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] = response.css(find.strip()).extract()
    yield items

推荐答案

strip() 只能去掉字符串末尾的\r\n，不能去掉里面.如果你在文本中有 \r\n 然后使用 text = text.replace(\r\n', '')

strip() can remove \r\n only at the end of string, but not inside. If you have \r\n inside text then use text = text.replace(\r\n', '')

似乎你在 extract() 创建的列表中得到 \r\n 所以你必须使用列表理解从列表中的每个元素中删除

it seems you get \r\n in list created by extract() so you have to use list comprehension to remove from every element on list

data = response.css(find).extract()
data = [x.replace('\r\n', '').strip() for x in data]
items[name] = data

删除句子之间的空格和 \r\n 你可以 split('\r\n') 来创建列表用句子.然后你可以strip()每一句话.并且你可以' '.join()把所有的句子都恢复成一个字符串.

to remove spaces and \r\n between sentences you can split('\r\n') to create list with sentences. then you can strip() every sentence. And you can ' '.join() all sentences back to one string.

text = 'Sentence 1\r\n    Sentence 2'

data = text.split('\r\n')
data = [x.strip() for x in data]
text = ' '.join(data)

print(text)

同一行

text = 'Sentence 1\r\n    Sentence 2'

text = ' '.join(x.strip() for x in text.split('\r\n'))

print(text)

同re

import re

text = 'Sentence 1\r\n    Sentence 2'

text = re.sub('\r\n\s+', ' ', text)

print(text)

<小时>

for name, find in zip(names.values(), finder.values()):
    data = response.css(find.strip()).extract()
    data = [re.sub('\r\n\s+', ' ', text) for text in data]
    items[name] = data
