I would like to concatenate a bytearray to another bytearray. I thought this might work:
byt1 = bytearray(10) byt2 = bytearray(10) byt1.join(byt2) print(repr(byt1)) byt1.join(byt2)
TypeError: sequence item 0: expected a bytes-like object, int found
What is the most efficient way to achieve this?

To join a list of Bytes, call the Byte. join(list) method. If you try to join a list of Bytes on a string delimiter, Python will throw a TypeError , so make sure to call it on a Byte object b' '.
To concatenate multiple byte arrays, you can use the Bytes. concat() method, which can take any number of arrays.
Python | bytearray() function bytearray() method returns a bytearray object which is an array of given bytes. It gives a mutable sequence of integers in the range 0 <= x < 256. Returns: Returns an array of bytes of the given size. source parameter can be used to initialize the array in few different ways.
Python program that uses plus on bytearrays left = bytearray (b"hello ") right = bytearray (b"world") # Combine two bytearray objects with plus. both = left + right print (both) Output bytearray (b'hello world')
Python supports another binary sequence type called the bytearray. bytearray objects are very much like bytes objects, despite a couple of differences. 00:15 There isn’t any dedicated syntax for defining a bytearray literal. You can’t use the letter b in the front of a string in the same way that you could with the bytes objects.
We can convert a list of integers to bytearray using bytearray () function in python. The bytearray () function takes the list of integers between 0 and 255 as input and returns the corresponding bytearray object as follows. For integer values which are not between 0 to 255, the bytearray function raises ValueError as follows.
These Python 3 examples use the bytes, bytearray and memoryview built-in types. These types represent binary data in an efficient way. Bytes, bytearray. These objects store binary buffers. With them, we efficiently represent bytes (numbers 0 through 255). Programs often process many bytes.
Create a new combined bytearray from two:
byt_combined = byt1 + byt2 Extend one bytearray with another. This changes byt1:
byt1.extend(byt2) You can join a byte to an array like below:
b"".join([bytearray(10), bytearray(10)]) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
