London 2.0 rc5
by Simon Brunning May 3, 2006

May 3, 2006

Sam Newman has organised London 2.0 rc5 for the evening of May the 3rd at The Olde Bank Of England, 194 Fleet Street, London EC4A 2LT. The demos at rc4 were 100% Python related, so the PSUs cunning plan to infiltrate and take over these events is clearly running to schedule. BTW, if you are using Google Calendar (<http://www.google.com/calendar/>), I've set up a public Calendar called "London Python", into which I'll put any London based Python related events I come across. If you are not using Google Calendar yet, you can find an RSS feed for it at <http://www.google.com/calendar/feeds/8he6lf5a3b0pmbc2c2740f3e0g@group.calen…>. If you are not using Google Calendar *or* an RSS reader yet, well, you are probably too 20th century to be interested in any of the events in any case. ;-) -- Cheers, Simon B, simon(a)brunningonline.net, http://www.brunningonline.net/simon/blog/

I'd be interested in a Manchester Python 2.1b on 3/May -- and the Lass sounds fine to me! >>> Michael <ms(a)cerenity.org> 24/04/2006 23:39:42 >>> Hi! If so, was the Lass a good idea, or does anyone have a better idea? Would people prefer a different venue? ------------------------------------------------------------- This message has been scanned for all viruses by Sophos Sweep <<<<GWAVAsig>>>>

I'm not going to the ACCU conference
by Duncan Booth April 18, 2006

I didn't get myself organised to sign up for the conference this year, but does anyone fancy an evening meet-up for a drink and/or food somewhere in Oxford outside the confines of the conference venue?

by susan walthew April 2, 2006

April 2, 2006

Hi there, I want to buy some Valium Roche 10mg - 30 tablets - for a funeral I'm going to in 2 weeks time! Before I put in an order for some - how long do you take to ship them to your customers and how much will they cost in British sterling? I'm not properly set-up with Paypal yet - until in a few days, so would you accept a cheque for the item? Please let me know as soon as you can! Thanks, Susan Walthew

Python, VB math simple problem
by Mr X April 1, 2006

April 1, 2006

Hi looking for help with what should be a fairly simple Python problem, relating to VB inter-operability. Got a great response from a fellow named Matt at help(a)python.org, pointed me in some good directions - some areas, concerns still foggy on, the below thread is included.... any feedback on this simple dilemma would be very appreciated. Thanks, D thread follows below; ------------------------------------ To: help(a)python.org Subject: Problem with Python math functions and VB Date: 3/30/2006 9:39:28 PM Download Message Display Headers Printer Friendly Previous | Next Wondering if you might either know how to solve the following. I've a background in Visual Basic, and am using an old version, 4.0, it compiles to a smaller executable which I prefer. I find myself in an odd situation, needing a very simple yet powerful capability of Python for a VB app Im working on. Simply, a large 300 digit number is divided by a smaller number ranging from 1 to 3 digits. I.e; This large 300 digit number is generated as a string from the VB app, and I want to input this somehow from the VB app directly to Python for simple math operations. Where; x = 300 digit number, y = divisor ( say '37') x / 37 I want to divide x by y but I want the remainder of this division to at least 3 or 4 decimal places, so my Python script at the command line; x %y /y. = z So now I want to take the resultant, the full number plus its remainder, and I want to round this number up to the next highest number and divide it by the same constant; z rounded up to next highest number (never the lowest) so z /y = z Long Remove the 'L' at the end, round up the last digit of z = Z Then; Z %y /y. = a Then I want the last five digits of z (not Z) and a truncated at the end, so the last digit before the decimal point and the four digits past the decimal point printed to a text file. I want to be able to open the text file with the VB app and use this data as inputs. ========== Ok, so here is my dilemma, I know VERY litle about Python and a fair bit about VB. Ideally, I'd love to be able to simply have some extremely small executable that just accepts inputs does the calculations above and then spits out the outputs. If it were possible to write some simple lines of math code in Python and then compile these scripts in Python to a Windows compatible executable,that would be fantastic. If I could simply have my VB app, 'call' the name of the tiny Python executable, and then the Python executable just automatically looked for a named text file (created by the VB app) and extracted the 300 digit number from this, then performed the calcs, then spit this data out as a new text file name it created, which I could then use the VB app to open and read from, THAT would be ideal. However, I don't know if Python can compile scripts to an exe? If it can how could I find out how to do this? If it doesn't, how could I get VB to directly pass commands to the Python command line and then automatically extract the outputs? Shelling out from VB to Python would be tough to the command line I think, since the Python command line uses the 'Edit / Mark, Paste' approach to inserting, copy inputs, outputs and this would be virtually untenable, as far as I can tell to automate in a VB shell out routine. So basically, how the heck can I access Pythons ability to perform simple calculations on very large numbers, easily, from within VB 4.0 ? There must be a way, it seems like such a simple think to do, especially since the actual math operations are so simple, straight forward, and would never change..... Any ideas? ------ Matthew, thanks for your response. <-----Original Message-----> >From: Matthew Dixon Cowles >Sent: 3/31/2006 9:41:18 AM >To: durango(a)mail2world.com >Cc: help(a)python.org >Subject: Re: [Python-Help] Problem with Python math functions and VB >I'm sure that there's a way to do that, but I'm not familiar with >Visual Basic and I don't know what inter-process communication >facilities it offers.

Hundreds of digits of floating-point precision is a lot. Could you explain that a bit more, sorry Im not sure what you mean by 'out of the box' ? If I run the Python command line screen in windows and manually type out a very large number, say 180 digits; where 'X' = very large number; X %37 /37. returns what Im after, value wise..... but of course I don't want to do this manually each time for every dividend. >You might find that one of the Python modules that let you use an >extended-precision library would do what you want.

I assume that Visual Basic has an easy way to start a >program and supply it with arguments, so you could have your Python >program get its inputs from sys.argv. What is sys.argv ? Thats really good news. In fact, all I really need for the moment is a python executable that; ================ PYTHON ALGORITHM ABSTRACT a) opens a text file b) reads a string from the file, which is a very large number c) performs simple arithmetic operations; X %37 /37. = y (four digit remainder after decimal point) X /37 = w (quotient as long, the resulting output is stored as a variable, the 'L' suffix tagged on the end of this resultant then gets removed. then the last digit in the quotient resultant string is increased in value by one, rounded upwards = 'Z' then Z %37 /37. = a then, y and a are printed to a text file with hard returns between them. Thats it, thats all I need to do. =================== >Alas, it's not going to be extremely small. There isn't a compiler >from Python to machine code.

Py2exe is at: > >http://www.py2exe.org/ the most important thing is the functionality, I'll sacrifice size if I have to. My guess is this should work based on your comments, because perhaps all I really have to do is have VB dump out the value of the Very large number, `180 to 300 digits or so', to a text file, which then becomes the input data for the Python executable, and then if I simply call the name of the Python executable from VB as an instance, then the Python App runs, spits out the data as a new text file, then the VB app goes and opens the new text file and reads in the values, and voila! There it is. I'm pretty sure I can call the Python app from VB....... the alternative to all this would be to try and feed Python scripts directly to Python from VB, which I have NO idea how to do or where to begin.... and am guessing would be much more messy... I haven't programmed in Python, how would the "PYTHON ALGORITHM ABSTRACT" I describe above look like, code wise? Is this fairly easy for you to describe? >It may be that Python isn't the best solution for you here. Are there >extended-precision libraries for Visual Basic? Alas, none that I know of that are reliable and not incredibly expensive, been looking for years, plus Im hooped because I have to work with VB 4.0 instead of 6 +, guh.... >Regards, >Matt Matt..... good name, why do I always seem to get along with Matts, you people keep popping up in my life and its always a blast!
