TypeError: coercing to Unicode: need string or buffer, int found
提问by Marks Gniteckis
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:
我有 2 个 API。我正在从他们那里获取数据。我想将特定的代码部分分配给字符串，以便在编码时生活变得更轻松。这是代码：
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:
结果我得到：

The problem might have to do with the fact that you are adding ints to strings here
问题可能与您在此处向字符串添加整数有关
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,
据我所知，解释器不能将 int 隐式转换为字符串。不过，这可能有效，
str(name) + "'s interest receivable - " + str(closingStock)
On which I'm assuming Python > 3.0
我假设 Python > 3.0

You have to add '%s' % and () to each line, like this:
您必须在每一行中添加 '%s' % 和 ()，如下所示：
'%s' % (name + "'s interest payable - " + interestPayable)
