[Numpy-discussion] eval shortcomings?

[Angus M. <am...@gm...>]

Hi all,

Can someone explain why the following occurs?

a = numpy.zeros((100))
b = numpy.ones((10))
a[20:30] = b                    # okay
eval('a[50:60] = b')         # raises SyntaxError: invalid syntax

Is there some line mangling that the interpretor does that eval doesn't do?

I see there's room for global and local parameters to eval. Would setting
one of those be the answer?

Cheers,

Angus.
