Dictionary key and deque, dont work second popleft or first pop. python

Question

I am a begginer in python, i have a dictionary that has the key name and value as a deque, when i add in my deque it works, but when i try to withdraw with popleft only the first one works

from collections import deque

class EmployeePoint:

    dic = {}

    def __init__(self,name,point):

        self.name = name
        self.point = point


people1 = EmployeePoint("Rafael","18")
people2 = EmployeePoint("Rafael","19")
people3 = EmployeePoint("Rafael","20")

EmployeePoint.dic["Rafael"] = deque([people1])
EmployeePoint.dic["Rafael"].append([people2])
EmployeePoint.dic["Rafael"].append([people3])


print EmployeePoint.dic["Rafael"].popleft().point
print EmployeePoint.dic["Rafael"].popleft().point

Track back:

18 Traceback (most recent call last): File "main.py", line 23, in print EmployeePoint.dic["Rafael"].popleft().point AttributeError: 'list' object has no attribute 'point'

Answer 1

Initializing the deque is fine with deque([people1]) but you shouldn't be appending a list with one item in it (i.e. [people2] instead .append(people2)

from collections import deque

class EmployeePoint:

    dic = {}

    def __init__(self,name,point):

        self.name = name
        self.point = point


people1 = EmployeePoint("Rafael","18")
people2 = EmployeePoint("Rafael","19")
people3 = EmployeePoint("Rafael","20")

EmployeePoint.dic["Rafael"] = deque([people1])
EmployeePoint.dic["Rafael"].append(people2)
EmployeePoint.dic["Rafael"].append(people3)


print (EmployeePoint.dic["Rafael"].popleft().point)
print (EmployeePoint.dic["Rafael"].popleft().point) 
# py3 print paretheses 

Output:

18

19
