What is the purpose of 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' Python byte() function converts an object to an immutable byte-represented object of given size and data.
Python bytes() exampleExample 1: Convert string to bytesIn this example, we are going to convert string to bytes using the Python bytes() function, for this we take a variable with string and pass it into the bytes() function with UTF-8 parameters. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte code units Python3
Output: b'Welcome to Geeksforgeeks' Example 2: Array of bytes from an integerIn this example, we are going to see how to get an array of bytes from an integer using the Python bytes() function, for this we will pass the integer into the bytes() function. Python3
Output: b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' Example 3: Null parameters with bytes()When we pass nothing in bytes() function then it creates an array of size 0. Python3Output: b'' Example 4: Demonstrating byte() on integers, none and iterablesPython3
Output: Byte conversion with no arguments : b'' The integer conversion results in : b'\x00\x00\x00\x00' The iterable conversion results in : b'\x01\x02\x03\x04\x05' Behavior of Bytes with StringsBytes accept a string as an argument and require an encoding scheme with it to perform it. The most important aspect of this is handling errors in case of encoding failure, some of the error handling schemes defined are :
Example: Demonstration of bytes() using stringPython3
Output: Byte conversion with ignore error : b'GeeksfrGeeks' Byte conversion with replace error : b'Geeksf?rGeeks' Exception :
What is bytes type in Python?In short, the bytes type is a sequence of bytes that have been encoded and are ready to be stored in memory/disk. There are many types of encodings (utf-8, utf-16, windows-1255), which all handle the bytes differently. The bytes object can be decoded into a str type. The str type is a sequence of unicode characters.
What is '\ x00 in Python?The \x00 character is a Null-character that represents a HEX byte with all bits at 0. The first example uses the str. replace() method to replace all occurrences of the character with an empty string.
How do you declare bytes in Python?string = "Python is interesting." # string with encoding 'utf-8' arr = bytes(string, 'utf-8') print(arr) Run Code.. size = 5. arr = bytes(size) print(arr) Run Code.. rList = [1, 2, 3, 4, 5] arr = bytes(rList) print(arr) Run Code.. |
