Question

I have two dictionary corresponding to character counts of two different strings. I want to check if they are made up of same characters or not, regardless of the frequencies of the characters.

---

Say, I have two strings caars and racs
They are made up of same characters a,c,r,s

---

I know of cmp method to compare two dictionaries, which also compares both the key-value pairs. But I don’t want to compare their values or counts.

---

Just in case, you may ask, why do I have dict then for both the strings. Well, I do need them in some other part of the problem. So, why not use them.

---

How can I do this in python quickly?

Answer 1

You want to use a set.

In [32]: str1 = 'caars'

In [33]: str2 = 'rats'

In [34]: set(str1) == set(str2)
Out[34]: False

In [35]: str3 = 'racs'

In [36]: set(str1) == set(str3)
Out[36]: True
