Printing HTML

How can I print (as in laser printer, not the python print statement) HTML from Python (actually it doesn't have to be HTML - it's tabular data with some rows/columns highlited). The project currently uses Python 2.4 with wxPython and pywin/winpy (whatever it's called, for MS Access ODBC), so i

Re: os.path.join - Isn't working

Wow, sorry I sent that a little too fast. I just had to remove the \\ before the graphics. Thus this did work: os.path.join('C:\\Documents and Settings\\Gregory','graphics\\knight\\been hit e0001.bmp') -Greg On 1/27/06, Gregory Piñero <[EMAIL PROTECTED]> wrote: > Would someone mind explaining

os.path.join - Isn't working

Would someone mind explaining this seemingly strange behavior of os.path.join to me? [Dbg]>>> os.path.join('C:\\Documents and Settings\\Gregory','\\graphics\\knight\\been hit e0001.bmp') >>'\\graphics\\knight\\been hit e0001.bmp' And what is the right way to reference this path relatively? -- Gr

We have zipimport, how about dllimport?

I may be on particularly potent crack, but I was wondering whether it would make sense to distribute python code in DLLs so that the memory occupied by the bytecode would be consumed only once even if there were multiple processes using the same bytecode. Or is there another way to accomplish code

Re: writing large files quickly

Oops. I did mean fd.write(block) The only limit is available memory. I've used 1MB block sizes when I did read/write tests. I was comparing NFS vs. local disk performance. I know Python can do at least 100MB/sec. -- http://mail.python.org/mailman/listinfo/python-list
