No special syntax for that, but you can combine the `sum()` function, a 
generator expression and `zip()`:

In [40]: sum(int(a == b) for a, b in zip('painter', 'paintor'))
Out[40]: 6

Or this way if you think it's more clear:

In [41]: sum(1 for a, b in zip('painter', 'paintor') if a == b)
Out[41]: 6
