How do you access bytes in python?
In this tutorial, we will learn about the Python bytes() method with the help of examples. Show
The Example
bytes() SyntaxThe syntax of bytes([source[, encoding[, errors]]])
If you want to use the mutable version, use the bytearray() method. bytes() Parameters
The source parameter can be used to initialize the byte array in the following ways:
bytes() Return ValueThe Example 1: Convert string to bytes
Output b'Python is interesting.' Example 2: Create a byte of given integer size
Output b'\x00\x00\x00\x00\x00' Example 3: Convert iterable list to bytes
Output b'\x01\x02\x03\x04\x05' Bytes, BytearrayPython supports a range of types to store sequences. There are six sequence types: strings, byte sequences (bytes objects), byte arrays (bytearray objects), lists, tuples, and range objects. Strings contain Unicode characters. Their literals are written in single or double quotes : 'python', "data". Bytes and bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence. Bytes objects can be constructed the constructor, bytes(), and from literals; use a b prefix with normal string syntax: b'python'. To construct byte arrays, use the bytearray() function. Bytes literalsbytesliteral ::= bytesprefix(shortbytes | longbytes) bytesprefix ::= "b" | "B" | "br" | "Br" | "bR" | "BR" shortbytes ::= "'" shortbytesitem* "'" | '"' shortbytesitem* '"' longbytes ::= "'''" longbytesitem* "'''" | '"""' longbytesitem* '"""' shortbytesitem ::= shortbyteschar | bytesescapeseq longbytesitem ::= longbyteschar | bytesescapeseq shortbyteschar ::= bytes() and bytearray() functionsbytes() function: Return a new "bytes" object, which is an immutable sequence of small integers in the range 0 <= x < 256, print as ASCII characters when displayed. bytes is an immutable version of bytearray – it has the same non-mutating methods and the same indexing and slicing behavior. Syntax: bytes([source[, encoding[, errors]]]) bytearray() function : Return a new array of bytes. The bytearray type is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Byte Array Methods. Syntax: bytearray([source[, encoding[, errors]]]) The optional source parameter can be used to initialize the array in a few different ways:
Without an argument, an array of size 0 is created. Create a bytes object in PythonExample-1 : Code :

Previous: Python break, continue Test your Python skills with w3resource's quiz How do you read bytes in Python?Use open() and file.read() to read bytes from binary file. file = open("sample.bin", "rb"). byte = file. read(1). while byte: byte=false at end of file.. print(byte). byte = file. read(1). file. close(). How do you specify bytes in Python?Convert strings to bytes. string = "Hello World". # string with encoding 'utf-8'. arr = bytes(string, 'utf-8'). arr2 = bytes(string, 'ascii'). print(arr,'\n'). What does bytes () do in Python?Python bytes() Function
The bytes() function returns a bytes object. It can convert objects into bytes objects, or create empty bytes object of the specified size.
How does Python store bytes?For Python 2. x, your best bet is to store them in a string. Once you have that string, you can encode it into safe ASCII values using the base64 module that comes with python. This will be much more condensed than storing "1" and "0".
