I'm looking for the way of comparing two strings and being able to get back, as separate strings:
Example:
A = "123 ABC"
B = "135 AZ"
thingamajigger(A, B) # would give all these:
intersect = "13 A" # (includes space)
exclusion = "2BCZ5"
a_minus_b = "2BC"
b_minus_a = "5Z"
a_minus_b is quite simple... but if there's one of those fancy one-liner ways to pull it off, then I'm open.
for i in B:
A = A.replace(i, "")
It's a bit like boolean operations on strings.

Approach: Count the frequencies of all the characters from both strings. Now, for every character if the frequency of this character in string s1 is freq1 and in string s2 is freq2 then total valid pairs with this character will be min(freq1, freq2). The sum of this value for all the characters is the required answer.
If you want to maintain a count of the number of characters in common, you should use collections. Counter instead of set .
Use set:
s = set("123 ABC")
t = set("135 AZ")
intersect = s & t # or s.intersection(t)
exclusion = s ^ t # or s.symmetric_difference(t)
a_minus_b = s - t # or s.difference(t)
b_minus_a = t - s # or t.difference(s)
