the elementary functions are well-defined set, and i would include all of
them. that includes exp, sqrt, ln, trig, and hyperbolic functions.
i'll start a thread on python-ideas. thanks.

hi,
it would be really nice if elementary mathematical operations such as
sin/cosine (via __sin__ and __cos__) were available as base parts of the python
data model [0]. this would make it easier to write new math classes, and it
would eliminate the
Michael Gilbert added the comment:
i think that, for example, the default __rsub__ implementation could be:
return self + -other
which should just do the right thing assuming the addition and negation
functions already do the right thing for the class type.
anyway, any implementation
New submission from Michael Gilbert :
in order to make overrides simpler, and more obvious to average developers, it
would be very useful to automatically call the forward operations (e.g.
__mul__) when the reverse operations (e.g. __rmul__) are NotImplemented.
i spent quite a bit of time

hello, i've recently been working on some code where i am processing a
list, but excluding certain items. the solution is to use a list
comprehension in the for statement, which for example looks like:
for m in [n for n in range( 0 , 5 ) if n

Michael Gilbert added the comment:
ok, i see now. the list itself is changed in place, and the return value
of the remove() method is always None. since i din't assign the list to a
variable in the first place, there is hence no way now to access that
modified list.
thanks for your
New submission from Michael Gilbert :
using range in combination with remove is inconsistent. for example in
python 2.x:
>>> x = range(0,3)
>>> x.remove(1)
>>> x
[0, 2]
>>> x = range(0,3).remove(1)
>>> x
>>>
and in python 3.x:
