Years ago, my daughter was 7 years old. She was precocious like I had been when I was little. I sat down with her in front of the python REPL, and showed her how to use it. She immediately understood what a variable was. A few days later she wanted to add up a few prices, and she fired up a python window, and got a floating point representation problem in the result. This put her off programming for life. She has never since wanted anything to do with it.
