not able to execute python.3.5.1 on centos

Question

I installed python3.5.1 on CentOS

towards the end of the installation here is what I see

/bin/install -c -m 644 ./Include/weakrefobject.h /usr/local/include/python3.5m

To find the necessary bits, look in setup.py in detect_modules() for the module's name.

From what I understand python is installed successfully

But when I say # python3 or #python3.5 or #python3.5.1 (from root) it simply says

-bash: python3.5: command not found

I have not modified the installation path or anything so is installed on /usr/local...please see attached.

I followed the instructions at https://www.digitalocean.com/community/tutorials/how-to-set-up-python-2-7-6-and-3-3-3-on-centos-6-4

and had run the command

$make altinstall

should I be instead running ?

$make && make altinstall

*** update **** I tried out #make install instead of #make altinstall as recommended by @intboolstring and here is the output , in one of the screenshots you will see that is say "Python build finished successfully" but after this I am having no luck with running python3
