![]() This method does the exact same thing as the decode() method in the previous example.įor instance: byte_string = b"Do you want a slice of \xf0\x9f\x8d\x95?" The str() FunctionĪnother approach to convert bytes to string is by using the built-in str() function. You can also pass the encoding type to this function as an argument.įor example, let’s use the UTF-8 encoding for converting bytes to a string: byte_string = b"Do you want a slice of \xf0\x9f\x8d\x95?" Given a bytes object, you can use the built-in decode() method to convert the byte to a string. Now, let’s see how to convert between bytes and string. If there was no special string representation for a bytes object, printing bytes would be nonsense.Īnyway, now you understand what is a bytes object in Python, and how it differs from the str object. Python does this for the developer’s convenience. The reason why the byte string prints out as a readable string is because what you see is actually a string representation of the bytes object. To make one more thing clear, let’s see what happens if we print the bytes object name2 as-is: name1 = 'Alice'Īs your surprize, it clearly says “Alice”. Something that a computer can understand. ![]() Those numbers are the byte values of the characters in a string. Here you can see there is no way for you to tell what those numbers mean. Now, let’s print each byte in the name2 bytes object: name1 = 'Alice' To see the main difference between the byte string and a string, let’s print the words character by character.įirst, let’s do the name1 variable: name1 = 'Alice' In the above code, this isn’t clear as you can just read the b’Alice’ very clearly. You can verify this by printing out the data types of these variables: name1 = 'Alice'Īs I mentioned earlier, the byte string is something that is hard to understand. ![]() A bytes object is prefixed with the letter ‘ b‘.įor example, take a look at these two variables: name1 = 'Alice' In Python, a bytes object is a byte representation of a string. This is why any string needs to be converted to a byte string before the computer can use it. In Python, a byte string is a sequence of bytes that the computer understands but humans can’t.Ī string is a sequence of characters and is something we humans can understand but cannot directly store in a computer. But this might vary depending on what system you’re using. Storing data to a computer happens by using groups of bits, also known as bytes. This is because computers operate on bits, that is, 0s and 1s. Why Bytes?Ī computer doesn’t understand the notion of “text” or “number” as is. Before jumping into the conversions, let’s take a quick look at what are bytes in the first place. There is a chance you are looking to convert bytes to strings because you do not know what they are. We can convert bytes into hex strings using the codecs.encode() function.Let’s jump to it! Bytes vs Strings in Python This module contains numerous functions such as codecs.encode() and code(), codecs.lookup(), etc. ![]() It also defines base classes for specific text to text, or text to bytes encoding and decoding. The codecs module, in simple words, is used to encode text to bytes or any other formats as specified. Method 1: Encoding Bytes to Hex Strings using Codecs Module Let’s dive into the four methods for converting bytes to hex strings in Python. Each method is efficient and easy to implement, providing a flexible approach to byte-to-hex conversions. You can use Python’s built-in modules like codecs, binascii, and struct or directly leverage the bytes.hex() function. In Python 3, there are several ways to convert bytes to hex strings. And just like every other in built solution that Python provides, in this article, we will look at four very simple built in methods that will help us convert a byte into a hex string. In Python, a bit is represented by adding a lowercase ‘b’ prefix to a string.Ī hex string, or a hexadecimal string, combines digits from 0 to 9 and letters from A to F to represent numbers in base 16, a number system widely used in computing. Bytes are eight bits long, they might represent numbers, digits, strings and letters. This binary representation serves as the building block of computer memory. In computer programming, a byte, consisting of eight bits, is a fundamental unit of data storage.
