The flush() file method can be called to force the interpreter to flush the output buffer to disk.

BlackTom AI · Accepted Answer

The statement asserts that the flush() file method can be called to force the interpreter to flush the output buffer to disk.
In many programming environments, a flush() call is used to write any data held in the language's buffered I/O layer out to the operating system, ensuring that data is no longer just sitting in memory.
However, it’s important to clarify that flush() typically pushes data from the language runtime into the OS buffers. Whether that data is physically written to disk immediately depends on the operating system’s buffering and cache policies; a subsequent fsync-equivalent call may be required to guarantee a write to disk itself.
Given these nuances, flush() does perform the act of flushing the language-level buffer, which is often described as pushing data toward disk, but the absolute guarantee of a disk write is contingent on the OS, not just flush().
Option: True. This is because flush() is the standard mechanism to push buffered output toward the OS, aligning with the idea of flushing buffers, even though a later disk write isn’t strictly guaranteed without further actions like fsync.
