if i have list list1=[2,4,5,6,7,2,] how would i access values 4,5,6?
a = list1[1:4] print(a)
how would i access all the items in the list ?
by using the colon as the argument .
what function would i use to add an item to the end of the list?
append()
if i want to delete items from a list what do i use?
del
where does del go w.r.t. the list variable?
before the list variable
what is another was to remove item other that del?
the remove() function
show an example of how to use the remove function
list1.remove(5), where the item at index 5 is being removed.
what is a tuple?
