I wish this helpful for you There is no actual whitespace in the list. It is just how it's __str__ function is coded (the way it prints out). If you want to print it out without any spaces the best way to do it is convert it to a string first:
code :
>>> test = [2, 32, 123, 1]
>>> test
[2, 32, 123, 1]
>>> print(str(test).replace(" ",""))
[2,32,123,1]

it should still fix some issue There is a special-case shortcut for exactly this use case!
If you call str.split without an argument, it splits on runs of whitespace instead of single characters. So:
code :
>>> ' '.join("Please \n don't \t hurt \x0b me.".split())
"Please don't hurt me."

I hope this helps . You can strip each line. Running it as a generator could also save you some memory if you're working on a big file.
Also, looks like you're working on a UTF-8 file with a BOM (which is sort of silly, or at least unnecessary) for the first several characters, so you need to open it differently.
code :
import codecs

def strip_it_good(file):
    with codecs.open(file, "r", "utf-8-sig") as f:
        for line in f:
            yield line.strip()

like below fixes the issue I have list of strings includes whitespace and \n like below. , You need to use a combination of map and strip:
code :
>>> L = ['XXXXX', '\n\n YYYYYYY\n \n', 'HHHHH', '\n\n ZZZZZ\n \n']
>>> list(map(str.strip, L))
['XXXXX', 'YYYYYYY', 'HHHHH', 'ZZZZZ']

this one helps. Regex is your friend in cases like this, you can simply iterate over your list applying a regex substitution
code :
import re
r = re.compile(r"^\s+")

dirty_list = [...]
# iterate over dirty_list substituting
# any whitespace with an empty string
clean_list = [
  r.sub("", s)
  for s in dirty_list
]
