The following is the list that I have:

```
>>> issue_search
[<JIRA Issue: key=u'NEC-1519', id=u'991356'>, <JIRA Issue: key=u'NEC-1516', id=u'991344'>, <JIRA Issue: key=u'NEC-1518', id=u'990463'>]
>>>

```

I was using the following:

```
issue_string = ','.join(map(str, issue_search))

```

But the output is:

```
NEC-1519, NEC-1516, NEC-1518

```

I am confused on the output. How is only the `key` getting displayed? How to get the other text too in the string format?
