Introduction
List basics
Lists with if statements and loops
Lists in functions
Instruction
Well done! We can also use the concatenation operator (+) to combine two lists.
# define a list companies = ['Royal Dutch Shell', 'BP', 'Total', 'Volkswagen', 'Glencore Xstrata', 'Gazprom'] # define another list new_companies = ['E.ON', 'Eni', 'ING'] # add new_companies to the old list companies = companies + new_companies
As you can see, we created a new list named new_companies and then added its contents to the end of the companies list. At this point, companies has the following items:
['Royal Dutch Shell', 'BP', 'Total', 'Volkswagen', 'Glencore Xstrata', 'Gazprom', 'E.ON', 'Eni', 'ING']
Exercise
Add three consecutive days using a single instruction. The water levels on days 8 through 10 were 772 cm, 770 cm, and 745 cm, respectively. Then, print the whole list.
Stuck? Here's a hint!
You can create a new list with the following three elements: [772, 770, 745]. Add both lists using +.
