 Applications that are compatible with Python 2 **should** use the Apple-provided system Python in `/usr/bin` on systems that provide Python 2.7. To do this, declare:
 
 ```ruby
-depends_on :python if MacOS.version <= :snow_leopard

 ```
 
-No explicit Python dependency is needed on recent OS versions since `/usr/bin` is always in `PATH` for Homebrew formulae; on Leopard and older, the python in `PATH` is used if it's at least version 2.7, or else Homebrew's python is installed.

 ## Bindings

-Python 2 libraries do not need a `depends_on :python` declaration; they will be built with system Python, but should still be usable with any other Python 2.7. If this is not the case, it is an upstream bug; [here is some advice for resolving it](http://blog.tim-smith.us/2015/09/python-extension-modules-os-x/). Libraries built for Python 3 should include `depends_on :python3`, which will bottle against Homebrew's python3, and use the first python3 discovered in `PATH` at build time when installing from source with `brew install --build-from-source`. If a library supports both Python 2.x and Python 3.x, the `:python3` dependency should be `:optional`. Python 2.x libraries must function when they are installed against either the system Python or Homebrew Python.
