Hello,
I'm fairly new to Python, struggling to write in a more object-oriented,
functional style. I just wrote a function that takes two arrays
representing sine (y) and cosine (x) angle coordinates, and returns the
angle in degrees. I had initially written the function to take
array-like argume

The official Django docs is pretty detailed

You could also look at the Django book but it confesses to being written
for version 1.4 even though it goes ahead to assure us that it's not
outdated

Thanks to all for your response, I was not aware that the interpreter evaluated

In your second example, the peephole optimizer gets hold of it and
does the calculation at compile time:
Python 3.4.3 (v3.4.3:9b73f1c
As you are doing an operation on a literal, Python is computing the value
at import time, which occurs before your time.clock() calls run.
Basically, what you really wrote in your code is:
import time
a = time.clock()
42000...00 # Replace the ...
with z
Blast ;)

Hi all!
I am about to write an application (python3 in linux) that needs:
1. Display time series graphics dynamically changed as the application
runs, i.e. the graphics should reflect some internal variables states.
2. The same but for some network like diagrams. Basically nodes and
connections

Dear Group,
I am slightly new in Python Web Frameworks. I could learn bit of Django, Flask
and Bottle.
But I am looking for a good web based tutorial like Python or NLTK.
Somehow, I did not find documentations for web frameworks are very good, one
has to do lot of experiments even to learn bas

I think so. Either that or I am badly misunderstanding you.
I have code like:
if (condition):
do_something_needing_cleanup
code_executed_unconditionally
Now, how can I make sure cleanup happens? Actually, what I really would

if (condition):
