What exactly does the “u” do? “git push -u origin master” vs “git push origin master”
....
To see the difference, let's use a new empty branch:
$ git checkout -b test
First, we push without -u:
$ git push origin test

You asked me to pull without telling me which branch you

Python constructors and __init__

For example Python allows you to do:
class Test(object):
pass
t = Test()
t.x = 10 # here you're building your object t
print t.x
But if you want every instance of Test to have an attribute x equal to 10, you can put that code inside __init__:
