Can't access individual agents in group with index

[juliazhang95]

In the documentation, it says that individual agents in a group can be accessed with an index. When I tried this, it gave me a TypeError

Code used:

# Define all agents in the economy
class Citizen(abce.Agent):    
    def init(self, money):        
        # initial money balance
        self.create('money', money)

        # years of schooling
        self.employee_qualification = random.randint(0, 21)

        def get_salary():
            return 100

simulation = abce.Simulation(name='economy', processes=1)    
citizens = simulation.build_agents(Citizen, 'citizen', number=num_citizens, money = 1000)

citizens[0].get_salary()

Error:

     61                     ret = self.agents[group][i]._execute(command, args, kwargs)

TypeError: 'int' object is not iterable

Please let me know if I am attempting to access the agents incorrectly, or doing something wrong!

Dear Julia, we have fixed this bug. Please run pip install abce --upgrade

Yes, the bug is no longer in master. I ran a slightly modified version of the code above, and encountered no problem

import random
import abcEconomics as abce

# Define all agents in the economy
class Citizen(abce.Agent):    
    def init(self, money):        
        # initial money balance
        self.create('money', money)

        # years of schooling
        self.employee_qualification = random.randint(0, 21)

    def get_salary(self):
        return 100

simulation = abce.Simulation(name='economy', processes=1)    
citizens = simulation.build_agents(Citizen, 'citizen', number=10, money = 1000)

print(citizens[0].get_salary())
