Trying to send html content in a JSON format using Python to Joomla API

Question

Variable 'article' prints like this:

[MessageContentText(text=Text(annotations=[], value='some long <p class="break">html</p> here'), type='text')]

Python code looks like JSON like this

data = {
        'title': {blog_post_idea},
        'alias': {slug},
        'articletext': {article},
        'catid':'0',
        "language": "*"
}

I tried article["value"] and article[1] various list type errors. I don't know if the API I am sending to can decode base64 or not. I am trying to send html.
