In cell 61 you can get rid of new line by using replace. e.g re.search('.+', str1, flags=re.DOTALL).group().replace("\n", "")

[vikramsarabhai]

Thanks for videos they are really good!
The '\s' at the end, must be a special character in Regex not in python, since in python that '\s'
does nothing, not like \n which sets you into a new line.

What does the outer parenthesis do in "(re.findall('\S+', string))"? Looks like it doesn't convert the list into tuple

[nagavolukrishna]

Thanks for the videos! They are probably the best ones out there for explaining regex. (y)
I have trouble matching a backslash.
When i do the following, it prints out two backslashes even though my string just has one -
>>> re.findall('[A-Z, "\\\]', 'Hi There, he said "see ya" \ ')
['H', 'T', ', ', '"', '"', '\\']
>>>
Trying the below just errors out -
>>> re.findall('[A-Z, "\\]', 'Hi There, he said "see ya" \ ')
