The Log View Content, like:

This is the first time input.

This is the fourth time input.

Sorry, I don't quite understand your question. Can you explain it with a minimal code example?

[virginiaWu]

OK.

res_output = ui.log().style('margin-left: 10%; min-height: 430px; width: 85%;')
res_output.push("Start do power cycle")
s_time = time.time()
while time.time() - s_time < 30:
   res_output.push("..")    #  want to all "........." string in the one line, not ".." in one line, ".." in another line 
res_output.push("Power cycle done.")

I see. Unfortunately ui.log is completely based on lines separated by \n and it's not possible to change lines that already have been pushed. As a workaround you can repeatedly clear() and push() the line. Otherwise we would need to extend ui.log to allow popping or updating the last line.

[virginiaWu]

I got it. Do you have the plan to extend the ui.log to allow popping or updating the last line?

[falkoschindler]

Not yet. But I'll convert this discussion into a feature request.

Depending on your use case you might find xterm useful. You should be able to interact with it just like a terminal although I haven't exercised it much with advanced inputs. This is a bit of a verbose example:
#1846

Also, implemented slightly differently in my personal project:
