Parse error on input 'if' when trying to use a condition inside a do block

Question

I have the following code and I already tried multiple ways to write this, but I can\'t make it work. What I need is to use an if condition inside a do

Answer 1

You're missing an else.

palin :: IO ()
palin = do
  line <- getLine
  putStr line --Probably better to use putStrLn?
  if True then putStr line else putStr "hi" --Also consider putStrLn here?

You need to provide an value, if you're coming from Python, then think about something like

a = "dogs" if 1 < 0 else "cats" here, you need to provide the else as without it the variable assignment wouldn't run.
