aifc.getcomptype() Return a bytes array of length 4 describing the type of compression used in the audio file. For AIFF files, the returned value is b'NONE'.

aifc.getcompname() Return a bytes array convertible to a human-readable description of the type of compression used in the audio file. For AIFF files, the returned value is b'not compressed'.

aifc.close() Close the AIFF file. After calling this method, the object can no longer be used.

aifc.aiff() Create an AIFF file. The default is that an AIFF-C file is created, unless the name of the file ends in '.aiff' in which case the default is an AIFF file.

aifc.aifc() Create an AIFF-C file. The default is that an AIFF-C file is created, unless the name of the file ends in '.aiff' in which case the default is an AIFF file.

abs(x) Return the absolute value of a number. The argument may be an integer or a floating point number. If the argument is a complex number, its magnitude is returned.

abc.get_cache_token() Returns the current abstract base class cache token. The token is an opaque object (that supports equality testing) identifying the current version of the abstract base class cache for virtual subclasses. The token changes with every call to ABCMeta.register() on any ABC. New in version 3.4.

@abc.abstractstaticmethod A subclass of the built-in staticmethod(), indicating an abstract staticmethod. Otherwise it is similar to abstractmethod(). This special case is deprecated, as the staticmethod() decorator is now correctly identified as abstract when applied to an abstract method: class C(metaclass=ABCMeta): @staticmethod @abstractmethod def my_abstract_staticmethod(...): ... New in version 3.2. Deprecated since version 3.3: It is now possible to use staticm

@abc.abstractproperty(fget=None, fset=None, fdel=None, doc=None) A subclass of the built-in property(), indicating an abstract property. Using this function requires that the class’s metaclass is ABCMeta or is derived from it. A class that has a metaclass derived from ABCMeta cannot be instantiated unless all of its abstract methods and properties are overridden. The abstract properties can be called using any of the normal ‘super’ call mechanisms. This special case is deprecated, as the pro

@abc.abstractmethod A decorator indicating abstract methods. Using this decorator requires that the class’s metaclass is ABCMeta or is derived from it. A class that has a metaclass derived from ABCMeta cannot be instantiated unless all of its abstract methods and properties are overridden. The abstract methods can be called using any of the normal ‘super’ call mechanisms. abstractmethod() may be used to declare abstract methods for properties and descriptors.
