How to use pip with Python 3.x alongside Python 2.x
...
The approach you should take is to install pip for Python 3.2.
You do this in the following way:
$ curl -O https://bootstrap.pypa.io/get-pip.py

Simple argparse example wanted: 1 argument, 3 results
The documentation for the argparse python module , while excellent I'm sure, is too much for my tiny beginner brain to grasp right now. I don't need to do math on the command line or meddle with formatting lines on the screen or change option characters. All I want to do is "If arg is A, do this...
Is there a performance difference between a for loop and a for-each loop?
...for iterating over collections and arrays
for (Element e : elements) {
doSomething(e);
}
When you see the colon (:), read it as

Pointer to class data member “::*”
...< c1.speed << endl;
return 0;
}
As to why you would want to do that, well it gives you another level of indirection that can solve some tricky problems. But to be honest, I've never had to use them in my own code.
Edit: I can't think off-hand of a convincing use for pointers to membe...
Trying to mock datetime.date.today(), but not working
...ithin your today() will datetime.date.today be a different function, which doesn't appear to be what you want.
What you really want seems to be more like this:
@mock.patch('datetime.date.today')
def test():
datetime.date.today.return_value = date(2010, 1, 1)
print datetime.date.today()

How do I set the offset for ScrollSpy in Bootstrap?
... Thanks for the answer. Took me quite a while to realise that offset does not affect scrolling. This means anybody using a fixed-top needs to manually adjust in this manner.

How do you create a dictionary in Java? [closed]
...
Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default.
For example (using a HashMap):

What optimizations can GHC be expected to perform reliably?
GHC has a lot of optimizations that it can perform, but I don't know what they all are, nor how likely they are to be performed and under what circumstances.

Using Phonegap for Native Application development [closed]
...This is the method that's called once phonegap has loaded and is ready. $(document).ready or whatever you're used to, doesn't really apply here - unless you're only doing interface/hard-coded HTML stuff. If you're interacting with iPhone features, like GeoLocation, you will need to do everything a...
