| | 66 | * If you use anything from `urllib`, `urllib2`, `urlparse`, you will need to import the actual functions from `django.utils.py3`. |
| | 67 | You can grep the instances of those calls in the ported Django code to see how it's done. |
| | 68 | |
| | 69 | * If you're using `StringIO` or `BytesIO`, import them from `django.utils.py3`. |
| | 70 | |
| | 71 | * If a class has a `next()` method which is used for iteration, add a line `__next__ = next` just after it in the class. If it has |
| | 72 | a `__nonzero__` method, add `__bool__ = __nonzero` in the same way. Where you see `x.next()` used to iterate, do |
| | 73 | `from django.utils.py3 import next` and replace using the pattern `x.next()` -> `next(x)` (where `x` might be an expression |
| | 74 | rather than just a name). |

| | 76 | * If you define rich comparisons, review how they work in 2.x and 3.x and adapt your code accordingly. |
