# Build System Changes for Android.mk Writers
## Python 2 to 3 migration
The path set when running builds now makes the `python` executable point to python 3,
whereas on previous versions it pointed to python 2. If you still have python 2 scripts,
you can change the shebang line to use `python2` explicitly. This only applies for
scripts run directly from makefiles, or from soong genrules. This behavior can be
temporarily overridden by setting the `BUILD_BROKEN_PYTHON_IS_PYTHON2` environment
variable to `true`. It's only an environment variable and not a product config variable
because product config sometimes calls python code.
In addition, `python_*` soong modules no longer allow python 2. This can be temporarily
overridden by setting the `BUILD_BROKEN_USES_SOONG_PYTHON2_MODULES` product configuration
variable to `true`.
Python 2 is slated for complete removal in V.
