Hi, I need help for a task looks very simple:
I got a python list like: [['a', 'b'], ['c', 'd'], ['e', 'f'], ['a', 'g'], ['e', 'k'], ['c', 'u'], ['b', 'p']] Each item in the list need to be merged. For example, 'a', 'b' will be merged, 'c', 'd' will be merged. Also if the node in the list share the same name, all these nodes need be merged. For example, ['a', 'b'], ['a', 'g'] ['b', 'p'] will be merged to ['a', 'b', 'g', 'p'] The answer should be: [['a', 'b', 'g', 'p'], ['c', 'd', 'u'], ['e', 'f', 'k']] Anyone has a solution? Thanks, JD -- http://mail.python.org/mailman/listinfo/python-list
