How to run a dos executable from python

[lblr33]

I have an executable (e.g. myprog.exe) which takes some set number of
arguments.

This command works ok:
os.system(r"c:\tmp\myprog.exe arg1 arg2 arg3")

The problem is that the path to the program and the arguments are
variable at runtime so I need to pass them as arguments.

Thanks

Running a DOS exe file from python

[lblr33]

I would like to execute a windows program from python and wait for it
to finish before returning to the python script.

The script I want to run has a set number of arguments.

The following does work fine:
os.system(r"c:\tmp\myprog.exe arg1 arg2 arg3")

The problem I have is that the path to myprog.exe and the arguments are
variable so I need to pass them in as arguments to myprog.exe.

Thanks

ODBC

[lblr33]

I would like to connect to an Oracle database.  In python version 2.1 I
used the following code and it worked fine.  When I run the code in
version 2.4 it says that the odbc moduled does not exist.  How do you
connect to an Oracle database in v2.4?

oradb=odbc.odbc('oracle/scott/tiger')
stmt='select project_id from s_projects'
cur=oradb.cursor()
cur.execute(stmt)
for rec in cur.fetchall():
print rec[0]
cur.close()

Thanks

I posted this earlier on yahoo groups and then realized that the most
recent post was 2003.  What I didn't realize is that it posted to this
group so I posted it again.

The other post is:

cx_Oracle entry point error

[lblr33]

I downloaded cx_Oracle from
http://www.cxtools.net/default.aspx?nav=cxorlb and selected the windows
installer for Oracle 8i, Python 2.4

>From the readme.txt file:
BINARY INSTALL:
Place the file cx_Oracle.pyd or cx_Oracle.so anywhere on your Python
path.

So I tried this and set PYTHONPATH.

I then created a script called ora_conn.py with one line:
import cx_Oracle

When I run the script (c:\python24\python.exe ora_conn.py) I get this
error in a pop-up box:

"The procedure entry point OCIEnvCreate could not be located in the
dynamic link ligrary OCI.dll

The bottom line of what I want to do is to connect to an oracle
database without having to create an ODBC connection on the individual
PC.

Any ideas?  Thanks.
