Solved the issue, by injecting the query into the cmd line. Shell script
worked fine as if I was cutting and pasting to the prompt. Seems to still be
something with the subprocess receiving and exit code before or when the query
finishes, just when I ask to to read from the .SQL file.

Oscar I can confirm this behavior from terminal.
AND this works as well, simulating exactly what I'm doing permissions wise, and
calling sudo python test.py below

Oscar, seems you may be correct. I need to run this program as a superuser.
However, after some more tests with simple commands... I seem to be working
correctly from any permission level in python Except for the output write
command from the database to a file. Which runs fine if I past
Thanks for verifying this for me Steven. I'm glad you are seeing it work.
It's really the strangest thing.
The issue seems to be with the " > outfile.txt" portion of the command.
The actual command is running a query on a verticalDB and dumping the result.
The EXACT command run from the comm
Thanks! I am using .txt extensions. Sorry for being a little vague.

Example of the issue for arguments sake:
Platform Ubuntu server 12.04LTS, python 2.7
Say file1.txt has "hello world" in it.
subprocess.Popen("cat < file1 > file2", shell = True)
subprocess.call("cat < file1 > file2", shell = True)
os.system("cat < file1 > file2")
I'm finding that file2 IS crea

Hi,
I'm looking to generate x alphabetic strings in a list size x. This
is exactly the same output that the unix command "split" generates as
default file name output when splitting large files.
Example:
produce x original, but not random strings from english alphabet, all
lowercase. The lengt

Is this possible or is there a better way. I need to create a new
class during runtime to be used inside a function. The class
definition and body are dependant on unknows vars at time of exec,
thus my reasoning here.
class PosRecords(tables.IsDescription):
class A(object):
self.__init__(s
This is excellect advise, thank you gentelman.

We can't really, in this arena make assumtions about the data source.
I fully agree with your point, but if we had the luxury of really
knowing the source we wouldn't be having this conversation. Files we
can deal with could be consumer data
Hello,
I'm importing large text files of data using csv. I would like to add
some more auto sensing abilities. I'm considing sampling the data

How can you make python interpret a string (of py code) as code. For
example if you want a py program to modify itself as it runs. I know
this is an advantage of interpreted languages, how is this done in
python. Thanks.

True! it is rediculous/insane as I mentioned and noted and agreed with
you (in all your responses) and was my problem, however, not wrong
(same result), as I was just simply noting (not to be right), although,
yes, insane. Thanks again.

No! when you mult a vector with itself transposed, the diagonal of the
resulting matrix is the squares of each error (albeit you do a lot of
extra calc), then sum the squares, ie trace(). Its a ni
