Bytearrays
Bytearrays are mutable sequences of bytes used to store binary data. Each element is an integer in the range 0 to 255, and the container provides a contiguous memory buffer suitable for low-level data manipulation. In Python and many other environments, a bytearray is a dedicated type that supports in-place modification.
Creation and mutation: A bytearray can be created from an iterable of integers, from an existing bytes
Common operations and conversions: Bytearrays support slicing, length queries, and iteration. They can be converted to
Interoperability and memory considerations: Bytearrays expose the underlying buffer for zero-copy access via views like memoryview,
Context and use cases: Across programming languages, byte arrays serve a similar role—buffering file and network
