That's a bit tricky. You have LHS = RHS where RHS includes all the  
following text *except* the very next word before the following = (which  
is the LHS of the next expression). Or something like that :)

py> import re
py> s = "a = 4.5 b = 'h'  'd' c = 4.5 3.5"
py> r = re.compile(r"\w+\s*=\s*.*?(?=\w+\s*=|$)")
py> for item in r.findall(s):
...   print item
...
a = 4.5
b = 'h'  'd'
c = 4.5 3.5
