我有:
stuff :: IO [String]
doThings :: String -> IO [()]
我想要
stuff >>= doThings
但我的类型已关闭。我想基本上做一个提升的绑定,但我尝试的一切都是巧妙的错误。

使用原始类型,您可以:
import numpy as np
from sklearn.feature_extraction.text import CountVectorizer
def wordcount(data):
cv = CountVectorizer(min_df=0, strip_accents="ascii", decode_error ="ignore")
counts = cv.fit_transform([data]).toarray().ravel()
words = np.array(cv.get_feature_names())
counts = map(int, counts)
words = [i.tolist() for i in words]
words = [x.encode('UTF8') for x in words]
unsorted_result = zip(words, counts)
print sorted(unsorted_result,key=lambda x: x[1], reverse=True)
如果您将doThings更改为类型stuff >>= mapM_ doThings

如果你有很多这样的功能,这是ListT
的教科书用例:
Sub RunCmd
dim shell
dim shellWithLog
dim command
dim ARGS
set shell = createobject("Shell.Application")
set shellWithLog = createobject("wscript.shell")
command = "gui.cmd"
if (checkbox1.checked) then
ARGS = ARGS + " Do_This"
end if
if (checkbox2.checked) then
ARGS = ARGS + " Do_That"
end if
if (logFile.checked) then
shellWithLog.run (shell.shellExecute command, ARGS), " &>" + "publishLog.log", 1
else
shell.shellExecute command, , "runas", 1
end if
End Sub
