It is giving an output of 'NaN' in the output.
If the python program is run alone it is giving the correct output.
Can anyone please help.
Is it also possible to separate the python and the javascript to two different
files. If so how will I get/transfer the data in/from HTML .
Thanks
At a guess I'd say that it's because you have:
setInterval("startTime();",1000);
which will call 'startTime' with no arguments, but:
function startTime(myvar)
which means that it's expecting an argument.
