Make a python function that solves this prompt: Given an array of strings strs, group the anagrams together. You can return the answer in any order.

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.

Here is a Python function that groups all the anagrams together in separate lists.

from collections import defaultdict

def groupAnagrams(strs):
    a = defaultdict(list)
    for s in strs:
        count = [0] * 26

        for c in s:
            count[ord(c) - ord("a")] += 1
        a[tuple(count)].append(s)   
    return a.values()
