Re: [pygame] Concerning copy

[Nelson <usenylon@xxxxxxxxx>]

Python's does pass by value, but the object is reference and if you modify it via a method it should be changed forever.

From http://www.poromenos.org/tutorials/python:

def func(arg):
    arg = ['another value']

value = ['original value']
func(value)
print value
['original value']

def func(arg):
    arg.append("value added by func")

value = ['original value']
func(value)
print value
['original value', 'value added by func']

Languages rarely have the ability to turn off "features" - akin to telling the English language not to have pronouns.
