如果os.walk之后文件不存在，则在哪里合并IF和Else？

Question

忽略arcpy。 我知道其中一些涉及Python for ArcGIS，但我的问题是与python有关。 如果os.walk正在通过的目录中不存在“ AAA010.shp”，则如何跳过arcpy.Merge和arcpy.Clip。 当前，即使'AAA010.shp'存在，If and Else也会导致脚本跳过.merge和.clip。

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
