Hi,
I'm using python to run some lab equipment using PyVisa. When I read a
list of values from the equipment, one of the fields is 32 bits of
flags, but the value is returned as a floating point number, either in
ASCII format, or pure binary. In either case, since I'm using PyVisa,
it converts t
Hi,
okay, let me be more concise. The lab equipment has two formatting
modes, ascii, and float.
In ascii mode, it returns strings that represent the numeric value, so
e.g. 3.14 is returned as '3.14'. PyVisa, when set to read ascii mode,
will convert these strings to float with "visa.read_values
Ok, I figured it out...
The only way to get the flags is as a float, either through an ascii
string or a true float. The value of the float, however, is
representable as 24 bits of normal binary.
So for example, the value returned is +4.608400E+04
which is really an int, 46084, which is more eas
Actually that's probably the easiest way. I may want to use shorter
variable names :)
thanks

That looks pretty cool. I'll try it out.

Hi,
I'm using python 2.4 and windows XP.
I have two packages in the windows version of python in site-packages.
They are PyVisa and ctypes, and both live in
c:\python24\lib\site-packages
I'd like to move these to the cygwin version of python on the same
system. I tried copying the PyVisa and ct
Ok, thanks. I actually hadn't considered the build system, figuring
that function names, etc., would somehow magically be "exported" to
anyone wanting to use the .pyd library.

Hi all. I just downloaded and installed the new Office suite from MS
with their new 'ribbon' based UI. I think it's pretty cool and AFT*
for a new UI paradigm. I hope it sticks.
Anyway, I'm wondering how to implement a gui like this with Python. I
don't think wx or qt or gtk or tkinter support
Hi,
I'm writing a hand-written recursive decent parser for SPICE syntax
parsing. In one case I have one function that handles a bunch of
similar cases (you pass the name and the number of tokens you're
looking for). In another case I have a function that handles a
different set of tokens and so

Cool thanks, I'll check it out.

Hi, is there a way in python to place some sort of keyboard() type
statement which stops the script and puts you back at the console? I'm
looking for something like in matlab, where you place a keyboard()
command (I think), then you're in debug mode in the console, and you
type continue to re-ente
Hi, I was wondering how I may get a python function to know what its
name is without me having to write it manually? For example:
def func1():
print 'func1'
return True
def func2():
print 'func2'
return True
should be more like
def func1():
print
return T
Hi, I've been thinking about Python vs. Lisp. I've been learning
Python the past few months and like it very much. A few years ago I
had an AI class where we had to use Lisp, and I absolutely hated it,
having learned C++ a few years prior. They didn't teach Lisp at all
and instead expected us to
Cool, thank you. That's the answer I was looking for :)

Hi, I've written a top-down recursive decent parser for SPICE circuit
descriptions. For debugging purposes, I wanted each production
rule/function to know what its own name was, so at the beginning of
each rule/function, I make a call to inspect.stack()[0][3] (I think...)
and that fetches the name

Hi, I'm interested in using python to start writing a CAD program for
electrical design. I just got done reading Steven Rubin's book, I've
used "real" EDA tools, and I have an MSEE, so I know what I *want* at
the end of this; I just have never taken on a programming task of this
magnitude. I've s
Cool. thanks for the links. I've already looked around quite a bit,
and am very hesitant to just write more shit on top of other shit. The
idea behind this is it's completely mine. So yes, I have a tendency to
want to reinvent a few wheels, but I think it'll give me greater
satisfaction. The pr
Yes, I figured I should be pretty expert at what's out there first
before redoing something and making in inferior to the existing
solution. I took a quick peek at cadence courses, and they're out of
my personal price range. I have a new job coming up which should lead
into IC design after some t
Hi,
Actually, I've wondered about using a custom-rolled binary or
text-based database, vs. something that uses the OpenEDA standard, vs a
'real' database like sql. I guess my impression is that something like
SQL is not designed for something as multi-... uh, dimensional? as an
EE design. Perhap
Thanks for this. I'm enjoying this discussion and I'm learning a lot
about people's views and how they differ from mine.
However, I'm still wondering about my original post.
Can the experts please comment on python's usage for the following:
