Find Python 2 First
I would like you to find Python 2 first. We are only doing that to show you how to access Python 2 in your system. You will do almost the same steps to access version 3. You may also want to find out how access version 2.7 in future to work in this version. Do not delete the default version on your computer this will cause all types of problems since some of the Mac’s default software uses version 2.7 to run applications.
Step 1 – Access Your Terminal
We will be doing a lot work in terminal throughout this tutorial series so this is an important step. To access the terminal on a Mac you have several options.
Via Spotlight – We can find the terminal via the spotlight option on the Mac to do this push command + space bar at the same time or go to top of your screen and click on magnifying glass.
Now that we have the spotlight open now we simply type in “terminal”.
Simply hit enter and your terminal will open.
There you go there is your terminal. Your terminal may seem sort of different. That is all right as long as we got it open.
Via the finder – Now opening the terminal via the finder takes longer, but it’s good to know where it is located in your finder. Open finder > applications > Utilities > Terminal. There you go the terminal is open but easier to open via spotlight using command + space bar.
Optional Add Terminal to Dock – I add the terminal to the dock since I use it everyday this is optional for you, but if you are going to follow a long in this tutorial I suggest adding the terminal to your dock. To add the terminal to your dock right click terminal in the dock then go to options > click keep in dock.
Step 2 – Access Python 2
Now that we have the terminal open let’s access Python 2 we do this by simple typing “python” into the terminal and pressing the return key.
#Your layout may look different especially before the dollar sign
Thomass-MBP:~ Tommy$
#Now enter "python"
Thomass-MBP:~ Tommy$ python
#Hit enter
#Now you should see something similar to this
Python 2.7.6 (default, Sep 9 2014, 15:04:36)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

#If you see this then you have accessed Python Interpreter
If you did not get your Python 2 interpreter open then please let us know via the comments below or answers section in the main menu. We can look into why you were not able to access your Python 2 interpreter. Now that you were able to access the Python 2 interpreter lets exit the interpreter by typing quit() or exit() or control + d. When you exit your terminal should not show >>> that is how you know you have properly exited the interpreter.
Install Python 3 On Mac OS X
We can now install Python 3 on Mac OS X. Please follow the steps exactly, so we do not have any issues installing Python 3.
Step 1 – Visit http://python.org this is where we can download the Python 3 software.

Step 8 – When you press install a window will popup and ask you to enter your password please do so.
Step 9 – Python will start the install process.
Step 10 – When installation is complete press close button.
Now Python is installed on your computer. We will now check the installation to ensure that it installed properly. To check the installation of Python follow the next couple of steps.
Check Python 3 Installation
Step 1 – Open the terminal using the steps in the beginning of this tutorial.
Step 2 – Now we type “python3″ to open our Python 3 Interpreter and press Return.
Step 3 – We should see something very similar to the following screenshot.
If you see something very similar to the above screenshot especially Python 3.4.X. X being the latest version so this may change just a bit. If you see this, then you have successfully complete the Install Python 3 on Mac OS X tutorial. If you did not get this or got some errors please leave a comment below or in the answers section of this website so we can help you get Python 3 on your Mac.
