Backslashes inside of variable
by Phoebus Nov. 24, 2003

Nov. 24, 2003

I am running Python 2.2 on Win2k. I have a program which writes a filename, with backslashes to a file, along with other stuff. I read the file in using readlines() and put each line into a variable. My problem is I want to use the filename, but I can't use it because of the backslashes. I know about doing open(r"d:\test\file.txt","w") or even open(`d:\test\file.txt`,"w"), but the filename is inside of a variable so when I do open(filename,'w'), I have problems. Can anyone help? Thanks, Steve --

Re: [Tutor] graphics in python

Although I'm new to Python myself, I've been looking for ways to do graphics as well. Here are two projects I've found that I'm exploring... A new 3D engine written specifically for use with Python called Soya 3D. It's at: http://oomadness.tuxfamily.org/en/soya/index.html For 2D graphics (and other game related stuff like checking a joystick etc), there's pygame: http://www.pygame.org/ Bob >From: Danny Yoo <dyoo(a)hkn.eecs.berkeley.edu> >To: pytutor <pytutor(a)indiatimes.com> >CC: tutor(a)python.org >Subject: Re: [Tutor] graphics in python >Date: Sat, 22 Mar 2003 13:21:24 -0800 (PST) > > > >On Sat, 22 Mar 2003, pytutor wrote: > > > I am a graphics programmer.

BayPIGgies: Silicon Valley-San Francisco Bay Area Python Users Group When: December 11, 2002 @ 7:30pm Where: Stanford University, Palo Alto, CA Agenda: Newbies' Nite Speaker: (everyone!) Due to popular demand, we are having another Newbie Night (e.g. April 2002). This is the chance for all Python programmers to bring their friends and colleagues who should hear about Python. It is also for those who want to or are picking up Python and have questions! We will have a good number of Python experts who will try and help you out. Perl and Java experts are welcome too, as many Python developers also have experience there and can give you an honest comparison. The format is this: Wesley (or Danny) will give just a short half-hour intro presentation on Python to beginners followed by a quick demo, and then we will open it up to everyone for Q&A. Mingling and networking will bring our meeting to a glorious conclusion. :-) # NOTE: the next meeting on January 8, 2003 will be not be at the usual # place... stay tuned for a location update. # Call For Talks: We are actively seeking speakers for BayPIGgies! If you would like to give a talk at one of our 2003 meetings (any Python related topic), contact us to coordinate! more info including directions: http://www.baypiggies.net hope to see some of you next Wednesday! -wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall PTR, � 2001 http://starship.python.net/crew/wesc/cpp/ Silicon Valley-San Francisco Bay Area Python Users Group (BayPIGgies) http://deirdre.org/baypiggies wesley.j.chun :: wesc at deirdre.org cyberweb.consulting : henderson, nv : cyberweb at rocketmail.com http://www.roadkill.com/~wesc/cyberweb/

I have the setup file and the script file. here they are: # setup.py from distutils.core import setup import py2exe setup(name="test", scripts=["test.py"], ) #test.py print "THIS IS A TEST" And When I start the setup program, it says: usage: test.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: test.py --help [cmd1 cmd2 ...] or: test.py --help-commands or: test.py cmd --help error: no commands supplied Am I missing something that's completely obvious? I apologize for being kinda thick but I'm trying to get it to work. Thanks

If not global, how?
by vicki＠stanfield.net March 31, 2003

March 31, 2003

In the app that I am developing, I have some callbacks that need data from other methods. I am trying to figure out how to make that data available without making it global. Here is an example: This class is instantiated. class EntryClass(Pmw.EntryField): def __init__(self, parent=0): Pmw.EntryField.__init__(self, parent) def SendCommand(command): for command in ('\x09','\x06'): port = serial.Serial(0, 9600, 8, 'N', 2, timeout=2) port.write(command) old=outputbox.getvalue() new=string.join([old, hex(ord(command))]) outputbox.setvalue(new) input=port.read() print input if input: returnedval=hex(ord(input)) if returnedval: print returnedval old=outputbox.getvalue() new=string.join([old, returnedval]) outputbox.setvalue(new) port.close() def Callback(self): value=self.getvalue() print value if value SendCommand(value) ------------------------------------ As you can see, I need to call SendCommand from the callback. Since it is not an instance within the class, I can't use EntryClass.SendCommand. If I move the call to SendCommand into the main code, I don't think I can be sure that it was just called and has a value that I actually want to send out. I realize that I am probably making this much harder than it is, but I am stuck. Can someone help me fix this one? --vicki

I am pretty sure that __call__ is what I need, but I am still unclear how to implement it in my case. Is there some documentation that you can point me to? --vicki
