The surprising way to save memory with BytesIO

Read Original

This Python tutorial explains the memory overhead of using BytesIO.read() and demonstrates two efficient alternatives: getbuffer() which returns a memoryview without copying data, and getvalue() which returns bytes but can be more memory-efficient in some cases. The article includes code examples and memory measurements to help developers optimize in-memory byte handling.
