del is not a function, it is a statement, so it doesn't need the
brackets (parentheses for any Americans reading).
del unvisited_caves[0]
Although the parens don't do any harm.
To be clear, `del somelist[x]` deletes the xth item from somelist. But
`somelist.remove(x)` deletes the first item that equals x, equivalent to
this Python code:
for i in range(len(somelist)):
if somelist[i] == x:
del somelist[i]
break
