Re: Non-blocking connect

Thanks Roy. I was just trying to understand someone else's code, but in the end it turns out that this was just a bug. What weirded me out was how injecting a print statement preventing the error from occurring, but now I get it. Without blocking, the connection handshake occurs in parallel after

Non-blocking connect

Code is at bottom. Basically, if I turn off socket blocking prior to connecting, I get a "Socket is not connected" error when I try to send data. However, if I do not turn off blocking, OR if I place a print statement anywhere before the send call, it works! WTF? I'd like to understand what's goin

Re: Can you determine the sign of the polar form of a complex number?

Just to clarify what I'm after: If you plot (-3)^n where n is a set of negative real numbers between 0 and -20 for example, then you get a discontinuos line due to the problem mentioned above with fractional exponents. However, you can compute what the correct absolute value of the the missing poi

Can you determine the sign of the polar form of a complex number?

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 ) |z

negative base raised to fractional exponent

Does anyone know of an approximation to raising a negative base to a fractional exponent? For example, (-3)^-4.1 since this cannot be computed without using imaginary numbers. Any help is appreciated. -- http://mail.python.org/mailman/listinfo/python-list

mx.DateTime to datetime.datetime

Is there a constructor for an mx.DateTime object which takes a datetime.datetime object? It seems like a pretty common thing to do but I didn't see such a constructor in the mx.DateTime docs. Thanks -- http://mail.python.org/mailman/listinfo/python-list
