Re: [Tutor] Video file metadata? (MP4/WMV)

I can't seem to find a simple description of the MP4 sepc... it might be because there is not one. :) That being said, what is the correct way to parse binary files in Python? - Original Message > From: Alan Gauld <[EMAIL PROTECTED]> > To: tutor@python.org > Sent: Tuesday, March 4, 2

Re: [Tutor] Video file metadata? (MP4/WMV)

Don't think so. Do you have any cmdline tool to update the meta data? Alternativly you can naturally embed Win32 components and control them with Python, but I'm not a Windows guy. Andreas Am Dienstag, den 04.03.2008, 14:10 -0800 schrieb Allen Fowler: > Hello, > > I have several hundred WMV vi

Re: [Tutor] help with slice

What you probably want is: [elem_list[2] for elem_list in List] If you are not sure that the list have at least three elements, you can use something like this: [(elem_list + [None, None, None])[2] for elem_list in List] Which will use None as a default value. Andreas Am Dienstag, den 04.03.2

[Tutor] Video file metadata? (MP4/WMV)

Hello, I have several hundred WMV video files with bad embedded author/title/date information. However, the correct information is correctly encoded in the file name.. i.e. "title-author-date.wmv" Seems like the a great job for Python. :) Also, I am about to convert these fiiles to MP4 f

[Tutor] Translate this VB.NET code into Python for me?

I thought I'd dip into .NET by downloading the free Microsoft Visual Basic 2005 Express Edition, and start working through _Beginning Visual Basic 2005 Express Edition_, by Peter Wright (Apress). By the second chapter I've begun to suspect that GUIs aside, Python is a lot simpler to write. Coul

Re: [Tutor] sorting objects on two attributes

Here is a version based on Andreas' solution using groupby() that avoids the decorate-undecorate by using the key= parameter for the second sort: l.sort(key=lambda x: (x.content_type, x.submit_date)) t = [ list(items) for key, items in itertools.groupby(l, key=lambda x: (x.content_type)) ] t.sort
