Python bytes() Function
<div><p class="has-pale-cyan-blue-background-color has-background">Python’s built-in <code>bytes(source)</code> function creates an immutable <code>bytes</code> object initialized as defined in the function argument <code>source</code>. A bytes object is like a string but it uses only byte characters consisting of a sequence of 8-bit integers in the range <code>0<=x<256</code>. The returned byte object is immutable—you cannot change it after creation. If you plan to change the contents, use the <code><a href="https://blog.finxter.com/python-bytearray-function/" title="Python bytearray() Function" target="_blank" rel="noreferrer noopener">bytearray()</a></code> method to create a mutable <code>bytearray</code> object. </p>

<p>Here’s a minimal example that creates a <code>byte</code> from three integers stored in a list:</p>

<h2>Create Bytes Object From Single Integer Argument — Examples </h2>
<p>The following code shows you how to use the <code>bytes()</code> function on simple integer arguments.</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group=""># Single Integer Input Argument
print(bytes())
print(bytes(2))
print(bytes(4)) '''
b''
b'\x00\x00'
b'\x00\x00\x00\x00' '''</pre>
<p>If you provide only one input argument, it uses this input argument to determine how many bytes should be created. It just uses bytes with value 0, in byte notation <code>x00</code> to fill the <code>byte</code>.</p>
<h2>Create Bytes Object From Iterable of Integers — Examples</h2>
<p>You can also provide an iterable argument to obtain a new byte object:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group=""># Iterable Input Argument
print(bytes([1, 1, 1]))
print(bytes([14]))
print(bytes({9, 8, 7})) '''
b'\x01\x01\x01'
b'\x0e'
b'\x08\t\x07' '''
</pre>
<p>The iterable must consist of a number of integers between 0 and 256. If you fail to do so, Python will throw a ValueError:</p>
<h2>How to Fix “ValueError: byte must be in range(0, 256)”</h2>
<p class="has-pale-cyan-blue-background-color has-background">If you use the <code>bytes()</code> function on an iterable that contains at least one integer greater than the maximum number representable by 8 bits, namely 256, or smaller than 0, Python will throw a <code>ValueError: byte must be in range(0, 256)</code>. You can fix it by ensuring that each number in your iterable can actually be represented by 8 bits and falls into the interval 0 to 256. </p>
<p>Here’s an example of the ValueError where you use a number larger or equal than 256:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">>>> bytes([999])
Traceback (most recent call last): File "<pyshell#15>", line 1, in <module> bytes([999])
ValueError: bytes must be in range(0, 256)</pre>
<p>Another example when using a number smaller than 0:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">>>> bytes([-10])
Traceback (most recent call last): File "<pyshell#16>", line 1, in <module> bytes([-10])
ValueError: bytes must be in range(0, 256)</pre>
<p>Fix it by modifying the numbers to lie within the interval 0 to 256:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">>>> bytes([255])
