TypeError: coercing to Unicode: need string or buffer, int found

Question

I have 2 APIs. I am fetching data from them. I want to assign particular code parts to string so that life became easier while coding. Here is the code:

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 + "'s interest payable - " + interestPayable
        name + "'s interest receivable - " + interestReceivable
        name + "'s interest receivable - " + sales
        name + "'s interest receivable - " + expenses
        name + "'s interest receivable - " + openingStock
        name + "'s interest receivable - " + closingStock

print sum1

In result I get:

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

Answer 1

The problem might have to do with the fact that you are adding ints to strings here

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

As far as I’m aware, the interpretor cannot implicitly convert an int to a string.
This might work, though,

       str(name) + "'s interest receivable - " + str(closingStock)

On which I’m assuming Python > 3.0

You have to add ‘%s’ % and () to each line, like this:

'%s' % (name + "'s interest payable - " + interestPayable)
