Preferred method for "Assignment by value"

Thank you both, the assigning using slicing works perfectly (as I'm
sure you knew it would)... It just didn't occur to me because it
seemed a little nonintuitive... The specific application was

def dicttolist (inputdict):
    for k, v in inputdict.iteritems():
        temp = v

    return finallist

to convert a dictionary to a list. We deal with large amounts of
bankdata which the dictionary is perfect for since loan number is a
perfect key... at the end, though, I have to throw it into a csv file
and the csv writer doesn't like dictionaries (since the key is an
iterable string it iterates over each value in the key)

by changing temp = v[:] the code worked perfectly (although changing
temp.insert(0,k) to temp = [k] + temp also worked fine... I didn't
like that as I knew it was a workaround)

Thanks again for the help
