变量未定义，但定义为全局变量python

Question

我不断收到错误name 'copyDir is not defined但在我的代码name 'copyDir is not defined其定义为全局变量。 怎么了？ 我在这里查看了与此类似的其他一些帖子，但仍然无法理解问题。 这是我的代码的开始部分：

import arcpy, os, shutil, re
mapIndex = r'C:\Temp\temp.gdb\MapSets_All'
copydDir = r'D:\MapSheetImages\All_Images'

fields = ['FileSpecDir','is_name']

for row in arcpy.da.SearchCursor(mapIndex,fields):
    arcpy.env.workspace = row[0]
    rstrList = arcpy.ListRasters()

    for dir, folders, files in os.walk(row[0]):
        try:
            if 'CCS27z2e' in folders:
                for r in rstrList:
                    if row[1] in r:
                        rOrigPath = os.path.join(row[0],r)
                        rNewPath = os.path.join(copyDir,r)
                        if not os.path.isfile(rNewPath):
                            arcpy.AddMessage('now copying '+r)
                            shutil.copyfile(rOrigPath,rNewPath)
        except Exception as e:
            print e
            arcpy.AddMessage(e)

您有错字：

copydDir = r'D:\MapSheetImages\All_Images'

应该：

copyDir = r'D:\MapSheetImages\All_Images'
