| 8 | |
| 9 | This module implements some useful functions on pathnames. To read or |
| 10 | write files see :func:`open`, and for accessing the filesystem see the |
Martin v. Löwis | 651423c | 2008-10-07 07:03:04 +0000 | [diff] [blame] | 11 | :mod:`os` module. The path parameters can be passed as either strings, |
| 12 | or bytes. Applications are encouraged to represent file names as |
| 13 | (Unicode) character strings. Unfortunately, some file names may not be |
| 14 | representable as strings on Unix, so applications that need to support |
| 15 | arbitrary file names on Unix should use bytes objects to represent |
| 16 | path names. Vice versa, using bytes objects cannot represent all file |
| 17 | names on Windows (in the standard ``mbcs`` encoding), hence Windows |
| 18 | applications should use string objects to access all files. |

R David Murray | a4e700c | 2013-01-06 16:13:10 -0500 | [diff] [blame] | 20 | Unlike a unix shell, Python does not do any *automatic* path expansions. |
| 21 | Functions such as :func:`expanduser` and :func:`expandvars` can be invoked |
| 22 | explicitly when an application desires shell-like path expansion. (See also |
| 23 | the :mod:`glob` module.) |

| 31 | |
| 32 | All of these functions accept either only bytes or only string objects as |
| 33 | their parameters. The result is an object of the same type, if a path or |
| 34 | file name is returned. |

| 38 | |
| 39 | Since different operating systems have different path name conventions, there |
| 40 | are several versions of this module in the standard library. The |
| 41 | :mod:`os.path` module is always the path module suitable for the operating |
| 42 | system Python is running on, and therefore usable for local paths. However, |
| 43 | you can also import and use the individual modules if you want to manipulate |
| 44 | a path that is *always* in one of the different formats. They all have the |
| 45 | same interface: |
| 46 | |
| 47 | * :mod:`posixpath` for UNIX-style paths |
| 48 | * :mod:`ntpath` for Windows paths |
| 49 | * :mod:`macpath` for old-style MacOS paths |

| 53 | |
| 54 | Return a normalized absolutized version of the pathname *path*. On most |
Chris Jerdonek | 0b502ff | 2012-11-25 20:38:01 -0800 | [diff] [blame] | 55 | platforms, this is equivalent to calling the function :func:`normpath` as |
| 56 | follows: ``normpath(join(os.getcwd(), path))``. |

| 59 | .. function:: basename(path) |
| 60 | |
Chris Jerdonek | 0b502ff | 2012-11-25 20:38:01 -0800 | [diff] [blame] | 61 | Return the base name of pathname *path*. This is the second element of the |
| 62 | pair returned by passing *path* to the function :func:`split`. Note that |
| 63 | the result of this function is different |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 64 | from the Unix :program:`basename` program; where :program:`basename` for |
| 65 | ``'/foo/bar/'`` returns ``'bar'``, the :func:`basename` function returns an |
| 66 | empty string (``''``). |
| 67 | |
| 68 | |
| 69 | .. function:: commonprefix(list) |
| 70 | |
| 71 | Return the longest path prefix (taken character-by-character) that is a prefix |
| 72 | of all paths in *list*. If *list* is empty, return the empty string (``''``). |
| 73 | Note that this may return invalid paths because it works a character at a time. |
| 74 | |
| 75 | |
| 76 | .. function:: dirname(path) |
| 77 | |
Chris Jerdonek | 0b502ff | 2012-11-25 20:38:01 -0800 | [diff] [blame] | 78 | Return the directory name of pathname *path*. This is the first element of |
| 79 | the pair returned by passing *path* to the function :func:`split`. |

| 82 | .. function:: exists(path) |
| 83 | |
Richard Oudkerk | 2240ac1 | 2012-07-06 12:05:32 +0100 | [diff] [blame] | 84 | Return ``True`` if *path* refers to an existing path or an open |
| 85 | file descriptor. Returns ``False`` for broken symbolic links. On |
| 86 | some platforms, this function may return ``False`` if permission is |
| 87 | not granted to execute :func:`os.stat` on the requested file, even |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 88 | if the *path* physically exists. |
| 89 | |
Richard Oudkerk | 2240ac1 | 2012-07-06 12:05:32 +0100 | [diff] [blame] | 90 | .. versionchanged:: 3.3 |
| 91 | *path* can now be an integer: ``True`` is returned if it is an |
| 92 | open file descriptor, ``False`` otherwise. |

| 95 | .. function:: lexists(path) |
| 96 | |
| 97 | Return ``True`` if *path* refers to an existing path. Returns ``True`` for |
| 98 | broken symbolic links. Equivalent to :func:`exists` on platforms lacking |
| 99 | :func:`os.lstat`. |
| 100 | |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 101 | |
| 102 | .. function:: expanduser(path) |
| 103 | |
| 104 | On Unix and Windows, return the argument with an initial component of ``~`` or |
| 105 | ``~user`` replaced by that *user*'s home directory. |
| 106 | |
| 107 | .. index:: module: pwd |
| 108 | |
| 109 | On Unix, an initial ``~`` is replaced by the environment variable :envvar:`HOME` |
| 110 | if it is set; otherwise the current user's home directory is looked up in the |
| 111 | password directory through the built-in module :mod:`pwd`. An initial ``~user`` |
| 112 | is looked up directly in the password directory. |
| 113 | |
| 114 | On Windows, :envvar:`HOME` and :envvar:`USERPROFILE` will be used if set, |
| 115 | otherwise a combination of :envvar:`HOMEPATH` and :envvar:`HOMEDRIVE` will be |
| 116 | used. An initial ``~user`` is handled by stripping the last directory component |
| 117 | from the created user path derived above. |
| 118 | |
| 119 | If the expansion fails or if the path does not begin with a tilde, the path is |
| 120 | returned unchanged. |
| 121 | |
| 122 | |
| 123 | .. function:: expandvars(path) |
| 124 | |
| 125 | Return the argument with environment variables expanded. Substrings of the form |
| 126 | ``$name`` or ``${name}`` are replaced by the value of environment variable |
| 127 | *name*. Malformed variable names and references to non-existing variables are |
| 128 | left unchanged. |
| 129 | |
| 130 | On Windows, ``%name%`` expansions are supported in addition to ``$name`` and |
| 131 | ``${name}``. |
| 132 | |
| 133 | |
| 134 | .. function:: getatime(path) |
| 135 | |
| 136 | Return the time of last access of *path*. The return value is a number giving |
| 137 | the number of seconds since the epoch (see the :mod:`time` module). Raise |
Andrew Svetlov | 618c2e1 | 2012-12-15 22:59:24 +0200 | [diff] [blame] | 138 | :exc:`OSError` if the file does not exist or is inaccessible. |

| 170 | |
Christian Heimes | af98da1 | 2008-01-27 15:18:18 +0000 | [diff] [blame] | 171 | Return ``True`` if *path* is an absolute pathname. On Unix, that means it |
| 172 | begins with a slash, on Windows that it begins with a (back)slash after chopping |
| 173 | off a potential drive letter. |
Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 174 | |

| 176 | .. function:: isfile(path) |
| 177 | |
| 178 | Return ``True`` if *path* is an existing regular file. This follows symbolic |
| 179 | links, so both :func:`islink` and :func:`isfile` can be true for the same path. |
| 180 | |
| 181 | |
| 182 | .. function:: isdir(path) |
| 183 | |
| 184 | Return ``True`` if *path* is an existing directory. This follows symbolic |
| 185 | links, so both :func:`islink` and :func:`isdir` can be true for the same path. |
| 186 | |
| 187 | |
| 188 | .. function:: islink(path) |
| 189 | |
| 190 | Return ``True`` if *path* refers to a directory entry that is a symbolic link. |
Benjamin Peterson | f6f78e1 | 2014-06-22 17:59:35 -0700 | [diff] [blame] | 191 | Always ``False`` if symbolic links are not supported by the python runtime. |

| 195 | |
Larry Hastings | 3732ed2 | 2014-03-15 21:13:56 -0700 | [diff] [blame] | 196 | Return ``True`` if pathname *path* is a :dfn:`mount point`: a point in a |
| 197 | file system where a different file system has been mounted. On POSIX, the |
| 198 | function checks whether *path*'s parent, :file:`path/..`, is on a different |
| 199 | device than *path*, or whether :file:`path/..` and *path* point to the same |
| 200 | i-node on the same device --- this should detect mount points for all Unix |
| 201 | and POSIX variants. On Windows, a drive letter root and a share UNC are |
| 202 | always mount points, and for any other path ``GetVolumePathName`` is called |
| 203 | to see if it is different from the input path. |
| 204 | |
| 205 | .. versionadded:: 3.4 |
| 206 | Support for detecting non-root mount points on Windows. |

Georg Brandl | 116aa62 | 2007-08-15 14:28:22 +0000 | [diff] [blame] | 210 | |
Zachary Ware | a13dab4 | 2014-10-10 16:03:14 -0500 | [diff] [blame^] | 211 | Join one or more path components intelligently. The return value is the |
| 212 | concatenation of *path* and any members of *\*paths* with exactly one |
| 213 | directory separator (``os.sep``) following each non-empty part except the |
| 214 | last, meaning that the result will only end in a separator if the last |
| 215 | part is empty. If a component is an absolute path, all previous |
| 216 | components are thrown away and joining continues from the absolute path |
| 217 | component. |
| 218 | |
| 219 | On Windows, the drive letter is not reset when an absolute path component |
| 220 | (e.g., ``r'\foo'``) is encountered. If a component contains a drive |
| 221 | letter, all previous components are thrown away and the drive letter is |
| 222 | reset. Note that since there is a current directory for each drive, |
| 223 | ``os.path.join("c:", "foo")`` represents a path relative to the current |
| 224 | directory on drive :file:`C:` (:file:`c:foo`), not :file:`c:\\foo`. |

| 240 | that contains symbolic links. On Windows, it converts forward slashes to |
Terry Jan Reedy | f346041 | 2013-03-17 15:28:10 -0400 | [diff] [blame] | 241 | backward slashes. To normalize case, use :func:`normcase`. |

| 303 | last pathname component and *head* is everything leading up to that. The |
| 304 | *tail* part will never contain a slash; if *path* ends in a slash, *tail* |
| 305 | will be empty. If there is no slash in *path*, *head* will be empty. If |
| 306 | *path* is empty, both *head* and *tail* are empty. Trailing slashes are |
| 307 | stripped from *head* unless it is the root (one or more slashes only). In |
| 308 | all cases, ``join(head, tail)`` returns a path to the same location as *path* |

| 326 | If the path contains a UNC path, drive will contain the host name |
| 327 | and share, up to but not including the fourth separator. |
