Use a nested list comprehension, for example Prelude> [['a'| i <- [0..n]]++"\n"|n <- [1..3]] ["aa\n","aaa\n","aaaa\n"]

What are the limitations of list comprehension. I want to use listcomprehension to output the pattern below. So a mixture of a's and newline characters. The part im stuck at is creating arguments in thelistcomprehension to stop at some point then execute next loop. Is it even possible to create the pattern below purely from list comprehension.Thankyouin advance. a aa aaa --View this message in context: http://www.nabble.com/Query-on-list- comprehension-tp22573574p22573574.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com._______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
