如何将列表项换行符拆分为 python 中的逗号

Question

我用过这个

print(listing_jobs)

导致了这个

['Senior Cloud Specialist\nFull-time · Singapore · 5 - 10 Years\n12 days ago', 'Cloud Native Developer\nFull-time · Hyderabad · 2 - 5 Years\n13 days ago']

如何将 \n 转换为逗号？

当我使用

listing_jobs.strip().split('\n')

显示错误

AttributeError: 'list' object has no attribute 'strip'

Answer 1

如果我很好地理解您的问题，您想将列表 listing_jobs 的元素拆分为 \n 吗？如果是这样，您可以按如下方式使用列表理解：

d = ['Senior Cloud Specialist\nFull-time · Singapore · 5 - 10 Years\n12 days ago',
 'Cloud Native Developer\nFull-time · Hyderabad · 2 - 5 Years\n13 days ago']
d = [x.strip().split("\n") for x in d]

这将给出以下列表列表：

[['Senior Cloud Specialist',
  'Full-time . Singapore . 5 - 10 Years',
  '12 days ago'],
 ['Cloud Native Developer',
  'Full-time . Hyderabad . 2 - 5 Years',
  '13 days ago']]

但是你最终会得到一个列表列表。如果要将其展平为字符串列表，请执行以下操作：

result = []
for el in d:
     result = result + el

输出：

['Senior Cloud Specialist',
 'Full-time . Singapore . 5 - 10 Years',
 '12 days ago',
 'Cloud Native Developer',
 'Full-time . Hyderabad . 2 - 5 Years',
 '13 days ago']

总代码：

# original data
d = ['Senior Cloud Specialist\nFull-time · Singapore · 5 - 10 Years\n12 days ago',
 'Cloud Native Developer\nFull-time · Hyderabad · 2 - 5 Years\n13 days ago']
# split by "\n"
d = [x.strip().split("\n") for x in d]
# flatten the list of lists into a list of strings
result = []
for el in d:
     result = result + el

为什么会出现以下错误？

"AttributeError: 'list' object has no attribute 'strip'"

因为 strip 可以应用于 str（字符串）类型，并且您正在将其应用于列表。

Answer 2

您需要遍历字符串列表，并将 \n 替换为 ,

listing_jobs = ['Senior Cloud Specialist\nFull-time · Singapore · 5 - 10 Years\n12 days ago', 'Cloud Native Developer\nFull-time · Hyderabad · 2 - 5 Years\n13 days ago']

jobs = [job.replace('\n',',') for job in listing_jobs]
print(jobs)
#['Senior Cloud Specialist,Full-time · Singapore · 5 - 10 Years,12 days ago', #'Cloud Native Developer,Full-time · Hyderabad · 2 - 5 Years,13 days ago']

Answer 3

import  re
list_of_lines = ['Senior Cloud Specialist\nFull-time · Singapore · 5 - 10 Years\n12 days ago', 'Cloud Native Developer\nFull-time · Hyderabad · 2 - 5 Years\n13 days ago']

just_replace = [re.sub('\n',",",lines) for lines in list_of_lines]

replace_then_split_to_list_of_lists = [re.sub('\n',",",lines).split(',') for lines in list_of_lines]

replace_and_then_split_to_flat_list = sum([re.sub('\n',",",lines).split(',') for lines in list_of_lines],[])

no_replace_split_flat_list = sum([lines.split('\n') for lines in list_of_lines],[])
