General tip when you think you've found a bug: Cut out everything that
isn't part of it. In this case, the enumerate has nothing to do with

No, this is not a bug in Python. There is a limitation of floating
point arithmetic in *all* languages, on *all* computers. Python 3 may
be the first to let you see this limitation, but it's always bee

I think I found a strange bug in python 3.4.1,
fresh install of
https://www.python.org/ftp/python/3.4.1/python-3.4.1.amd64.msi
and a fresh install of
https://www.python.org/ftp/python/2.7.7/python-2.7.7.amd64.msi
to compare it to.

Congratulations.
I can't find the details of PyPy3's unicode implementation documented
anywhere. Is it equivalent to:
- a Python 3.2 narrow build
- a Python 3.2 wide build
- PEP 393
- something else?
Cheers,

In C it is customary to do all sorts of sanity checks in advance.
Validating user input is an example. We can call this "to ask permis

Please double-check by adding
assert x.dtype == np.float64
assert y.dtype == np.float64
If none of these assertions fail try to make a minimal script including some

Hi folks,
I'm trying to plot a 2D histogram but I'm having some issues:
from pylab import *
import numpy as np
import netCDF4
hist,xedges,yedges=np.histogram2d(x,y,bins=10)
extent=[xedges[0],xedges[-1],yedges[0],yedges[-1]]
imshow(hist.T,extent=extent,interpolation='nearest')

Hi folks,
Instead of colouring the entire bar of a histogram i.e. filling it, I would
like to colour just the outline of the histogram. Does anyone know how to do
this?
