Thank you ALL for help.
However It does not work as I would need.
Let's suppose I have
a={'c':1,'d':2}
b={'c':2}
but
a.update(b)
will make
{'c': 2, 'd': 2}
and I would need
{'c': 3, 'd': 2}
(because `c` is 1 in `a` dictionary and `c` is 2 in `b` dictionary, so
1+2=3)
How can be done that?
Thank you for the reply
