class http.cookiejar.FileCookieJar(filename, delayload=None, policy=None) policy is an object implementing the CookiePolicy interface. For the other arguments, see the documentation for the corresponding attributes. A CookieJar which can load cookies from, and perhaps save cookies to, a file on disk. Cookies are NOT loaded from the named file until either the load() or revert() method is called. Subclasses of this class are documented in section FileCookieJar subclasses and co-operation with

class mmap.mmap(fileno, length, tagname=None, access=ACCESS_DEFAULT[, offset]) (Windows version) Maps length bytes from the file specified by the file handle fileno, and creates a mmap object. If length is larger than the current size of the file, the file is extended to contain length bytes. If length is 0, the maximum length of the map is the current size of the file, except that if the file is empty Windows raises an exception (you cannot create an empty mapping on Windows). tagname, if s

fcntl.lockf(fd, cmd, len=0, start=0, whence=0) This is essentially a wrapper around the fcntl() locking calls. fd is the file descriptor of the file to lock or unlock, and cmd is one of the following values: LOCK_UN – unlock LOCK_SH – acquire a shared lock LOCK_EX – acquire an exclusive lock When cmd is LOCK_SH or LOCK_EX, it can also be bitwise ORed with LOCK_NB to avoid blocking on lock acquisition. If LOCK_NB is used and the lock cannot be acquired, an OSError will be raised and the

os.removexattr(path, attribute, *, follow_symlinks=True) Removes the extended filesystem attribute attribute from path. attribute should be bytes or str. If it is a string, it is encoded with the filesystem encoding. This function can support specifying a file descriptor and not following symlinks.

class property(fget=None, fset=None, fdel=None, doc=None) Return a property attribute. fget is a function for getting an attribute value. fset is a function for setting an attribute value. fdel is a function for deleting an attribute value. And doc creates a docstring for the attribute. A typical use is to define a managed attribute x: class C: def __init__(self): self._x = None def getx(self): return self._x def setx(self, value): self._x = value d

class nntplib.NNTP(host, port=119, user=None, password=None, readermode=None, usenetrc=False[, timeout]) Return a new NNTP object, representing a connection to the NNTP server running on host host, listening at port port. An optional timeout can be specified for the socket connection. If the optional user and password are provided, or if suitable credentials are present in /.netrc and the optional flag usenetrc is true, the AUTHINFO USER and AUTHINFO PASS commands are used to identify and au

class email.headerregistry.Address(display_name='', username='', domain='', addr_spec=None) The class used to represent an email address. The general form of an address is: [display_name] <username@domain> or: username@domain where each part must conform to specific syntax rules spelled out in RFC 5322. As a convenience addr_spec can be specified instead of username and domain, in which case username and domain will be parsed from the addr_spec. An addr_spec must be a properly RFC qu

__debug__ This constant is true if Python was not started with an -O option. See also the assert statement.

zip(*iterables) Make an iterator that aggregates elements from each of the iterables. Returns an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. The iterator stops when the shortest input iterable is exhausted. With a single iterable argument, it returns an iterator of 1-tuples. With no arguments, it returns an empty iterator. Equivalent to: def zip(*iterables): # zip('ABCD', 'xy') --> Ax By sentinel = object()

TarInfo.uid User ID of the user who originally stored this member.
