Hi,
I am not sure,  the regular expressions are best suited for this task,
but if you have a predictable simple parameter list (with ho
recursion, escaping commas or equal signs etc.), it might be viable;
how about e.g. this pattern?

>>> re.findall(r'([^=\s,]+)=([^=\s,]+)', s)
[('a', 'b'), ('c', 'd')]
>>>
