Correct me if I'm wrong, but at a high level you appear to basically
just have a mapping of strings to values and you are then shifting all
of those values by a fixed constant (in this case, `z = 5`). Why are you
using a dict at all? It would be better to use something like a numpy
array or a serie

It is no
ast,
For what it's worth,
After
a = 5
b = 5
afloat = float(a)
bfloat = float(b)
afloat is bfloat
returns False.

Why is this disturbing? As you said, it'd be complete
Thanks MRAB, your solution works a treat.
I'm replying to the list so others can know that this solution works.
Note that sys.stderr.detach() is only available in >= 3.1, so one might
need to do some version checking to get it to work properly in both
versions. It also can mess up with the buf

Yes, it is a simplification and I am using numpy at lower layers. You correctly
observe that it's a simple operation, but it's not a shift it's actually
multidimensional vector algebra in numpy. So the - is more conceptual and takes
the place of hundreds of subtractions. But the example dies dem

Is there a recommended library for manipulating grapheme clusters?
In particular, in devanagari
क् + ि = कि
in (pseudo)unicode names
KA-letter + I-sign = KI-composite-letter
I would like to be able to handle KI as a letter rather than two code-points.
Can of course write an automaton to group bu
There is a trick that I use when data transfer is the performance killer. Just
save your big array first (for instance on and .hdf5 file) and send to the
workers the indices to retrieve the portion of the array you are interested in
instead of the actual subarray.
Anyway there are cases where m
