# Python File next() Method

## Description:

This method is used when a file is used as an iterator, typically in a loop, the next() method is called repeatedly. This method returns the next input line, or raises StopIteration when EOF is hit.

Combining next() method with other file methods like readline() does not work right. However, using seek() to reposition the file to an absolute position will flush the read-ahead buffer.

## Syntax:

    fileObject.next();

## Parameters:

Here is the detail of parameters:

- NA

## Example:

    #!/usr/bin/python

    # Open a file
    fo = open("foo.txt", "r")
    print "Name of the file: ", fo.name

    # Assuming file has following 5 lines
    # This is 1st line
    # This is 2nd line
    # This is 3rd line
    # This is 4th line
    # This is 5th line

    for index in range(5):
       line = fo.next()
       print "Line No %d - %s" % (index, line)

    # Close opend file
    fo.close()

This produces following result:

    Name of the file:  foo.txt
    Line No 0 - This is 1st line
    Line No 1 - This is 2nd line
    Line No 2 - This is 3rd line
    Line No 3 - This is 4th line
    Line No 4 - This is 5th line
