Hi,
Wow. Lots of feedback. REALLY GOOD FEEDBACK!
This was my first question to this list. Let me clarify my question.
I want to use tst.py as follows:
tst.py input-file output-file OR
cat data-file | tst.py - output-file OR
cat data-file | tst.py output-file
tst.py input-file output-file works

correct.
I've been trying to find out how you tell if there's data in stdin
Same way you tell if there's data in any file/stream - you read
from it.

Are you planning to pipe data to a python program? If so please
specify and you will get more complete answers.
Specifically I am thinking you want information pertaining to
subprocess in the standard library.

That's true of any program on a POSIX-compliant operating system.

Hi,
When you run a python program, it appears that stdin, stdout, and stderr are
opened automatically.
I've been trying to find out how you tell if there's data in stdin (like when
you pipe data to a python program) rather
than in a named input file. It seems like most/all the Unix/Linux

The book I have says when you anticipate that you will be working with

Thanks.
It means, you take a datetime object and then using a timedelta object,
perform the addition, the language takes care of changing the date if the
time crosses midnight.
WOW... this makes life a lot easier..

Hi ,
I have a question:
Is it possible to add seconds to a datetime object and get the result as a
new datetime object. I mean when we keep adding, for example, 3600 seconds,
the date will get changed after 24 iterations. Is it possible to carry out
such an operation ?

No, it simply assigns the value returned by areaCirc to

areaCirc assigns
