I’m trying to use the site http://pandoc.org/try/ to convert html text to latex. My python code is as follows::
import requests
mathml = "<math display='block'xmlns='http://www.w3.org/1998/Math/MathML'><mrow><mfrac><mrow><mo>−</mo><mi>b</mi><mo>±</mo><msqrt><mrow><msup><mi>b</mi><mn>2</mn></msup><mo>−</mo><mn>4</mn><mi>a</mi><mi>c</mi></mrow></msqrt></mrow><mrow><mn>2</mn><mi>a</mi></mrow></mfrac></mrow></math>"
def convert_url_pandoc_2_latex(url_pandoc='https://pandoc.org/try/', mathml=mathml):
info = {'text': mathml, 'from': 'html', 'to': 'latex'}
r = requests.get(url_pandoc, params=info)
return r
r = convert_url_pandoc_2_latex()
type(r) = requests.models.Response
When running r.content I get the following return:

The next passage comes empty:
<pre id="results"></pre>
But it should come in the following way:
<pre id="results">\[\frac{- b \pm \sqrt{b^{2} - 4ac}}{2a}\]</pre>
This last result I get when I do the procedure manually and access "Inspect" page.
How to modify my code to get [ frac{- b pm sqrt{b {2} - 4ac}}{2a}\] ?
thank you so much for your reply. It worked perfectly.
