I have visited Vim website , script section and found several synthax checkers for python. But which one to choose ? I would prefer something that supports python 3 as well, even though I code in python 2.6 currently.
Do all these checkers need a module...
Python Ternary Operator
I'm just getting into Python and I really like the terseness of the syntax. However, is there an easier way of writing an if-then-else statement so it fits on one line?
if count == N:
hand = deal_hand(HAND_SIZE) # random init
cmd = raw_input('Enter n to deal a new hand, r to replay the last hand, or e to end game: ')
if cmd == 'n':
hand = deal_ha...
What does the * operator mean in Python, such as in code like zip(*x) or f(**k)?
How is it handled internally in the interpreter?
Does it affect performance at all? Is it fast or slow?
When is it useful and when is it not?
Should it be used in a functio...
I've heard it said that multiline lambdas can't be added in Python because they would clash syntactically with the other syntax constructs in Python. I was thinking about this on the bus today and realized I couldn't think of a single Python construct th...
How do you express an integer as a binary number with Python literals?
I was easily able to find the answer for hex:
How do you use literals to e...
I have a long line of code that I want to break up among multiple lines. What do I use and what is the syntax?
For example, adding a bunch of strings,
e = 'a' + 'b' + 'c' + 'd'
and have it in two lines like this:
e = 'a' + 'b' +
'c' + 'd'
Terminating a Python script
I have a simple Python script that I want to stop executing if a condition is met.
done = True
# do other stuff
Essentially, I am looking f...
I'm fairly new to python and following along with part 4 of the tutorial for the Django framework here. I'm trying to implement generic views for the polls app--my code seems correct (as far as I can tell), but when I try to vote, I get a NoReverseMatch E...
Python: Behaviour of increment and decrement operators
I've always laughed to myself when I've looked back at my VB6 days and thought, "What modern language doesn't allow incrementing with double plus signs?":
I have a string that looks like '%s in %s' and I want to know how to seperate the arguments so that they are two different %s. My mind coming from Java came up with this:
'%s in %s' % unicode(self.author), unicode(self.publication)
But this doesn't w...
