影的新文件名为“+name+”\n”

如何修复此问题？
print
仅在脚本在Python解释器中运行时打印消息。要在ArcGIS工具箱中运行脚本时打印日志，需要使用

我怀疑IDLE与此有关，但为了确保这一点，请直接使用python运行脚本，而不涉及IDLE。
