Review comment:
One way to determine this is to look at the download data from pypi and see
which versions of python people are using when they install this library. The
results for the past 30 days are the following:
```
[
{
"python_version": "3.5",
"download_count": "30258"
},
{
"python_version": "3.6",
"download_count": "26228"
},
{
"python_version": "3.4",
"download_count": "9140"
},
{
"python_version": "3.7",
"download_count": "2502"
},
{
"python_version": null,
"download_count": "793"
},
{
"python_version": "2.7",
"download_count": "173"
},
{
"python_version": "2.6",
"download_count": "3"
}
]
```
So it seems it is used commonly on 3.5+ and there is some use on 3.4.

> egg_info fails for avro-python3 using python2
> ---------------------------------------------
>
> Key: AVRO-2240
> URL: https://issues.apache.org/jira/browse/AVRO-2240
> Project: Avro
> Issue Type: Bug
> Components: python
> Affects Versions: 1.8.2
> Reporter: Luke Zulauf
> Priority: Major
>
> When managing dependencies, the ability to call egg_info on any package is
> especially useful (even if the package is not valid for installation with a
> specific python version).
> For example, pipenv can't build a lockfile in python2 if avro-python3 is
> listed as a dependency (for any python version)
>
> The opposite works (using python3 to check the egg_info of avro (the python2
> version).
>
> {code:java}
> $ python3 avro/setup.py egg_info
> (succeeds)
> $ python2 avro/setup.py egg_info
> (succeeds)
> $ python3 avro-python3/setup.py egg_info
> (succeeds)
> $ python2 avro-python3/setup.py egg_info
> (fails){code}
> It would be great if you didn't raise an assertion error for all usages of
> running setup.py, especially when running egg_info.
