TypeError: принуждение к Unicode: нужна строка или буфер, int found

У меня есть 2 API. Я извлекаю данные из них. Я хочу назначить конкретные части кода для строки, чтобы жизнь стала проще при кодировании. Вот код:

import urllib2
import json

urlIncomeStatement = 'http://dev.c0l.in:8888'
apiIncomeStatement = urllib2.urlopen(urlIncomeStatement)
dataIncomeStatement = json.load(apiIncomeStatement)

urlFinancialPosition = 'http://dev.c0l.in:9999'
apiFinancialPosition = urllib2.urlopen(urlFinancialPosition)
dataFinancialPositiont = json.load(apiFinancialPosition)

for item in dataIncomeStatement:
    name = item['company']['name']
    interestPayable = int(item['company']['interest_payable'])
    interestReceivable = int(item['company']['interest_receivable'])
    sales = int(item['company']['interest_receivable'])
    expenses = int(item['company']['expenses'])
    openingStock = int(item['company']['opening_stock'])
    closingStock = int(item['company']['closing_stock'])
    sum1 = sales + expenses

    if item['sector'] == 'technology':
        name + " interest payable - " + interestPayable
        name + " interest receivable - " + interestReceivable
        name + " interest receivable - " + sales
        name + " interest receivable - " + expenses
        name + " interest receivable - " + openingStock
        name + " interest receivable - " + closingStock

print sum1

В результате я получаю:

Traceback (most recent call last):
  File "C:/Users/gnite_000/Desktop/test.py", line 25, in <module>
    name + " interest payable - " + interestPayable
