Hey,
It's look simple for most of the people here but i can't figure out to 
that.

If i have :
def test():
    print "foo"
and:
var = "test"
how do i call function test from var, kind of ${$var} in some others 
languages (or eval())

There's always a way:
>>> def test():
...   print "hello"
...
>>> var = "test"
>>> eval("%s()" % var)
hello
But it depends how you are creating the reference to the function. The 
above is required if all you have is a string, but it would also be 
possible to set the variable to the function rather than the function's 
name:

>>> var = test
>>> var()
hello
>>>
Hope this helps.

 Steve
