+For Python.3.7, python.org currently provides two installer variants for download: one that installs a 
+\i 64-bit/32-bit Intel
+\i0  Python capable of running on 
+\i macOS 10.6 (Snow Leopard)
+\i0  or later; and one that installs a

+\i0 Python capable of running on 
+\i macOS 10.9 (Mavericks)
+\i0  or later.  This ReadMe was installed with the 
+\i $MACOSX_DEPLOYMENT_TARGET
+\i0  variant.  Use the 10.6 variant if you are running on macOS 10.6 through 10.8 or if you want to produce standalone applications that can run on systems from 10.6.  If you are running on macOS 10.9 or later and if you have no need for compatibility with older systems, use the 10.9 variant.  The Pythons installed by these installers are built with private copies of some third-party libraries not included with or newer than those in macOS itself.  The list of these libraries varies by installer variant and is included at the end of the License.rtf file.
