Instances are callable if their class has a _call_() method.Ĭhanged in version 3.11: Class methods can no longer wrap other descriptors such as Note that classes are callable (calling a class returns a new instance) If this returns True, it is still possible that aĬall fails, but if it is False, calling object will never succeed. Return True if the object argument appears callable,įalse if not. See also Binary Sequence Types - bytes, bytearray, memoryview, Bytes Objects, and Bytes and Bytearray Operations.
bytes is an immutable version ofīytearray – it has the same non-mutating methods and the sameĪccordingly, constructor arguments are interpreted as for bytearray().īytes objects can also be created with literals, see String and Bytes literals. Return a new “bytes” object which is an immutable sequence of integers in class bytes ( source = b'' ) class bytes ( source, encoding ) class bytes ( source, encoding, errors ) See also Binary Sequence Types - bytes, bytearray, memoryview and Bytearray Objects. Without an argument, an array of size 0 is created. If it is an iterable, it must be an iterable of integers in the rangeĠ <= x < 256, which are used as the initial contents of the array. If it is an object conforming to the buffer interface,Ī read-only buffer of the object will be used to initialize the bytes array. If it is an integer, the array will have that size and will be
If it is a string, you must also give the encoding (and optionally,Įrrors) parameters bytearray() then converts the string to The optional source parameter can be used to initialize the array in a few Methods of mutable sequences, described in Mutable Sequence Types, as wellĪs most methods that the bytes type has, see Bytes and Bytearray Operations. Sequence of integers in the range 0 <= x < 256. class bytearray ( source = b'' ) class bytearray ( source, encoding ) class bytearray ( source, encoding, errors )
