problem with eval and time
Dear all, I would like to convert tstr to representation of time, but encounter the following error. Is there a simple way to get what I want? Thanks. >>> import time >>> tstr = str(time.localtime()) >>> eval(tstr) Traceback (most recent call last): File "", line 1, in File "", line 1, in TypeError: structseq() takes at most 2 arguments (9 given) >>> sys.version '2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)]' Wincent -- http://mail.python.org/mailman/listinfo/python-list
Re: problem with eval and time
Thanks. I fetch data from social networking sites and want to mark the time of access. I store all the information in a redis database, which converts everything into strings and I need to convert those strings back to original python objects when analyzing the data.

Re: How can i use Spread Sheet as Data Store
If you want to write to a csv file, the other option is savetxt in
NumPy module.
