无法处理列表python 3.5中http-文本文件的行

Question

url="https://www.sec.gov/Archives/edgar/data/3662/0000950170-98-000413.txt"
data=urllib.request.urlopen(url)

list_line=[str(x) for x in data]

for line in list_line:
    line.replace("b'","")
    line.replace("\\n","")
    line.replace("\\t","")
print (list_line)

它生成的列表如下：

“b”-开始隐私增强消息"b‘V5559QRyTgPe9PfVt0db9Q==\n'“、"b'\n'”、"b'0000950170-98-000413.txt :19980309\n“、"b'0000950170-98-000413.hdr.sgml : 19980309\n'”<-样本

我想删除b'，\n和\t，字符串拆分和替换无效，怎么做呢？

Answer 1

与其试图替换东西，不如将数据解码为utf-8，以获得结果文本：

import urllib.request

url = "https://www.sec.gov/Archives/edgar/data/3662/0000950170-98-000413.txt"
data = urllib.request.urlopen(url).read()
text = data.decode('utf-8')
text = text.replace('\t', '')   # Remove tabs if still needed
print(text)

这将显示案文的开头如下：

如果您想要一行列表，请添加：

lines = text.splitlines()
