Install problem on AIX
by chrishad95＠yahoo.com Dec. 1, 2003

Dec. 1, 2003

I am installing Python 2.3.2 on AIX 4.3.3 I get to the point where I'm ready to "make install" and I get an error, with no idea how to get around it. Here's the tail end of the output: Compiling /usr/local/lib/python2.3/xml/sax/saxutils.py ... Compiling /usr/local/lib/python2.3/xml/sax/xmlreader.py ... Compiling /usr/local/lib/python2.3/xmllib.py ... Compiling /usr/local/lib/python2.3/xmlrpclib.py ... Compiling /usr/local/lib/python2.3/zipfile.py ... make: 1254-004 The error code from the last command is 1. We tracked it down to a script called compileall.py or something close to that which seems to be doing the "Compiling"

Turning off warnings
by Paulo Pinto Dec. 1, 2003

Dec. 1, 2003

Hi, I need to generate a temporary name for a file and pass it as argument to a shell script. Now when I use os.tempnam() or os.tmpnam() I get a runtime warning about security issues. I am well aware of them, but in the context of this application I really don't need to care about it. Is there any way to turn the message off? Thanks, Paulo

hi, Does anyone know how to read-in several files and then batch all together into a *.zip format? I've looked at the gzip module but I'm not sure how to use this with several files. Any help gratefully received! Rob

RE: Bug in glob.glob for files w/o extentions in Windows

On that basis Python also 'special-cases the snot out of a period': try win32api.FindFiles('*.') to get the same behaviour as dir. More accurate would be to say that the operating system has consistent but weird behaviour, since it is below the application level that trailing dots are stripped from filenames and ignored from file patterns. The only way to avoid it on Windows is to retrieve all the filenames and then perform your own pattern matching on them. glob.glob is bypassing the operating system's filename matching to provide behaviour which is consistent across different operating systems, but inevitably this means that it doesn't match some platform's standard behaviour. -- Duncan Booth duncan(a)rcp.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure?

Re: compile(unicode) & source encoding

I think it is because Just found that the most straight-forward thing to do: UTF-8 supports all Unicode characters, and you have to choose *some* encoding, as the resulting byte strings need to be encoded somehow. In addition, anybody desiring a different encoding can explicitly invoke .encode() > 2. Why there is now option to define encoding of source passed to > compile function? No, although this should be implemented. It is not implemented at this point because it is very hard to do, and I have not found a good way to do it, yet. Regards, Martin

You need some raw string quoting there. os.path.exists(r'\\computer\d$\c++') would check for the existence of a directory c++ on drive D of the computer named 'computer', provided you have administrative access to the remote computer. The drive letter shares c$ (and d$ etc. where there is more than one drive) are created automatically and are only accessible to administrators. The UNC pathnames being used mean that there is no need to mount the drive before accessing it. os.path.exists(r'\\computer\d$') will return False whether or not the share exists, however os.path.exists(r'\\computer\d$\\') will return True if the share exists. Note that you need two trailing backslashes even if you don't use the raw quoting. I tried creating a file called FILE_TO_DELETE.JPG in a directory called C++ on a remote machine. I checked the existence of both the file and directory using os.path.exists, and then removed first the file and then the directory using os.remove. Both operations worked as expected, so the '+' character in the filename is not a problem (Python 2.3). I suspect the OP must have something else wrong, possibly a confusion over backslashes, or possibly just insufficient access to the C++ directory (just because you have access to the admin shares doesn't mean you necessarily have full access to all the directories). -- Duncan Booth duncan(a)rcp.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure?
