bvr's answer will address the immediate needs of the problem.
A recommendation is to use exists instead of defined to check if the string is present in the dictionary. This will ensure that non-words such as 'bemyg' will never become keys in the dictionary hash.

只需将
find_words中的print替换为对变量的赋值，并在for循环结束后打印它。Simply replace
printinfind_wordswith an assignment into variable and print it after theforloop ends.bvr的答案将解决问题的直接需求。
建议使用
exists而不是define检查字符串是否存在于字典中。这将确保诸如'bemyg'这样的非单词永远不会成为字典哈希中的键。bvr's answer will address the immediate needs of the problem.
