- Write a Python function that writes multiple lines to a buffer, prints the buffer's content, and then discards it by closing the buffer.
- Write a Python script to simulate file operations on a memory buffer: write data, read it back, and then reset the buffer to an empty state.
- Write a Python program to use an in-memory buffer to temporarily store text, print the content, and then demonstrate that the buffer is empty after discarding.
