Haskell的錯誤 - 語法錯誤「=」

Question

我編譯此代碼，receving的「輸入解析錯誤‘=’'錯誤

import System.IO 
import Data.List.Split 
main = do 
    handle <- openFile "ac/abc" ReadMode 
    contents <- hGetContents handle 
    let xs = splitOneOf "; \n " contents  
    print xs 
    readStrList contents = do 
     print contents 
    hClose handle 

請建議什麼是錯的

Answer 1

問題在這些線路：

readStrList contents = do 
    print contents 

如果你試圖定義readStrList，那麼你需要把let在面前：

let readStrList contents = do 
     print contents
