question on write.table

Hi, I have a question on write.table: I have a data.frame called t7 as below:
dim(t7)
[1] 14015184 6
t7[1:5,]
uci uce par line graphical.forms stems 1 0 0 0 0 active activ 2 0 0 0 0 policy polici 3 0 0 0 0 wc PC 4 0 0 0 0 eff elf 5 0 0 0 0 icn ICC I want to write the contents of t7 into a file, which can be read later by a python program. So I used: write.table(t7,file="map") , which of course takes forever. Is there another way to make it finish in a standable time?
If the only purpose is to write something that python can read, might it not be more expedient to teach python some other data format that R can generate easily? E.g. dump() or save(..., ascii=TRUE) ?
I have to use old R version since I need to use ttda package.
