replicate n x is a list of length n with x the value of every element. It is an instance of the more general genericReplicate, in which n may be of any integral type.

>>> replicate 0 True
[]

>>> replicate (-1) True
[]

>>> replicate 4 True
[True,True,True,True]

replicateM n act performs the action act n times, and then returns the list of results:

Examples

>>> import Control.Monad.State

>>> runState (replicateM 3 $ state $ \s -> (s, s + 1)) 1
([1,2,3],4)

Like replicateM, but discards the result.

Examples

>>> replicateM_ 3 (putStrLn "a")
a
a
a
