Download Site for Python

I recently received an e-mail from a reader who had a bad install with Python 3.3.4 on a laptop with 64-bit Windows 7 installed. No matter what the reader did, the installation wouldn’t work. The application would fail with an error stating that pythonw.exe was unable to start and it included an error of 0xc000007b. He had downloaded the code from, which is the site mentioned on page 25 of Beginning Programming with Python For Dummies. However, downloading a copy from or did provide a copy of Python 3.4.3 (not the version 3.3.4 that is used in the book) that does work on his system.

The problem with this solution is that installing a copy from this second site also installs Anaconda—a product that isn’t covered in the book. In order to work with the IDLE examples in the book, you must open a copy of IDLE in the Anaconda\Scripts folder of the Anaconda installation. You’ll likely find this folder in your personal folder of your system. If you do find that you can’t get the copy of the product from the Python download site to work on your system, try this second solution and please let me know about the issue at I would strongly encourage you to try the setup found in the book, however, because using Anaconda will cause extra work for you and this book is truly meant to help someone who has little or no programming experience discover the joys of working with Python.

As a side note, I have tried the book’s source code with the latest Python release, 3.4.3 (the book was originally written to use version 3.3.4). All of the source code works on my test system, but I’d love to hear if it works on your system as well. You can obtain this updated version of Python at or (if you don’t mind installing Anaconda as well).

When using the 3.4.3 version of Python, your screenshots may vary some from those found in the book. All version-specific information will change, so you need to take this change into account as you read. Please let me know if you experience any problems using this updated version on your system. In the meantime, happy reading!
