# Porting to Python 3
This is still a proposal at this stage.
## Motivation
* Make code behave the same on Python 2 and Python 3, insofar as one can, so e.g. `map()` is the same on Python 2 and Python 3 (i.e. lazy).
@ -12,7 +10,7 @@ This is still a proposal at this stage.
TBD, something involving core abstractions first, then dependency graph topological traversal.
Assume for now we've picked a module.
At the moment we're focusing on just porting `allmydata.util`, since it's necessary for other packages.
## The porting process, big picture
@ -72,4 +70,8 @@ In particular:
* `map()`, `filter()`, etc. are now lazy.
* `dict.keys()` and friends now return a view of the underlying data, rather than a list with a copy.
**Fifth**, add a note to the module docstring saying it was ported to Python 3.

### Other notes
If you just want to run the tests from the explicitly ported test modules, you can do `python -m allmydata.util._python3`.
