python - How to calculate percent and add it to the amount -

-

one question. code is:

    preis = input("preis: ")     preis1 = preis / 100     preis2 = preis1 * 1.9     preis3 = preis + preis2

lets preis input user makes 100 , should 100 / 100 = 1 (result price1 1). final output should 101.9. not right because not working :)

for one, input() returns string, you'll need convert int.

preis = int(input("preis: "))

apart that, code should work, might want read style guide; don't need declare new variable every step.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
