atures of some language are a better solution than static typing. This is
of course more useful in languages that support both paradigms.

What static checking can actually guarantee varies depending on the
specific type system at hand (C# vs Haskell vs Idris for example). But most
of them can guarantee simple stuff like: "I'm I allowed to invoke this
function at this point?"
If you don't have that, well you can rely on tests to show

Hello,
In online forums sometimes people complain that they end up having to test
constantly for None, or that a function's argument has a specific type /
shape (which immediately brings the following aphorism to mind: "Any
sufficiently large test suite contains an ad hoc, bug-ridden, slow

Hello,
What do you guys think about adding a method "to_json" to dictionaries
and sequence types? Perhaps through a module import?

I use OpenInventor (Coin3d) which have a python binding called "pivy".
It works great.

All the benefits of Qt: multiplataform, excellent documentation, great

For the coding itself, I use netbeans + python plugin.

Hello,
Suppose this function is given:
def f(x,y):
return x+y+k
Is it possible to somehow assign a value to k without resorting to
making k global?
I'm thinking something like this:
eval("f(1,1)", {"f":f, "k":1})
Or even better, something like:
def g(k):
return f
g(1)(1,1) ==> 3

Finally installed Python 2.6, which is compiled with visual C++ 2008,
and all my problems went away.
Thanks to all,

Hello all,
I need to compile python myself because of a module (pivy). So I
downloaded MS Visual C++ 2008 express edition. It apparently compiled
fine but I don't know how to install it to recreate the standard
distribution. In linux i'd take "make install", but on windows?
Regards,
Juan Pablo
Thanks to all
I settled with this:
def partial1(f,b):
return lambda a:f(a,b)
def partial2(f,a):
return lambda b:f(a,b)

Hello!
given the definition
def f(a,b): return a+b
With this code:
fs = [ lambda x: f(x,o) for o in [0,1,2]]
or this
fs = []
for o in [0,1,2]:
fs.append( lambda x: f(x,o) )
I'd expect that fs contains partial evaluated functions, i.e.
fs[0](0) == 0
fs[1](0) == 1
fs[2](0) == 2
But this
27 matches
