Downloaded Python 3.6 but terminal is still saying I'm using python 2.7.12
Open the text editor like nano , vim or gedit and open the .bashrc file ,
nano ~/.bashrc
and create the bash alias,
To do so add the following line into the .bashrc file:
alias python='/usr/bin/python3.6'
Save the file and re-open the terminal.
Edit:
Similarly, if you don't want to create the direct alias.
As @exprator suggested above you can also use python command for python 2 and python3 to use Python 3 version
I have looked for Python 2.7.12 in my apps and docs but I can't find it... 
I'm using a macbook pro.
I can see Python 3.6 in my applications so I don't know why the terminal isn't referring to this one.  
I want to get started learning django but I don't think it will be possible if I don't use Python 3.5 or later.  
is there a way to tell the terminal to use 3.6 instead?
