exception ReferenceError This exception is raised when a weak reference proxy, created by the weakref.proxy() function, is used to access an attribute of the referent after it has been garbage collected. For more information on weak references, see the weakref module.

network The network (IPv4Network) this interface belongs to. >>> interface = IPv4Interface('192.0.2.5/24') >>> interface.network IPv4Network('192.0.2.0/24')

shlex.instream The input stream from which this shlex instance is reading characters.

yeardayscalendar(year, width=3) Return the data for the specified year ready for formatting (similar to yeardatescalendar()). Entries in the week lists are day numbers. Day numbers outside this month are zero.

exception TypeError Raised when an operation or function is applied to an object of inappropriate type. The associated value is a string giving details about the type mismatch.

monthdatescalendar(year, month) Return a list of the weeks in the month month of the year as full weeks. Weeks are lists of seven datetime.date objects.

shlex.split(s, comments=False, posix=True) Split the string s using shell-like syntax. If comments is False (the default), the parsing of comments in the given string will be disabled (setting the commenters attribute of the shlex instance to the empty string). This function operates in POSIX mode by default, but uses non-POSIX mode if the posix argument is false. Note Since the split() function instantiates a shlex instance, passing None for s will read the string to split from standard in

time.perf_counter() Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid. New in version 3.3.

json.load(fp, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, **kw) Deserialize fp (a .read()-supporting file-like object containing a JSON document) to a Python object using this conversion table. object_hook is an optional function that will be called with the result of any object literal decoded (a dict). The return value of object_hook will be used instead of the dict. This feature can be used to implement custom decoders (e.g. J

iterweekdays() Return an iterator for the week day numbers that will be used for one week. The first value from the iterator will be the same as the value of the firstweekday property.
