shutil ignore fails on passing a tuple?

[Alex van der Spek]

This beats me:
++++++++++++++++++++
Traceback (most recent call last):
File "<pyshell#60>", line 1, in <module>
ignorethis = igf(ddftopdir,os.listdir(ddftopdir))
File "C:\Python27\lib\shutil.py", line 138, in _ignore_patterns
ignored_names.extend(fnmatch.filter(names, pattern))
File "C:\Python27\lib\fnmatch.py", line 49, in filter
pat=os.path.normcase(pat)
File "C:\Python27\lib\ntpath.py", line 46, in normcase
return s.replace("/", "\\").lower()
AttributeError: 'tuple' object has no attribute 'replace'
set(['Chi2.png', 'DTSdata.hdf', 'TST.hdf', 'BullNoseDiffs.png',
'DTSall.hdf', 'Symmetry.pdf'])++++++++++++++++++++++++++++
Why does it fail on passing in a tuple of ignore strings? I thought the ,
(comma) is pretty much the tuple constructor (if that is the right word).

How can I solve this? Is there a way to convert a tuple of strings in a form
that will be accepted?

Thank you in advance,
Alex van der Spek

Untested, but I think it should work.
igf = shutil.ignore_patterns(*ipatterns)

What is s? It needs to be a string. If s is a tuple with string
values, you will have to iterate over each to replace. Or I believe
you could use map.

ignore_patterns() is not looking for a tuple, it's looking for one or
more strings, as separate arguments. If you already have the tuple, you
can expand it by using the asterisk, as Prasad ha pointed out.

igf = shutil.ignore_patterns(*ipatterns)
