"Python原始的HTML包含无法用替换命令去除的“\n”字符"

Question

我使用python get（url）命令获取HTML数据，该命令返回包含“\n”字符的原始HTML数据。当我对此运行replace（“\n”，”“）命令时，它不会删除它。有人能解释一下如何在“simple\u get”阶段或者从“raw\u htmlB”阶段删除它吗！代码如下。你知道吗

from CodeB import simple_get

htmlPath = "https://en.wikipedia.org/wiki/Terminalia_nigrovenulosa"        
raw_html = simple_get(htmlPath)
if raw_html is None:
    print("not found")
else:
    tmpHtml = str(raw_html)
    tmpHtmlB = tmpHtml.replace("\n","")    
    print("tmpHtmlB:=", tmpHtmlB)


from requests import get
from requests.exceptions import RequestException
from contextlib import closing
from bs4 import BeautifulSoup

def simple_get(url):
    try:
        with closing(get(url, stream=True)) as resp:
            if is_good_response(resp):
                return resp.content
            else:
                return None
    except RequestException as e:
        log_error('Error during requests to {0} : {1}'.format(url, str(e)))
        return None

def is_good_response(resp):
    content_type = resp.headers['Content-Type'].lower()
    return (resp.status_code == 200 
        and content_type is not None 
        and content_type.find('html') > -1)

def log_error(e):
    print(e)

Answer 1

我相信您需要在\n中添加另一个反作用“\”，以便搜索文本字符串\n并避免反作用。你知道吗

快速示例：

string = '\\n foo'
print(string.replace('\n', ''))

退货：

\n foo

而：

print(string.replace('\n', ''))

仅返回：

 foo

Answer 2

我认为在双引号之间加一个空格对你有好处

Answer 3

使用原始字符串r'\n或者记住\n代表换行符，您需要转义反斜杠：.replace('\\n', '')
