I'm creating a blockchain in Python using Flask but now get an error when I try to make the HTTP requests to mine. Current full code is at https://github.com/MGedney1/Python-Blockchain/blob/master/blockchain.py . The error I am getting is

TypeError 'dict' object not callable.

Relevant code:

from hashlib import sha256      #Imports
import json
from time import time
from textwrap import dedent
from uuid import uuid4
from flask import Flask, jsonify, request
class Blockchain(object):
    def __init__(self):     #Initialising the blockchain
        self.chain = []     
        self.transactions_list = []      
        self.add_block(proof=100,previous_hash=1)       #Genesis block
    def add_block(self, proof, previous_hash=None):
        Creates a new block and adds it to the chain
        Parameters:
            proof (int): The proof given by the Proof of Work algorithm
            previous_hash (str): The hash of the previous block
        Returns:

        Returns:

        return last_block

Your end_block method is decorated as a property. That means you should omit the parentheses when accessing it, e.g.
last_block = blockchain.end_block  # Parentheses omitted
By including the parentheses you are taking the thing end_block returns (last_block) and trying to call it as a function, just like if you did last_block().
Alternatively, remove the @property decorator from end_block.
