Do you have these two files, os.py and plan9.py,
in /sys/lib/python?
# To unbundle, run this file
echo os.py
sed 's/.//' >os.py <<'//GO.SYSIN DD os.py'
-r"""OS routines for Mac, DOS, NT, or Posix depending on what system we're on.
-
-This exports:
- - all functions from posix, nt, dos, os2, mac, or ce, e.g. unlink, stat, etc.
- - os.path is one of the modules posixpath, ntpath, macpath, or dospath
- - os.name is 'posix', 'nt', 'dos', 'os2', 'mac', 'ce', 'riscos', or 'plan9'
- - os.curdir is a string representing the current directory ('.' or ':')
- - os.pardir is a string representing the parent directory ('..' or '::')
- - os.sep is the (or a most common) pathname separator ('/' or ':' or '\\')
- - os.extsep is the extension separator ('.' or '/')
- - os.altsep is the alternate pathname separator (None or '/')
- - os.pathsep is the component separator used in $PATH etc
- - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n')
- - os.defpath is the default search path for executables
-
-Programs that import and use 'os' stand a better chance of being
-portable between different platforms. Of course, they must then
-only use functions that are defined by all platforms (e.g., unlink
-and opendir), and leave all pathname manipulation to os.path
-(e.g., split and join).
