In order to check the actual value of each byte of both bytes objects, we can iterate them with a for in loop and print each element.
#PYTHON HOW TO ENCODE A MESSAGE TO BYTES CODE#
The result for this portion of the code can be seen below at figure 2.įigure 2 – String to bytes, using the string encode method. We will again print the object returned by this method, to confirm that this is also a bytes object. As stated in the introductory section, since this method has UTF-8 as the default encoding when no argument is given, then we will not pass any input to it. Moving on, we will now use the second mentioned procedure of conversion, which is calling the encode method on the string. Note that although printing the object shows a user friendly textual representation, the data contained in it are actually bytes, as we will see below.įigure 1 – String to bytes, using the bytes object constructor.
As can be seen, we obtain an object of class bytes, as expected. We will also print our bytes object, created from the string. To print the type of a variable, we can simply use Python’s type function. We will store the result in a variable and then print its type, so we can confirm that it is indeed a bytes object. As second, we need to specify the encoding, which will be utf-8. To do so, we pass the string as first input of the constructor of the bytes class. Then, using the first approach, we will create a bytes object from the previous string. We will start by declaring a string, which we will use to convert to bytes using the two procedures mentioned on the introductory section. This tutorial was tested on Python version 3.6. You can read more about Python standard encodings here. This method also receives as input the encoding of the text as a string, although in opposition to the previously mentioned constructor this parameter is optional and defaults to UTF-8. Īlternatively, we can obtain an encoded version of a string as a bytes object by calling the encode method.
Additionally, we need to specify the encoding of the text (in string format) as second argument of the constructor. One of the ways of performing this conversion is by using the bytes class constructor, passing as input the string. Bytes objects are immutable sequences of single bytes in the range between o and 255 (inclusive). In this post, we will check how to convert a Python string to a bytes object.
