Request.unverifiable boolean, indicates whether the request is unverifiable as defined by RFC 2965.

Queue.put(item, block=True, timeout=None) Put item into the queue. If optional args block is true and timeout is None (the default), block if necessary until a free slot is available. If timeout is a positive number, it blocks at most timeout seconds and raises the Full exception if no free slot was available within that time. Otherwise (block is false), put an item on the queue if a free slot is immediately available, else raise the Full exception (timeout is ignored in that case).

header_fetch_parse(name, value) If the value has a name attribute, it is returned to unmodified. Otherwise the name, and the value with any CR or LF characters removed, are passed to the header_factory, and the resulting header object is returned. Any surrogateescaped bytes get turned into the unicode unknown-character glyph.

class test.support.EnvironmentVarGuard Class used to temporarily set or unset environment variables. Instances can be used as a context manager and have a complete dictionary interface for querying/modifying the underlying os.environ. After exit from the context manager all changes to environment variables done through this instance will be rolled back. Changed in version 3.1: Added dictionary interface.

class types.SimpleNamespace A simple object subclass that provides attribute access to its namespace, as well as a meaningful repr. Unlike object, with SimpleNamespace you can add and remove attributes. If a SimpleNamespace object is initialized with keyword arguments, those are directly added to the underlying namespace. The type is roughly equivalent to the following code: class SimpleNamespace: def __init__(self, **kwargs): self.__dict__.update(kwargs) def __repr__(self):

exploded The string representation in dotted decimal notation. Leading zeroes are never included in the representation. As IPv4 does not define a shorthand notation for addresses with octets set to zero, these two attributes are always the same as str(addr) for IPv4 addresses. Exposing these attributes makes it easier to write display code that can handle both IPv4 and IPv6 addresses.

OpenerDirector.error(proto, *args) Handle an error of the given protocol. This will call the registered error handlers for the given protocol with the given arguments (which are protocol specific). The HTTP protocol is a special case which uses the HTTP response code to determine the specific error handler; refer to the http_error_*() methods of the handler classes. Return values and exceptions raised are the same as those of urlopen().

ctypes.PYFUNCTYPE(restype, *argtypes) The returned function prototype creates functions that use the Python calling convention. The function will not release the GIL during the call.

is_closing(self) Return True if the transport is closing or is closed. New in version 3.5.1.

ascii(object) As repr(), return a string containing a printable representation of an object, but escape the non-ASCII characters in the string returned by repr() using \x, \u or \U escapes. This generates a string similar to that returned by repr() in Python 2.
