[Anaconda][Python] Update Python 2.x to 3.x with Anaconda

To upgrade to 3.x (for example 3.6). Create an environment with 3.6 is also suggested because the system settings are unchanged.

Use the command to create an environment named python36:

conda create --name python36 anaconda python=3.6

and then use the command "activate python36" to activate the environment :

activate python36

(Remarks: change text in orange to the environment name you used )
