My understanding was that rmtree removes a whole tree not just the
empty directories?
eg.
root
- file1
- file2
- dir1
- dir2
- file3
- dir3
I would expect; dir1 and dir3 to be deleted and nothing else touched.
My attempt came up with:
import os
import shutil
def isDirEmpty( path ):
if not os.path.isdir( path ):
return False
contents = os.listdir( path )
if len(contents) == 0:
return True
return False
def RecurseTree( path ):
if not os.path.isdir( path ):
return False
contents = os.listdir( path )
if len(contents) == 0:
print "Deleting Empty Dir '%s'" % (path,)
#shutil.rmtree(path)
else:
for item in contents:
investigate = "%s\\%s" % (path, item)
if os.path.isdir(investigate):
RecurseTree( investigate )
if __name__ == '__main__':
RecurseTree( r"c:\temp" )
But I'm not sure what the max recursion depth is in python? Plus I
think this could be more efficient.
