In Python, and in general - does a close() operation on a file object imply a flush() operation?

flush() writes the content of the buffer to the destination and makes the buffer empty for further data to store but it does not closes the stream permanently. That means you can still write some more data to the stream. But close() closes the stream permanently.
The flush() method in Python file handling clears the internal buffer of the file. In Python, files are automatically flushed while closing them. However, a programmer can flush a file before closing it by using the flush() method.
The close() method of a file object flushes any unwritten information and closes the file object, after which no more writing can be done. Python automatically closes a file when the reference object of a file is reassigned to another file. It is a good practice to use the close() method to close a file.
Description. Python file method flush() flushes the internal buffer, like stdio's fflush. This may be a no-op on some file-like objects. Python automatically flushes the files when closing them.
Yes. It uses the underlying close() function which does that for you (source).
