● 1st item in location 0

■ E.g whale = [5,4,7]
■ To access count=whales[0]+whales[1]+.....+ whales [13]
■ 5 is in location 0
● Need to be able to create a list
○ assgn_grades= [80,90,100,75,80]
○ List (range(0,5))
■ [0,1,2,3,4]
○ list(5) ‘int’ object is not (error)
○ pay_list= [0]*5
○ empty_lis=[]
○ #Ths works too
○ empty_List= list() have to create empty list and then add stuff to it
