Python File flush() Method
Python File MethodsOverview
flush()The method is used to flush the buffer, that is, to immediately write the data in the buffer to the file and clear the buffer, without passively waiting for the output buffer to be written.
Generally, the buffer is automatically flushed after the file is closed, but sometimes you need to flush it before closing, and you can use the flush() method in this case.
Syntax
The syntax of the flush() method is as follows:
fileObject.flush();
Parameters
None
Return Value
This method has no return value.
Example
The following example demonstrates the use of the flush() method:
Example
#!/usr/bin/python
# -*- coding: UTF-8 -*-
# Open the file
fo = open("example.txt", "wb")
print "The file name is:", fo.name
# Flush the buffer
fo.flush()
# Close the file
fo.close()
The output of the above example is:
文件名为: example.txtOther Extensions
