> How do we decide whether a level of complexity is Ok or not?
I don't understand your question, but here are better ways to do what
you do:
>>> a = {'a': 2, 'c': 4, 'b': 3}
>>> for k, v in a.iteritems():
... a[k] = v + 1
...
>>> a
{'a': 3, 'c': 5, 'b': 4}
>>> b = dict((k, v+1) for k, v in a.iteritems())
>>> b
{'a': 4, 'c': 6, 'b': 5}
The first modifies the dict in-place, and the second created a new
dict.
In Python 3 those lines become shorter:
for k, v in a.items():
{k: v+1 for k, v in a.items()}
