Software installation instructions for Fajitas and Finance workshop with Winton Capital

The software that will be used in the workshop is python 2.7 (and a few other python packages), so in order to follow along on your laptop, you will need to install this software. Luckily, this is a straightforward process that requires two steps. The first step involves downloading and installing the software, while the second step is to run a test program to see if installation was successful. Please try to install and test the software before coming to the workshop. If you are unable to do so, then please arrive at 5:30 pm and somebody from the SIAM committee will be there to assist you with this.

The easiest way to install python and the extra packages is using the free version of the Enthought Python Distribution (EPD Free). To access the files that you need to download, please to go this page

and fill in your name/email. After you've done this, you will be directed to another page with Mac/Windows/Linux installers you'll also find brief instructions on how to run the downloaded file.

Note for Linux users: you might find it easier to install python 2.7 and the extra packages (numpy, scipy, matplotlib) using a package manager.

The installation can be tested by running a test file that can be downloaded. Running the test file will require a few simple steps:

1. Open a command window
- Windows: find the program called Command Prompt in the Start Menu and open it.
- Mac: type Terminal in the Spotlight and open it
- Linux: find Terminal in the panel and open it.

2. Determine the folder the command window is pointing to
- Windows: type "cd" (without quotation marks) in the command window and press enter
- Mac/Linux: type "pwd" (without the quotation marks) in the command window and press enter
The name of a folder should appear in the window. 

3. Download the test file ( and save it in the folder that appeared in the command window in step 2.
- The test file can be downloaded at

4. Run this program by typing "python" (without the quotation marks) in the command window. If successful, the output should read:

Today is: 2012-01-27 13:46:25.935534 (this line will be different when you run the code)
Latest Women's 100m record is: 10.49
Record set, 1988-07-16 00:00:00
test sum maths: True
All tests good!

There should now be an image called 100time.png in the folder where you saved the file too.
