Python help thread?

Simple enough question:

I have two lists. I want to the 2nd one to be a sorted list of the 1st one while keeping the original as it is. Is there a function I can use or would I actually have to separately program it and manually make a new list?

Example of what I don't want happening:

Code:

c = [1,5,6,3,2,10]
c_sorted = c
c_sorted.sort()

print c
print c_sorted

They come out as both being sorted. I'm not quite understanding what's going on here.
