Get everything between two spaces including a word stem

I am trying to extract the filename from the following string:

s = '[download] /tmp/743979_file.mp4 has already been downloaded'

Here is what I have so far:

>>> re.search(r'(\s).+_file[^\s]+', s).group()
' /tmp/743979_file.mp4'

How would I get everything after the first space, before the second space, and which includes the word _file ?

Use \S to match any non-space character. So \S* would match zero or more non-space characters. \s is just an opposite of \S where \s matches any kind of space character and \S matches any kind of non-space character.

>>> s = '[download] /tmp/743979_file.mp4 has already been downloaded'
>>> re.search(r'(?<=\s)\S*_file\S*', s).group()
'/tmp/743979_file.mp4'

OR

simply,

>>> re.search(r'\S*_file\S*', s).group()
'/tmp/743979_file.mp4'

OR

>>> s = '[download] /tmp/743979_file.mp4 has already been downloaded'
>>> m = s.split()[1]
>>> if '_file' in m:
        print(m)


/tmp/743979_file.mp4

Another simple solution could be using split:

print '[download] /tmp/743979_file.mp4 has already been downloaded'.split()[1]
