Thanks for bothering. I'm sorry for having been too terse. The snippet 
was from an html download (wget 
https://finance.yahoo.com/quote/HYT/history?p=HYT). Here's a little more 
of it:  ".  .  .  ED_SHORT":"At close: {date} 
{time}","MARKET_TIME_NOTICE_CLOSED":"As of {date} {time}. 
{marketState}","MARKE . . .". I suppose the browser gets the values 
whose names appear in braces, dialoguing with the server. I believe it 
is javascript. I see sections marked <script> . . . section here . . . 
</script>. If it is javascript, the question would be how to run 
javascript in python, unless it runs on the server by requests sent by 
python from my end.
