integer_name = 4 # integer
float_name = 3.0 # float
list_name = ['a','b','cats','dogs', 1, 2.0] # list
list_name.append(3) # add to list
# list comprehension filters for int types from the previous list
list_comp = [x for x in list_name if type(x) is int]
# dictionary
dic = {"Bob":9766692343,"Alice":6123336678}
dic["Alice"] # returns 6123336678
dic_phone_numbers = dic.values() # returns list of values
dic_names = dic.keys() # returns list of keys
# class (cat object with 9 lives)
class Cat:
  def __init__(self,name):
    self.name = name
    self.lives = 9
