Python - File flush() Method

The Python flush() method is used to flush out the internal buffer. When a file is closed, Python automatically flushes out the internal buffer. This method is useful when the flushing of the internal buffer is needed while the file is open. Please note that this method may be a no-op on some file-like objects.

Syntax

file.flush()

Parameters

No parameter is required.

Return Value

None.

Example: Flush internal buffer

In the example below, Python file flush() method is used to flush the internal buffer.

MyFile = open("test.txt", "w+")
MyFile.write("This is a demo content.")

#sets the offset position to the beginning
MyFile.seek(0)

#read content before closing the file
print("Name of the file:", MyFile.name)
print(MyFile.read())

#flushing the internal buffer
MyFile.flush()

#closing the open file
MyFile.close()

The output of the above code will be:

Name of the file: test.txt
This is a demo content.
