How can I create priority queue that contains my class implementation?

Question

I got task class that I implemented, I want to insert all my tasks into priority queue, there is one in python? Do I need to implement some func inside my class to make it comparable?

Each class got priority number.

Answer 1

There is indeed a priority queue in Python, see here: https://docs.python.org/3/library/queue.html#Queue.PriorityQueue

Here is a simple example:

from queue import PriorityQueue

q = PriorityQueue()

q.put((2, 'code'))
q.put((1, 'eat'))
q.put((3, 'sleep'))

while not q.empty():
    next_item = q.get()
    print(next_item)

# Result:
#   (1, 'eat')
#   (2, 'code')
#   (3, 'sleep')

You can also use heapq as well.

Can't comment on your implementation without knowing more information...
