STY: Giant whitespace cleanup.

2013-08-18T17:20:45+00:00

Now is as good a time as any with open PR's at a low.

ENH: Make var and std methods raise error when ddof too big.

2013-08-13T04:33:56+00:00

Currently the results may be infinite or negative. Instead, raise a
ValueError in this case.

BUG: Make mean, sum, var, std methods return correct scalar type.

2013-08-13T04:33:56+00:00

The return type could differ depending on whether or not the value
was a scalar.

MAINT: Clean up core/_methods.py and core/fromnumeric.py

2013-08-13T04:33:55+00:00

Use issubclass instead of issubdtype.
Add some blank lines.
Remove trailing whitespace.
Remove uneeded float casts since true_divide is default.
Clean up documentation a bit.

MAINT: Separate nan functions into their own module.

2013-08-13T04:33:55+00:00

New files lib/nanfunctions.py and lib/tests/test_nanfunctions.py are
added and both the previous and new nan functions and tests are moved
into them.

The existing nan functions moved from lib/function_base are:

    nansum, nanmin, nanmax, nanargmin, nanargmax

The added nan functions moved from core/numeric are:

    nanmean, nanvar, nanstd

TST: Added tests for nanmean(), nanvar(), nanstd()

2013-08-13T04:05:17+00:00

ENH: Adding np.nanmean(), np.nanstd(), np.nanvar()

2to3: Apply `print` fixer.

2013-04-06T19:25:26+00:00

Add `print_function` to all `from __future__ import ...` statements
and use the python3 print function syntax everywhere.

Closes #3078.

2to3: Use absolute imports.

2013-03-28T14:43:26+00:00

The new import `absolute_import` is added the `from __future__ import`
statement and The 2to3 `import` fixer is run to make the imports
compatible. There are several things that need to be dealt with to make
this work.

1) Files meant to be run as scripts run in a different environment than
files imported as part of a package, and so changes to those files need
to be skipped. The affected script files are:

    * all setup.py files
    * numpy/core/code_generators/generate_umath.py
    * numpy/core/code_generators/generate_numpy_api.py
    * numpy/core/code_generators/generate_ufunc_api.py

2) Some imported modules are not available as they are created during
the build process and consequently 2to3 is unable to handle them
correctly. Files that import those modules need a bit of extra work.
The affected files are:

    * core/__init__.py,
    * core/numeric.py,
    * core/_internal.py,
    * core/arrayprint.py,
    * core/fromnumeric.py,
    * numpy/__init__.py,
    * lib/npyio.py,
    * lib/function_base.py,
    * fft/fftpack.py,
    * random/__init__.py

Closes #3172

2to3: Replace xrange by range and use list(range(...)) where needed

2013-03-28T00:42:34+00:00

In python3 range is an iterator and `xrange` has been removed. This has
two consequence for code:

    1) Where a list is needed `list(range(...))` must be used.
    2) `xrange` must be replaced by `range`

Both of these changes also work in python2 and this patch makes both.

There are three places fixed that do not need it, but I left them in
so that the result would be `xrange` clean.

Closes #3092
