Hi, Francesc:
The codes do not work. Guess you forgot something there.
Thanks.

Hi, All,
Coming from SAS and R, this is probably the first thing I want to do now that I
can convert my data into record arrays. But I could not find any clues after
googling for a while. Any hint or suggestions will be great!
Thanks a lot.

Hi, Pierre:
Thanks for the reply. I can now actually turn a big list into a record array.
My question is actually how to join related record arrays in Python. This is
done in SAS by MERGE and PROC SQL and by merge() in R. But I have no idea how
to do it in Python.
Thanks.

Hi, Everyone:
This is what I need to do everyday. Now I have to first save data as .csv file
and the use csv2rec() to read the data as a record array. Anybody can give me
some advice on how to directly get the data as record arrays? It will save me
tons of time.
Thanks in advance.

sometimes cannot even download all my
data via R due to its memory limit under windows. I thought NumPy might be the
solution. But I am not sure. Anybody can let me know whether Python has a
memory limit? or can I use virtual memory by calling some Python module?
Thanks in advance.

into a structured array? using array()
will turn it into a text array, afaik. it is even better if anybody can show me
some tricks to download the data directly as a structured array.
Thanks a lot for the help.

BTW: I am also interested in Python's ability to handle large data. Any hints
