我有一个包含以下功能的模块文件：
def replace(filename):
match = re.sub(r'[^\s^\w]risk', 'risk', filename)
return match
def count_words(newstring):
from collections import defaultdict
word_dict=defaultdict(int)
for line in newstring:
words=line.lower().split()
for word in words:
word_dict[word]+=1
for word in word_dict:
if'risk'==word:
return word, word_dict[word]
当我在 IDLE 中执行此操作时：
>>> mylist = open('C:\\Users\\ahn_133\\Desktop\\Python Project\\test10.txt').read()
>>> newstrings=replace(mylist)
>>> newone=count_words(newstrings)
test10.txt 仅包含用于测试的单词，例如：
#风险风险更大的风险。风险？
#我收到以下错误：
Traceback (most recent call last):
File "<pyshell#134>", line 1, in <module>
newPH = replace(newPassage)
File "C:\Users\ahn_133\Desktop\Python Project\text_modules.py", line 56, in replace
match = re.sub(r'[^\s^\w]risk', 'risk', filename)
File "C:\Python27\lib\re.py", line 151, in sub
return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or buffer
无论如何运行这两个函数而不保存newstrings到文件中，使用打开它readlines()，然后运行count_words函数？
