excuse me, I have a question is Haskell programming and I need someone help me to solve it
 
I have a list of strings, I want to use putStr in Data.Char to show it out in the terminal screen. For example, a string likes ["!@#$","#@$"] will be shown as
 
"!@#$"
 
"#@$"
 
Actually, I don't know the good way the make it. Please help me {{unsigned|Cgo}}
 
 
:The best place for your question is something like the haskell-beginners mailing list or really, just the #haskell IRC channel.
 
:There are several approaches you could take. Some combination of `map`, `putStr`, `mapM`, `print`, and `++` would work. As specified, you want `mapM print`:
 
 
Prelude> mapM print ["!@#$","#@$"]
 
"!@#$"
 
"#@$"
 
 
:I also strongly urge you to read [[Homework help]] & http://www.catb.org/~esr/faqs/smart-questions.html . --[[User:Gwern|Gwern]] 20:26, 23 November 2010 (UTC)
