Hi everyone.
Can someone suggest a python module so that it would be able to do a video
processing and adding watermark in video?

That is technically correct, you could do that. That's a good

Hi Python Tutor people :)
Who leads this group?
I put together a global meeting (via voip) that
1) has an interest in Python,
2) and that Python learners, users & developers might be interested in.

is different to

Which was why I thought it worth pointing out that the if/else
could be used.
I'd prefer the form:
flag = not not (someValue or another)

That's a construct you might commonly find in languages like C, but I
don't think it's very pythonic. If you want to convert your result to
a bool, be explicit about it:

any observations might be helpful. For the display of database contents I
have the following problem:
Database querys will return data to me in tuples of the following sort:
each tuple has a unique id, a parent id, and a type.
a parent id of 0 indicates that the element has no parent.

When I write the blob/binary data to a file and give it its original file name
"customer1.rtf", I am expecting the application to read the binary data into

Example:

In general, there's 2 solutions to your "unflattening" problem.
A) The general solution: Keep track of the depth you're at, and add
tabs/spaces ('\t' * depth) as necessary.
B) The xml solution: Use (for example) the dom.minidom module, and create a
new "ul node" and populate it with children, at
Thanks for the suggestions, everyone. For now, more as a way to

want, you can type in an ip and connect to the server at that ip

Eek! no I'd just cast to a bool:
flag = bool(someValue or another)
but the if/else form has the Pythonic virtue of explicitness.

Are you arguing that the if/else form is better than simply casting to bool
because it is more explicit? You could ha

No, I'm simply offering a reason to use if/else in the general sense.
In practice, for this specific case, I'd go with the bool(expr) form.
