Instruction
Good. If you want to delete an element from a list, there are a few ways to do so. Use the del operator if you know the index.
# define a list companies = ['Royal Dutch Shell', 'BP', 'Total', 'Volkswagen', 'Glencore Xstrata', 'Gazprom'] # delete Total del companies[2]
When you delete companies[2], the next element (companies[3], which is Volkswagen) takes its place, and all elements with higher indices are shifted so that there are no empty spaces in your list. This is an important concept: deleting an item can change multiple indices in your list.
Exercise
Get rid of the very first element in the water_level list.
Stuck? Here's a hint!
The first element has an index of 0.
