Does anyone know of an approximation to raising a negative base to a fractional exponent? For example, (-3)^-4.11111 since this cannot be computed without using imaginary numbers. Any help is appreciated.

Is there a module that can pull str values for say the last 3 months? Something like: print lastMonths(3) Thanks

To compute the absolute value of a negative base raised to a fractional exponent such as: z = (-3)^4.5 you can compute the real and imaginary parts and then convert to the polar form to get the correct value: real_part = ( 3^-4.5 ) * cos( -4.5 * pi ) imag_part = ( 3^-4.5 ) * sin( -4.5 * pi )

Hi, I would like to use python to start an terminal, e.g. xterm, and login on a remote machine using rsh or ssh. This could be done using 'xterm -e ssh machine', but after the login I would like to jump to a given directory. Does anyone have an idea how to do this with python? Regards! Fabian

Hi all, I'm new to this group so I don't know if this question has been posted before, but does anyone knows about linear/integer programming routines in Python that are available on the web, more specifically of the branch and bound method. Thanks, Jorge Velasquez

Does anybody know of a decent HTML parser for Jython? I have to do some screen scraping, and would rather use a tested module instead of rolling my own. Thanks! GP

There is a useful module http://www.purecode.com/~tsatter/python/README.txt (at that URL) with a function that takes seconds from the epoch and a time zone and returns what is basically a datetime object. My question is how to I display the seconds...

Hi! Is there any possibility/tool to automatically organize the imports at the beginning of a module? I don't mean automatic imports like autoimp does as I like seeing where my objects/functions really come from. For the same reason I don't like "from foo import *". The downside is that you have a rather verbose import section at the

I'm looking at doing some currency calculations in some Python code integrated with a C++ application. I want to be able to come up with the same values I get in an Excel spreadsheet.
