Hi,
you can create a new tuple with the con= verted elements from the original one
using a list comprehension = and the regular expression replacement, it could be e.g.

>>> import re
>>> tuple([re.sub(r"\s+&= quot;, " ", element) if isinstance(element, str) else element for= element in ("qw e", 1, 2, None, "U\nN IC", &#= 39;Q\tW E')])
('qw e', 1, 2, None, 'U N IC', 'Q W E')
>>= >

re.sub(...) replaces one or more whitespace= characters (space, newline, tab ...) with a single space - the pattern can= be tweaked as needed (e.g. the pattern r" *\n *| +" would only = handle spaces and newlines explicitely).
This replacement is only applied on string elements of the tuple, othe= rs are left unchanged
=A0if isinstance(element, str) is meant for= =A0python 3, for python 2=A0 if isinstance(element, basestring) would be m= ore appropriate
the elements are collected in a list using this list comprehension
and this intermediate list is finaly converted to a tuple if this im= mutable container is needed.

hth,
