この作業にはGCPとBloggerの連携の手続きが先に必要です。

test.pyに以下のコードを記述します。
公式のサンプルを一部変更して持ってきています。

test.py

RETRIABLE_STATUS_CODES = [500, 502, 503, 504]

    while response is None:
        try:
            #print ("Uploading file...")
            status, response = insert_request.next_chunk()
            if response is not None:
                if 'id' in response:
                    id = response['id']
                    #print ("Video id '%s' was successfully uploaded." % id)

        # value for better recovery on less reliable connections.

        # Setting "chunksize" equal to -1 in the code below means that the entire
        # file will be uploaded in a single HTTP request. (If the upload fails,
        # it will still be retried where it left off.) This is usually a best
        # practice, but if you're using Python older than 2.6 or if you're
        # running on App Engine, you should set the chunksize to something like
        # 1024 * 1024 (1 megabyte).

以前のgetRss()から上記のyoutube_upload()を呼び出します。

test.py

def getRss():
    with open('/tmp/temp.mp3' ,mode='wb+') as f:
        f.truncate(0) 
    rssUrl = 'https://news.google.com/news/rss/headlines/section/topic/TECHNOLOGY'
    rssLang = '?hl=en-US&gl=US&ceid=US:en'
    feed = feedparser.parse(rssUrl + rssLang)
    for entry in feed.entries:
            link = entry.get('link')
            getBody(link)
    makeVideo()
    youtube_upload('この動画のタイトル','この記事の説明',['この動画のタグ'])
