If you want to remove any whitespace (i.e.Space, Tab, CR and Newline), use this:

import re

without_spaces = [re.sub(r'\s+', '', item) for item in original]

If you need to replace only regular spaces, use the already suggested solution

without_spaces = [item.replace(' ', '') for item in original]

Use str.translate() on each element in a list comprehension:

[v.translate(None, ' ') for v in original]

Here None means don't replace characters with other characters, and ' ' means remove spaces altogether. This produces a new list to replace the original.

The above only removes just the spaces. To remove all whitespace (newlines, tabs, feeds, etc.) simply expand what characters should be removed

[v.translate(None, ' \t\r\n\f\x0a') for v in original]

str.translate() is the fastest option for removing characters from text.

Demo:

>>> original = ['16', '0000D1AE18', '1', '1', '1', 'S O S .jpg', '0']
>>> [v.translate(None, ' \t\r\n\f\x0a') for v in original]
['16', '0000D1AE18', '1', '1', '1', 'SOS.jpg', '0']

You can use 

k=[]
for i in original :
    j = i.replace(' ','')
    k.append(j)
