Passing by value instead of reference

[Janko Hauser]

Frederic says no :-)

But in case of mutable arguments one can use sometimes (if one knows
the type of the arguments beforehand) copy.copy() or copy.deepcopy(),
or not?


import copy

def byvalue(a):
    a=copy.deepcopy(a)
    a[3]=10

a=[1,2,3,4]
print a
byvalue(a)
print a

This is not general, but helps in some situations.
