Arcmap 脚本不会在 arcmap 控制台中打印消息

Question

我有一个我为 Arcmap 编写的 Python 脚本。我正在尝试创建一个工具，将工作区内的所有特征 classes 重新投影到指定的特征 class。

我遇到的问题是我无法让 Arcmap 打印 "completed" 消息。当我对变量进行硬编码并将其运行作为脚本时，我想要显示的消息将打印出来，但它们不会在 Arcmap 中打印出来。您可以在下面的代码中看到我想要打印特定的打印消息，但它们不会出现。

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，不会打印以下行（来自上面的代码）：

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"

我该如何解决这个问题？

print 仅在您的脚本在 Python 解释器中运行时打印消息。为了在 ArcGIS Toolbox 中脚本为运行时打印日志，您需要使用 arcpy.AddMessage()

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