The analog of the Python way of handling args among the C-style languages is
Java. So, no, you are on mission impossible :-)
class Mutable:
pass
v1 = Mutable()
v1.name = "v1"
v2 = "v2" #strings are immutable
def fun(a1, a2):
a1.name = "a1"
a2 = "a2"
fun(v1, v2)
print v1.name # prints a1
print v2 # prints v2
As a workaround, you can do:
def fun2():
a1 = Mutable()
a1.name = "A1"
return a1, "A2"
v1, v2 = fun2()
print v1.name # prints A1
print v2 # prints A2
See the tutorial (http://www.python.org/doc/current/tut/node6.html) for the
tricks you *can* do with function arguments
