How to use pyenv

I had this question after viewing Downgrading from Python 3.4.5 to 3.4.3.

Thanks for your response. If I install pyenv, are there any basic commands I need to know to make it work? The irony is that I'm trying to download and use a "learning to code" programme for a university course, so I don't have any experience with using the commands in python at all. I just need to know how to select Python 3.4.3 for one directory on my hard drive so that I can work through the python notebooks in that environment.
Thanks again.

Very detailed and thorough explanation of how to use pyenv. I will have to choose a moment when I have lots of time and get to grips with it properly.

P.S. I'm using a new mac. I don't know what Bash is though! I think I might be using it, as I've seen something about a bash profile before!

if you have a open console window. just type

echo $SHELL

Open in new window

The output should show you whether you'te using bash or another shell.

Thanks. the output was /bin/bash, so I guess that's what I'm using. I managed to load the python notebooks I needed by selecting all of the code within them, creating a new txt file, inserting it in there and saving it, then renaming the file .ipynb and opening. I guess it's not the orthodox way, but it seems to have worked.
Thanks for your help!
