Python - 在不依赖“\\n”的情况下难以连接多行

Question

I'm using beautifulsoup to find all locations on a webpage, and it does.

get_location = second_soup.find_all('span', attrs={"class": "location"})
for local in get_location :
  if local:
    s = local.text
    s = s.replace("\n", "")
    s = s.replace("-", "") #removes the -
    s = s.split("|", 1)[0] #removes | and everything after it
    s = ''.join([i for i in s if not i.isdigit()]) #removes numbers from zip
    s = s.lstrip() #removes spaces
    s = s.rstrip() #removes spaces
    print(s)

I get the following result:

New York, NY
Brooklyn, NY
Johnville, KY

However, I need it like so:

New York, NY, Brooklyn, NY, Johnville, KY

Things I've tried:

1) instead of s.replace("\\n", "") using s.replace("\\n", ", ")

Results are identical, except when there was \\n it replaced with , So I get:

, New York, NY, 
, Brooklyn, NY, 
, Johnville, KY, 

2) Removing replace and using s = '\\n'.join([line.strip() for line in s])

Results are weird, I get one character per line. Such as:

N
E
W


Y
O
R
K

Edit

The reason I need it in a one-liner is that I'm inserting that into an array, and I'm unable to insert more than one line into an array, so I get New York, NY and that's it.

That's how I want my array:

['New York, NY, Brooklyn, NY, Johnville, KY', 'Boston, MA, Miami, FL'] etc

Answer 1

I can't test since we don't have your data, but I think you want something like:

get_location = second_soup.find_all('span', attrs={"class": "location"})
rebuilt = []
for local in get_location :
    if local:
        s = local.text
        s = s.replace("\n", "")
        s = s.replace("-", "") #removes the -
        s = s.split("|", 1)[0] #removes | and everything after it
        s = ''.join([i for i in s if not i.isdigit()]) #removes numbers from zip
        s = s.strip() #removes spaces
        rebuilt.extend(s)
print(rebuilt)

Answer 2

You could do the following to replace newlines with commas:

s = ', '.join(s.split('\n'))

However, it would be helpful if you could provide an example data blob that you're working with.

Answer 3

In the last line of your 'if' loop - print(s), as each line is printed with print's 'end' parameter as set to default = '\\n'. Therefore, its printed in next line for each loop. So if you set the parameter to comma(,) or as per your choice then output will be printed in same line. Try this:--

print(s, end=',')
