I have made a function by scraping a page and I run but the output gives \r\n. I used strip function to remove \r\n but its not working. Why and how to remove \r\n? Here is the link: https://ibb.co/VtVV2fb

import scrapy
from .. items import FetchingItem

class SiteFetching(scrapy.Spider):
    name = 'Site'
    start_urls = ['https://www.rev.com/freelancers']
    transcription_page = 'https://www.rev.com/freelancers/transcription'

    def parse(self, response):
        items = {
            'Heading': response.css('#sign-up::text').extract(),
            'Earn_steps': response.css('.pb2 .lh-copy::text , .mb1::text , .mb3 .lh-copy::text').extract(), 
    }

        yield response.follow(self.transcription_page, self.trans_faqs, meta={'items':items})

    def trans_faqs(self, response):
        items = response.meta['items']
        names = {
            'name1': 'FAQ1',
            'name2': 'FAQ2', 
        }
        finder = {
            'find1': '#whatentailed p::text , #whatentailed .mr3::text',
            'find2': '#requirements p::text , #requirements .mr3::text'
        }
        for name, find in zip(names.values(), finder.values()):
            items[name] = list(map(str.strip,response.css(find).extract()))
        yield items

推荐答案

每当我有一个带有制表符或换行符的字符串时，我发现用 '' 替换它们对我很有效.

Whenever I have a string with tabs or newlines, I found that replacing them with '' works for me.

例如，如果你的字符串变量中有 \t 和 \n，你可以这样做:

For example, if you have both \t and \n in your string variable, you could do this:

string_variable.replace('\n','').replace('\t','')

到目前为止效果很好.
