# Python File writelines() Method

## Description:

This method writes a sequence of strings to the file. The sequence can be any iterable object producing strings, typically a list of strings. There is no return value.

## Syntax:

    fileObject.writelines( sequence )

## Parameters:

Here is the detail of parameters:

- sequence: Sequence of the strings.

## Example:

    #!/usr/bin/python

    # Open a file
    fo = open("foo.txt", "rw+")
    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

    seq = ["This is 6th line\n", "This is 7th line"]
    # Write sequence of lines at the end of the file.
    fo.seek(0, 2)
    line = fo.writelines( seq )

    # Now read complete file from beginning.
    fo.seek(0,0)
    for index in range(7):
       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

    Line No 5 - This is 6th line

    Line No 6 - This is 7th line
