...os.path stores the module os locally as os, so that the imported submodule path is accessible as os.path. As a result, import os.path as p stores os.path, not os, in p. This makes it effectively the same as from os import path as p Implementation details This PEP has been accepted, and the suggested code change has been checked in. The patch can still be found in the SourceForge patch manager [1]. Currently, a NAME field is used in the grammar rather than a bare string, to avoid the k...
...os.PathLike. os.path The various path-manipulation functions of os.path [9] will be updated to accept path objects. For polymorphic functions that accept both bytes and strings, they will be updated to simply use os.fspath(). During the discussions leading up to this PEP it was suggested that os.path not be updated using an "explicit is better than implicit" argument. The thinking was that since __fspath__() is polymorphic itself it may be better to have code working with os.path extract the p...

...os.path is reused. Many os.path functions are tied by backwards compatibility to confusing or plain wrong behaviour (for example, the fact that os.path.abspath() simplifies ".." path components without resolving symlinks first). Comparisons Paths of the same flavour are comparable and orderable, whether pure or not: >>> PurePosixPath('a') == PurePosixPath('b') False >>> PurePosixPath('a') < PurePosixPath('b') True >>> PurePosixPath('a') == PosixPath('a') True C...
...os.path'. The callable are stored in the dict sys.post_import_hooks which is a mapping from names (as string) to a list of callables or None. States No hook was registered sys.post_import_hooks contains no entry for the module A hook is registered and the module is not loaded yet The import hook registry contains an entry sys.post_import_hooks["name"] = [hook1] A module is successfully loaded The import machinery checks if sys.post_import_hooks contains post import hooks for the newly load...
...os.path: (Windows, DOS:) Treat trailing colon correctly in os.path.join. os.path.join("a:", "b") yields "a:b". pickle: Now raises ValueError when an invalid pickle that contains a non-string repr where a string repr was expected. This behavior matches cPickle. posixfile: Remove broken __del__() method. py_compile: support CR+LF line terminators in source file. readline: Does not immediately exit when ^C is hit when readline and threads are configured. Adds definition o...
...os.path module) when assuming an ASCII-compatible encoding. Using utf-16-le as the encoding is more pure, but will cause more issues than are resolved. This change would also undeprecate the use of bytes paths on Windows. No change to the semantics of using bytes as a path is required - as before, they must be encoded with the encoding specified by sys.getfilesystemencoding(). Specific Changes Update sys.getfilesystemencoding Remove the default value for Py_FileSystemDefaultEncoding and set i...
...os.path.* functions, for example: d = os.path.dirname(__file__) data = __loader__.get_data(os.path.join(d, "logo.gif")) The following set of methods may be implemented if support for (for example) Freeze-like tools is desirable. It consists of three additional methods which, to make it easier for the caller, each of which should be implemented, or none at all: loader.is_package(fullname) loader.get_code(fullname) loader.get_source(fullname) All three methods should raise ImportError if the ...

...os.path.walk(). See os module docs for details. os.path.walk() isn't deprecated at this time, but may become deprecated in a future release. Added new module "platform" which provides a wide range of tools for querying platform dependent features. netrc now allows ASCII punctuation characters in passwords. shelve now supports the optional writeback argument, and exposes pickle protocol versions. Several methods of nntplib.NNTP have grown an optional file argument which specifies a fi...
...os.path or a package's __init__ module that exposes functionality from submodules. Programming Recommendations Code should be written in a way that does not disadvantage other implementations of Python (PyPy, Jython, IronPython, Cython, Psyco, and such). For example, do not rely on CPython's efficient implementation of in-place string concatenation for statements in the form a += b or a = a + b. This optimization is fragile even in CPython (it only works for some types) and isn't present at...
...os.path.lexists(), which returns True for broken symlinks, unlike os.path.exists(). the random module now uses os.urandom() for seeding if it is available. Added a new generator based on os.urandom(). difflib and diff.py can now generate HTML. bdist_rpm now includes version and release in the BuildRoot, and replaces - by _ in version and release. distutils build/build_scripts now has an -e option to specify the path to the Python interpreter for installed scripts.
