A link from http://docs.python.org/library/stdtypes.html#set.union to http://en.wikipedia.org/wiki/Union_%28set_theory%29 would help young people to understand sets. Of course it is the same for intersection(), difference(), and symmetric_difference(). The images of the wikipedia article explain it very good. |

Only for relatively uncommon concepts like "Moving Average" and some other cases used in collections module hyperlink to a general article helps. Set theory is a commonly understood concept and link to wikipedia article may not be required. It can be left to the user to find out more, if they want. |

There is no end of helpful articles at Wikipedia and elsewhere. Wikipedia articles are especially easy to find with a special search in some browsers and on the site. In my experience on python-list, for instance, people have much more problem with floats, for instance, than sets. Certainly, sets are taught much better in U.S. schools. |

I concur with the other respondants. Also, experience has shown a near zero learning curve for sets. For whatever reason, people seem to just get it and not require further explanation. |
