bytes: Immutable Binary Sequences The bytes type in Python represents an immutable sequence of bytes—integers in the range 0 <= x < 256. Its immutability means that once a bytes object is created, its contents cannot be altered. This design choice provides significant benefits, including thread safety, hashability (allowing use as dictionary keys or set elements), and performance optimizations, as the interpreter can rely on the data never changing. It is the go-to type for handling raw binary data from files, network connections, or hardware interfaces where the integrity of the data must be preserved.
