python regular expression help

[Qilong Ren]

Hi,

Thanks for reply. That actually is not what I want. Strings I am dealing with may look like this:
     s = 'a = 4.5 b = 'h'  'd' c = 4.5 3.5'
What I want is
     a = 4.5
     b = 'h' 'd'
     c = 4.5 3.5

pattern = re.compile(r'\w+\s*=\s*[0-9]*.[0-9]*\s*')
lists = pattern.findall(s)
print lists
['a=4 ', 'b=3.4 ', 'c=4.5']
