python - 在 "lines.replace"之后删除\n

Question

用“conv:”后的空格执行脚本，结果是一个“换行符”，如下所示:

    lines = lines.replace("www.","conv: ")

conv:
yahoo.com
conv:
yahoo.it
conv:
yahoo.org
conv:
yahoo.net

如何删除\n(新行)？

conv 后删除空格字符:脚本运行完美。

#!/usr/bin/python

with open('/home/user/tmp/prefix.txt') as f:
    lines = f.read()
    lines = lines.replace("http://","")
    lines = lines.replace("www.","conv:")

    urls = [url.split('/')[0] for url in lines.split()]
    print ('\n'.join(urls))

结果是:

conv:yahoo.com
conv:yahoo.it
conv:yahoo.org
conv:yahoo.net

我想要:

conv: yahoo.com
conv: yahoo.it
conv: yahoo.org
conv: yahoo.net

Answer 1

线

urls = [url.split('/')[0] for url in lines.split()]

在空格上拆分您的行，因此您将获得 conv: 部分作为单个 url。

你可以做

urls = [url.split('/')[0].replace("conv:", "conv: ") for url in lines.split()]

相反。
