re.compile('\s+', flags = re.UNICODE)
The above code gives the following warning in python3.
SyntaxWarning: invalid escape sequence \s
I fix it by using r'\s+'. Is it a correct way to fix the problem?

Yes that is, you can either use a raw string r'\s+' or alternatively escape the backslash with '\\s+'.
