Commas

In method definitions or method calls we use following syntax:

def myMethod(myarg1, myarg2):
    pass
myMethod("b1", "b2")

And not:

def myMethod(myarg1,myarg2):
    pass
myMethod("b1","b2")

One liners

One liners are good only if they are very small and trivial. Something like this is ok:

list = [bar for bar in foo if bar == 'lala']

If the formating or condition is too big, then split up like this:

list = []
for bar in foo:
    if bar == 'lala' and ... or ... and ...:
        list.append("...%s..." % bar)

Indention

We use 4 space indention.
