How can you retrieve the description of a pull request associated with a commit?

I've tried the following;

commit = org.get_repo("my-repo").get_commit(sha="c2144da718afdbc343115e995f585d6d58c7ec6bd")
print(commit.author)
print(commit.committer)
print(commit.last_modified)

Which returns the details of the commit, however, can not find how to fetch the commit message.
I thought it might be;

print(commit.get_comments())

But that doesn't retrieve the commit message.

Does anyone know if it's possible?

thanks in advance!

該 issue 提到了 org.get_repo(...).get_commit(...) 和 commit.get_comments()，但沒有提供任何 repository 檔案或測試。首先釐清所需值是 commit message 還是相關 pull request 的描述，然後檢查這些 API 進入點；只有為所要求的值驗證出一條擷取路徑後，才算完成。
