Oh ok. Well just keep in mind that 4GB of flash memory can be bought in 
China for about 5 euros.

Since programming time is pretty expensive you need to do your sums 
about where you want to spend the time/money.

Python modules are byte compiled. You can usually cut out a lot/some of 
space by removing the source (.py) and leaving the compile (.pyc) modules.

There is usually a lib or a sitelib directory. You could try cleaning 
that out of unwanted modules.

My advice would be to simply buy higher capacity flash memory....
