Tab Delimiter to csv in python:perl

Hi
How do we handle delimiter values in python or perl to convert the field values from 3 columns to 2 columns into csv file

Columns Values

Product : Contain one value
ID : Ignore this
Features : Contains multiple values separated by tab

$cat Check_File
Code:
Product                ID                   Features 
Apple-for-Laptop 1.2.13.22 itunes app-stores health    # [ Product1 ]
Samsung-for-Mobile 5.43.67  music play-store long-battery    # [ Product2 ]
Nokia 4.1.2 long-battery    # [ Product3 ]


Expected format :
Code:
Product, Features
Apple-for-Laptop,itunes
Apple-for-Laptop,app-stores
Apple-for-Laptop,health   
Samsung-for-Mobile,music 
Samsung-for-Mobile,play-store 
Samsung-for-Mobile,long-battery 
Nokia,long-battery

Is there better way to handle this in python/perl . The file is big with 200 Million records.

NAME
Plack::Session::Store::File - Basic file-based session store SYNOPSIS
use Plack::Builder; use Plack::Middleware::Session; use Plack::Session::Store::File; my $app = sub { return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ]; }; builder { enable 'Session', store => Plack::Session::Store::File->new( dir => '/path/to/sessions' ); $app; }; # with custom serializer/deserializer builder { enable 'Session', store => Plack::Session::Store::File->new( dir => '/path/to/sessions', # YAML takes it's args the opposite order serializer => sub { YAML::DumpFile( reverse @_ ) }, deserializer => sub { YAML::LoadFile( @_ ) }, ); $app; }; DESCRIPTION
This implements a basic file based storage for session data. By default it will use Storable to serialize and deserialize the data, but this can be configured easily. This is a subclass of Plack::Session::Store and implements its full interface. METHODS
new ( %params ) The %params can include dir, serializer and deserializer options. It will check to be sure that the dir is writable for you. dir This is the directory to store the session data files in, if nothing is provided then "/tmp" is used. serializer This is a CODE reference that implements the serialization logic. The CODE ref gets two arguments, the $value, which is a HASH reference to be serialized, and the $file_path to save it to. It is not expected to return anything. deserializer This is a CODE reference that implements the deserialization logic. The CODE ref gets one argument, the $file_path to load the data from. It is expected to return a HASH reference. BUGS
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT. AUTHOR
