Blanks can be placed between names and tuples or not, but they surely are placed beween two groups. I would like to process this string in order to get a dictionary like this:

Stop there!  :)

I'd use string functions.  If you can control the string output to drop 
the spaces and always output in namex(a,b)<space>namey(c,d)... format, 
try starting with

 >>> "name1 name2(1) name3 name4(1,4) name5(2)".split()
['name1', 'name2(1)', 'name3', 'name4(1,4)', 'name5(2)']

then create the dict from the result.
