Replace

return render_template("index.html", value='number')

with

return render_template("index.html", value=number)

You need to send variable not string. If you use value='number', value is a string which is 'number' or anything inside the quotes. For example if you set value='another number', then you will see 'Your random number is another number.'

If you want to use the value of 'number' variable use it without quotes. This will ensure you are passing the value of the number variable and not a string.
