What is the method for concatenating bytes in Python?

In Python, we can use the + operator to concatenate bytes objects. It is important to note that bytes objects are immutable, so each concatenation operation will create a new bytes object. Here is an example:

bytes1 = b'Hello'
bytes2 = b'World'
result = bytes1 + bytes2
print(result)  # 输出: b'HelloWorld'

Additionally, multiple bytes objects can also be concatenated using the join() method in Python. Here’s an example:

bytes_list = [b'Hello', b'World']
result = b''.join(bytes_list)
print(result)  # 输出: b'HelloWorld'
