Pattern matching of `space` in mathematical expressions

Question

I want a pattern which can match both of these expressions:

expr1 = `a + b` 
expr1 = `a+b`

Thanks.

I know the pattern for both the expressions. I wanted to know if there is a common pattern for both of them. Thanks. — Arihant Parsoya, Apr 18 '17 at 09:16

try this:

`(\w+)\s*(\S)\s*(\w+)`

first hit gets you the first variable (a), second hit gets you the operand (+) and third hit gets you the second variable (b)
Works also for python
