It's because arcpy is wrapping single quotes around the file path. print repr(Layer) >>> u"'C:\\WorkSpace\\test workspace\\test.shp'" This works: import arcpy, os  #Read input parameters from script tool LayersList = arcpy.GetParameterAsText(0).split(";")  # Process: Add Field for Layer in LayersList:     arcpy.AddMessage(repr(Layer))     arcpy.AddField_management(Layer.strip("'"), "DUP", "DOUBLE", 9, "", "", "Dup", "NULLABLE") ...

The zipfile module is pure python. Get a copy of zipfile.py from python 2.6, rename it and distribute it with your own scripts. E.g. (assuming it is saved as zipfile26.py in the same directory as your code): import zipfile26 z = r"C:\zipfile.zip" zf = zipfile26.ZipFile(z, 'r') zf.extractall(etc...) You could also try subclassing ZipFile (2.5) and adding the extract, extractall and _extract_member methods copied from the 2.6 ZipFile class. Completely untested but something like the following *might* work... import zipfile,os,shutil  class ZipFile26(zipfile.ZipFile):          def extract(self, member, path=None, pwd=None):         """Extract a member from the archive to the current working directory,            using its full name. Its file information is extracted as accurately            as possible. `member' may be a filename or a ZipInfo object. You can            specify a different directory using `path'.         """         if not isinstance(member, zipfile.ZipInfo):             member = self.getinfo(member)          if path is None:             path = os.getcwd()          return self._extract_member(member, path, pwd)      def extractall(self, path=None, members=None, pwd=None):         """Extract all members from the archive to the current working            directory. `path' specifies a different directory to extract to.            `members' is optional and must be a subset of the list returned            by namelist().         """         if members is None:             members = self.namelist()          for zipinfo in members:             self.extract(zipinfo, path, pwd)      def _extract_member(self, member, targetpath, pwd):         """Extract the ZipInfo object 'member' to a physical            file on the path targetpath.         """         # build the destination pathname, replacing         # forward slashes to platform specific separators.         # Strip trailing path separator, unless it represents the root.         if (targetpath[-1:] in (os.path.sep, os.path.altsep)             and len(os.path.splitdrive(targetpath)[1]) > 1):             targetpath = targetpath[:-1]          # don't include leading "/" from file name if present         if member.filename[0] == '/':             targetpath = os.path.join(targetpath, member.filename[1:])         else:             targetpath = os.path.join(targetpath, member.filename)          targetpath = os.path.normpath(targetpath)          # Create all upper directories if necessary.         upperdirs = os.path.dirname(targetpath)         if upperdirs and not os.path.exists(upperdirs):             os.makedirs(upperdirs)          if member.filename[-1] == '/':             if not os.path.isdir(targetpath):                 os.mkdir(targetpath)             return targetpath          source = self.open(member, pwd=pwd)         target = file(targetpath, "wb")         shutil.copyfileobj(source, target)         source.close()         target.close()          return targetpath ...

No, raw strings only apply to string literals not string variables.  You just need to quote your expression as you would entering it manually in the field calculator: arcpy.CalculateField_management(fc, fld, '"'+case_number+'"') #Or arcpy.CalculateField_management(fc, fld, '"%s"' % case_number) ...
