1) If you are naming your list "list," you're asking for trouble. Shadowing builtin names is risky. Ten years ago I named a variable "max". Oops.
2) list.remove() operates in-place. Would you expect it to return a copy? Making that copy could potentially use a lot of memory and time.
3) If you do want a copy, construct it from two slices of your original list. Let's say the element you want to remove is at position 6. Then:
new_list = old_list[:6] + old_list[7:]
3)
