Arcmap脚本不会在Arcmap cons中打印消息

Question

我为Arcmap编写了一个Python脚本。我正在尝试创建一个工具，将工作区中的所有要素类重新投影到指定的要素类。你知道吗

我遇到的问题是无法让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，我有我想要打印的特定打印消息，但是它们不会出现。你知道吗

代码：

#Import modules
import arcpy, os

#Set workspace directory
from arcpy import env

#Define workspace
inWorkspace = arcpy.GetParameterAsText(0)
env.workspace = inWorkspace
env.overwriteOutput = True

try:
    #Define local feature class to reproject to:
    targetFeature = arcpy.GetParameterAsText(1)

    #Describe the input feature class
    inFc = arcpy.Describe(targetFeature)
    sRef = inFc.spatialReference

    #Describe input feature class
    fcList = arcpy.ListFeatureClasses()

    #Loop to re-define the feature classes and print the messages:
    for fc in fcList:
        desc = arcpy.Describe(fc)
        if desc.spatialReference.name != sRef.name:
            print "Projection of " + str(fc) + " is " + desc.spatialReference.name + ", so re-defining projection now:\n"
            newFc = arcpy.Project_management(fc, "projected_" + fc, sRef)
            newFeat = arcpy.Describe(newFc)
            count = arcpy.GetMessageCount()
            print "The reprojection of " + str(newFeat.baseName) + " " + arcpy.GetMessage(count-1) + "\n"

    #Find out which feature classes have been reprojected
    outFc = arcpy.ListFeatureClasses("projected_*")

    #Print a custom messagae describing which feature classes were reprojected
    for fc in outFc:
        desc = arcpy.Describe(fc)
        name = desc.name
        name = name[:name.find(".")]
    name = name.split("_")
    name = name[1] + "_" + name[0]
    print "The new file that has been reprojected is named " + name + "\n"

except arcpy.ExecuteError:
    pass

severity = arcpy.GetMaxSeverity()

if severity == 2:
    print "Error occurred:\n{0}".format(arcpy.GetMessage(2))
elif severity == 1:
    print "Warning raised:\n{1}".format(arcpy.GetMessage(1))
else:
    print "Script complete"

当我将脚本上传到Arcmap工具箱时，以下行（来自上面的代码）将不会打印：

print "Projection of " + str(fc) + " is " + desc.spatialReference.name + ", so re-defining projection now:\n"

print "The reprojection of " + str(newFeat.baseName) + " " + arcpy.GetMessage(count-1) + "\n"

print "The new file that has been reprojected is named " + name + "\n"

我怎样才能解决这个问题？你知道吗

print仅在脚本在Python解释器中运行时打印消息。为了在脚本在ArcGIS工具箱中运行时打印日志，需要使用^{}

arcpy.AddMessage("Projection of {0} is {1}, so re-defining projection now: ".format(str(fc), desc.spatialReference.name)
