TypeError：__ init __（）在注释剥离程序中得到了一个意外的关键字参数'output'

Question

所以我的程序的基本目的是从C文件中取出注释并显示它们。

import urllib2
import html2text
import re
import subprocess
from cStringIO import StringIO

url = raw_input('Please input URL youd like to analyze: ')
page = urllib2.urlopen(url)
html_content = page.read().decode('utf8')
rendered_content =
html2text.html2text(html_content).encode('ascii','ignore')

f = open('file_text.txt', 'wb')
f.write(rendered_content)
f.close()

fd = open("file_text.txt", "r")
buf = fd.read()

def comment_remover(text):
    def replacer(match):
        s = match.group(0)
            if s.startswith('/'):
                return " "
            else:
                return s

    pattern = re.compile(
        #Stackoverflow- properly removes all comments
        r'//.*?$|/\*.*?\*/|\'(?:\\.|[^\\\'])*\'|"(?:\\.|[^\\"])*"',
        re.DOTALL | re.MULTILINE
    )
    return re.sub(pattern, replacer, text)

    input = StringIO(comment_remover(buf)) # source_code is a string with the source code.
    output = StringIO()

    process = subprocess.Popen(['sed', '/path/to/remccoms3.sed'], input=input, output=output)
    return_code = process.wait()

    stripped_code = output.getvalue()

这是我收到错误消息的地方：

from linecache import getline

with open("file_text.txt") as f:
    for ind, line in enumerate(f,1):
        if line.rstrip() == "---|---":
            print(getline(f.name, ind + 4))

基本上line.rstrip == '---|---'是在我运行程序时，该行是显示实际页面本身的注释的位置，而不是来自源的注释。
