Execute script from ipython
Hi all, I have a script "myscript.py" located in "/usr/local/bin" on my linux box. I can execute it in ipython with run /usr/local/bin/myscript.py but not with run myscript.py even though /usr/local/bin is in my $PATH and in my $PYTHONPATH. What should I do to correct this?

Re: Execute script from ipython
Thanks Chris! I tried using "!" instead of "run". It works but with a significant performance penalty.

optparse with numpy.array?
Hi all, I'm trying to use optparse to process command line parameters given to my program. It works as I expect for the types supported by optparse, i.e. int, float, string etc. but how can I pass a numpy.array or a list to my program? I have been searching for it but cannot find a good solution. By the way, I am a Python newbie so please be gentle... Best regards, Johan -- http://mail.python.org/mailman/listinfo/python-list
Re: optparse with numpy.array?
Thank you Robert, but what if I just want to create an array interactively, e.g. like m = array([1.0, 2.0, 3.0]), and pass it to my program? I tried extending optparse with a new type as explained in the link you gave me but I was not able to get it to work. Is it really neccessary follow that route just to pass an array? Lot's of people must have done this before!

Re: optparse with numpy.array?
Thank you James,
but I just can't optparse to accept an array, only integers, floats ans
strings.
My code looks like this
from optparse import OptionParser
parser = OptionParser()
parser.add_option('-t', '--dt', action='store', type='float', dest='dt_i',
default=0.1, help='time increment where lsoda saves results')
parser.add_option('-T', '--tstop', action='store', type='float',
dest='tstop_i', default=1.0, help='duration of the solution')
parser.add_option('-m', '--mass_vector', action='store', type='float',
dest='m_i', default=[1.0, 1.0], help='vector with lumped masses')
op, args = parser.parse_args(sys.argv[1:])
I want this to work for m_i = array([1.0, 2.0, 3.0]) but the optparse
complains that m_i is not a float.
Best regards,
Johan

Re: optparse with numpy.array?
Thanks,
James I will try your suggestion!
Robert, what mean with "interactively" is that i would like to create an
array in the ipython shell, e.g. with m_i = array([1.0, 2.0, 3.0]) or
by reading a file with values etc., and then execute my program with "myprog
-m m_i" and thus pass the array "m_i" to my program.
This is just an example. I would like to pass several arrays. My program
will be wrapped inside a loop and the arrays are updated
in each loop.
I have never heard of the "argparse" library. Do you think that it would be
better to use that in my case?
Best regards,
Johan

Multiple python installations on opensuse?
Hi all, I use the finite element package ABAQUS that is partly built around python 2.4.3. ABAQUS ships with its own version of python 2.4.3 but it comes without third party libraries, e.g. numpy and scipy. In order to load these modules into ABAQUS python I must install python 2.4.3. on my opensuse laptop. How can I do this without interference with my python 2.6 installation that I use for all my non-ABAQUS python work? Best regards, Johan -- http://mail.python.org/mailman/listinfo/python-list
