Python very short and simple
\ndef largestWordCount(self, messages: List[str], senders: List[str]) -> str:\n\tdic = defaultdict(int)\n\tfor s, m in zip(senders, messages):\n\t\tdic[s] += m.
```\ndef largestWordCount(self, messages: List[str], senders: List[str]) -> str:\n\tdic = defaultdict(int)\n\tfor s, m in zip(senders, messages):\n\t\tdic[s] += m.count(\' \') + 1\n\treturn max([(c, s) for s, c in dic.items()])[1]\n```
