I'm on OSX, and I installed IDLE for Python 3.4. However, in Terminal my python -V and pip --version are both Python 2.7.
How do I fix this? I really have no idea how any of this works, so please bear with my lack of knowledge.

`python` is the system Python version. Are there `python3` and `python3.4` commands? – Martijn Pieters Apr 12 '15 at 01:12

You may just have to download and install a new python. – an earwig Apr 12 '15 at 01:12

@James_Parsons I downloaded IDLE for Python 3.4, as I said. I though I already had Python 3.4 installed. I can run scripts in it in IDLE. – Elle Nolan Apr 12 '15 at 01:16

How did you install IDLE? – an earwig Apr 12 '15 at 01:17

On the Python.org website, I went to the downloads page and clicked the "Install Python 3.4 Mac OSX" button. – Elle Nolan Apr 12 '15 at 01:18

The provided answer should work, but if you want to be able to just run `python` and run python 3, check this out: http://stackoverflow.com/questions/18425379/mac-set-default-python-version-to-3-3 – an earwig Apr 12 '15 at 01:22

Try python3 or python3.4. It should print out the right version if correctly installed.
Python 3.4 already has pip with it. You can use python3 -m pip to access pip. Or python3 -m ensurepip to make sure that it's correctly installed.

Okay, it does that. Now how do I update pip so that it installs things for Python 3 rather than Python 2? You didn't really answer my question... – Elle Nolan Apr 12 '15 at 01:17

@DrewNolan: Python 3.4 includes `pip`; you can use `python3.4 -m pip ...` to access the bundled version. – Martijn Pieters Apr 12 '15 at 01:29

When you install Python3, you can use python3 to run python programs(or use a shebang). Python 3 also install pip. If you find your Python3 installed version of pip try to alias the pip command to the newer pip. Check this out for more info:

I have found that making the 'python' alias replace the default version of python that the system comes with is a bad idea.
When you install a new version of python (3.4 for instance), these two new commands are installed, specifically for the version you installed:
pip3.4
python3.4
If you're using an IDE that wants you to indicate which python version you are using the IDE will let you navigate to it in the Library folder
pip will still be for python2.7 after you download some other python version, as I think that's the current version osx comes installed with
