Why am I getting an error message in Python 'cannot import name NoneType'?

Question

I'm trying to convert some code from 2 to 3 and the following simple script ``` import types from types import NoneType ``` Results in ImportError: cannot import name NoneType How can I convert the above from 2 to 3?

Accepted Answer

There is no longer a `NoneType` reference in the `types` modules. You should just check for identity with `None` directly, i.e. `obj is None`. An alternative way, if you really need the `NoneType`, would be to get it using:

```
NoneType = type(None)
```

This is actually the exact same way `types.NoneType` was previously defined, before it was removed on November 28th, 2007.

As a side note, you do not need to import a module to be able to use the `from .. import` syntax, so you can drop your `import types` line if you don’t use the module reference anywhere else.
