Python 如果在os.walk之后文件不存在，则在何处合并？

忽略arcpy。我知道其中一些是关于python for ArcGIS的，但我的问题与python有关。如果os.walk正在处理的目录中不存在“AAA010.shp”，您将如何跳过arcpy.Merge和arcpy.Clip。当前，If和Else导致脚本跳过.merge和.clip，即使“AAA010.shp”确实存在

import os, fnmatch, arcpy

arcpy.env.workspace  =  r’C:\Users\sysadmin\desktop\datamanagement\MGCP.gdb’

fcMerged = ‘MergedFeatureClass’

fcClipped = ‘ClippedFeatureClass’

fcToClip = r’C:\Users\sysadmin\desktop\datamanagement\Country.shp’

filesMatched = list()

for root, subfolders, files in os.walk(r’C:\Users\sysadmin\desktop\datamanagement\MGCP_Raw’):

  for f in fnmatch.filer(files, ‘AAA010.shp’):
    filesMatched.append(os.path.join(root,f))

if 'AAA010.shp' in filesMatched:

   arcpy.Merge_management (filesMatched, fcMerged)

   arcpy.Clip_analysis (fcMerged, fcToClip, Extraction_Mine)

else: pass
