Hi All, How do I map a list to two lists with list comprehension?
For example, if I have x=[ [1,2], [3,4] ] What I want is a new list of list that has four sub-lists: [[1,2], [f(1), f(2)], [3,4], [f(3), f(4)]] [1,2] is mapped to [1,2] and [f(1), f(2)] and [3,4] is mapped to [3,4], [f(3), f(4)]. I just can't find any way to do that with list comprension. I ended up using a loop (untested code based on real code): l=[] for y in x: l.append(y) l.append([f(z) for z in y]) Thanks, Geoffrey -- http://mail.python.org/mailman/listinfo/python-list
