Arguments and returnings

Question

I need to know if we can modify the variable that I give to function, like this:
i=0
function(i)
print(i)

and the output is something else.
There's a way to do that?

Answer 1

You could have the function return the new value, and then reassign the variable with it. Ex:

def function(x)
#Your code
return x

i = 0
i = function(i)
print(i)

Answer 2

No, Python doesn't have means of passing basic/primitive types (int, string, etc) by reference. Although it's not the best practice, returning a list of values you want and picking them apart afterward is a workaround.

Answer 3

That is a possible solution but in c++ we can use pointers and in python we can do something like it?
