Make sure you selected the Python 3.4 option, as Python 2.7 behaves differently and isn't what we use in this course. | |||

# Test your Python install at the command prompt. Type <pre>python</pre> and hit enter. You should see something like | |||

Python 3.4.2 (default, Oct 8 2014, 10:45:20) | |||

You just started Python! The <code>>>></code> indicates that you are at a new type of prompt: a Python prompt. The command prompt lets you navigate your computer and run programs, and the Python prompt lets you write and run Python code interactively. | |||

To exit the Python prompt, type <pre>exit()</pre> and press Enter. This will take you back to the Windows command prompt. | |||

You have Python installed and configured. | |||
== Alternate Install == | |||
Follow these instructions if the basic install fails for any reason: | |||
* Download and install the [http://continuum.io/downloads Anaconda] that includes Python 3.4: | |||
*# First, visit the [http://continuum.io/downloads Anaconda download page]. | |||
*# Click the blue text to the right side of the penguin logo that says "'''I WANT PYTHON 3.4'''". | |||
*# Click on top button on the right side of the same box under the text "'''CHOOSE YOUR INSTALLER'''". The button should say something like '''Windows 64-bit Python3.4 Graphical Installer'''. | |||
* Once the program is downloaded, run the downloaded file which should launch a graphical installer. | |||
* Use all of the defaults for installation, except make sure to '''check Make Anaconda the default Python'''. | |||
'''Note''' In addition to the 360MB file you will download, the installation will take several hundred megabytes for the 64-bit installer (which is most likely the version you'll be installing.) | |||
