[Haskell-beginners] Loop

[Sumit Sahrawat, Maths & Computing, IIT (BHU)]

The reply I gave before might be more helpful if you consider the fact that

    a >> b >> c

is equivalent to

    do a
       b
       c

You can then use

    forM_ [1..4] (\_ -> putStrLn "Test")

What this does is,

    1. map (\_ -> putStrLn "Test") on [1..4]
    2. Use sequence_ to combine those operations

The even shorter way is replicateM_ which works like replicate from
Data.List
