This exports: - all functions from posix or nt, e.g. unlink, stat, etc. - os.path is either posixpath or ntpath - os.name is either 'posix' or 'nt' - os.curdir is a string representing the current directory (always '.') - os.pardir is a string representing the parent directory (always '..') - os.sep is the (or a most common) pathname separator ('/' or '\\') - os.extsep is the extension separator (always '.') - 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 - os.devnull is the file path of the null device ('/dev/null', etc.) 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).

For each directory in the directory tree rooted at top (including top itself, but excluding '.' and '..'), yields a 3-tuple dirpath, dirnames, filenames dirpath is a string, the path to the directory. dirnames is a list of the names of the subdirectories in dirpath (excluding '.' and '..'). filenames is a list of the names of the non-directory files in dirpath. Note that the names in the lists are just names, with no path components. To get a full path (which begins with top) to a file or directory in dirpath, do os.path.join(dirpath, name). If optional arg 'topdown' is true or not specified, the triple for a directory is generated before the triples for any of its subdirectories (directories are generated top down). If topdown is false, the triple for a directory is generated after the triples for all of its subdirectories (directories are generated bottom up). When topdown is true, the caller can modify the dirnames list in-place (e.g., via del or slice assignment), and walk will only recurse into the subdirectories whose names remain in dirnames; this can be used to prune the search, or to impose a specific order of visiting. Modifying dirnames when topdown is false has no effect on the behavior of os.walk(), since the directories in dirnames have already been generated by the time dirnames itself is generated. No matter the value of topdown, the list of subdirectories is retrieved before the tuples for the directory and its subdirectories are generated. By default errors from the os.scandir() call are ignored. If optional arg 'onerror' is specified, it should be a function; it will be called with one argument, an OSError instance. It can report the error to continue with the walk, or raise the exception to abort the walk. Note that the filename is available as the filename attribute of the exception object. By default, os.walk does not follow symbolic links to subdirectories on systems that support them. In order to get this functionality, set the optional argument 'followlinks' to true. Caution: if you pass a relative pathname for top, don't change the current working directory between resumptions of walk. walk never changes the current directory, and assumes that the client doesn't either. Example: import os from os.path import join, getsize for root, dirs, files in os.walk('python/Lib/email'): print(root, "consumes", end="") print(sum([getsize(join(root, name)) for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories NFT) fspathrArSnext StopIterationis_dirappendr is_symlinkr islinkjoinwalk)toptopdownonerror followlinksdirsnondirs walk_dirs scandir_iterrorentryr` walk_intorbrcrddirnamenew_pathrrrres`;            re.)follow_symlinksdir_fdccst|trt|dst|}|s.t|d|d}t|t|d}zB|s^t|j r|t |t|r|t ||t|t |||EdHWdt|XdS)aDirectory tree generator. This behaves exactly like walk(), except that it yields a 4-tuple dirpath, dirnames, filenames, dirfd `dirpath`, `dirnames` and `filenames` are identical to walk() output, and `dirfd` is a file descriptor referring to the directory `dirpath`. The advantage of fwalk() over walk() is that it's safe against symlink races (when follow_symlinks is False). If dir_fd is not None, it should be a file descriptor open to a directory, and top should be relative; top will then be relative to that directory. (dir_fd is always supported for fwalk.) Caution: Since fwalk() yields file descriptors, those are only valid until the next iteration step, so you should dup() them if you want to keep them for a longer period. Example: import os for root, dirs, files, rootfd in os.fwalk('python/Lib/email'): print(root, "consumes", end="") print(sum([os.stat(name, dir_fd=rootfd).st_size for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories __index__F)rtru)ruN)rQinthasattrr]r3r9O_RDONLYstS_ISDIRst_moder samestat_fwalkrRclose)rfrgrhrtruorig_sttopfdrrrfwalks!rc cst|}g}g}|s|rdng} x|D]} | j} |ry|j||}Wntk r2t|dYnX||S)N)rrrr)rkeyvaluerrr __getitem__s z_Environ.__getitem__cCs.||}||}|||||j|<dS)N)rrrr)rrrrrr __setitem__s   z_Environ.__setitem__cCsD||}||y |j|=Wntk r>t|dYnXdS)N)rrrr)rr encodedkeyrrr __delitem__s    z_Environ.__delitem__ccs(t|j}x|D]}||VqWdS)N)rrr)rkeysrrrr__iter__s  z_Environ.__iter__cCs t|jS)N)lenr)rrrr__len__sz_Environ.__len__cs$ddfddjDS)Nzenviron({{{}}})z, c3s*|]"\}}d||VqdS)z {!r}: {!r}N)formatrr)rrr)rrr sz$_Environ.__repr__..)rrdritems)rr)rr__repr__s z_Environ.__repr__cCst|S)N)dict)rrrrcopysz _Environ.copycCs||kr|||<||S)Nr)rrrrrr setdefaultsz_Environ.setdefaultN) __name__ __module__ __qualname__rrrrrrrrrrrrrrs  rcCsdS)Nr)rrrrrrrcCs t|dS)N)_putenv)rrrrrrrcstdkrLdd}|t}fdd}i}xJtD]\}}||||<q2Wn(tfddfdd }}t}t||||ttS) Nr)cSs t|tstdt|j|S)Nzstr expected, not %s)rQr-rtyper)rrrr check_strs z!_createenviron..check_strcs |S)N)upper)r)encoderrrsz!_createenviron..encodekeycs(t|tstdt|j|dS)Nzstr expected, not %ssurrogateescape)rQr-rrrr)r)encodingrrrs z_createenviron..encodecs |dS)Nr)decode)r)rrrrsz_createenviron..decode) r r-rrsysgetfilesystemencodingrr _unsetenv)rrrrrrr)rrr_createenvirons"   rcCs t||S)zGet an environment variable, return None if it doesn't exist.
