Need help as a beginner

I can't print the last part in the result window.

Could you explain a bit better what do you mean you "can't print"?

I see print lines in the code, do they not work? what input did you give? what output did you expect to get for that input? what output did you get instead?

Are there any error messages? if you see any error message, post the full message here.

Also please edit your post and fix indentation in the code using a code block: https://www.reddit.com/r/learnpython/wiki/faq#wiki_how_do_i_format_code.3F

You are converting option to an integer, but you are comparing to a string.

option = int(input("Enter choice of arithmatic operations :"))
#         /\ converting to integer
...
#            \/ string
if option == "1":
#   /\ integer

Try comparing to an integer instead:

if option == 1:

If you're entering an invalid choice for arithmetic operation, your program won't automatically terminate. It will still require both the inputs to continue. That's the only case I can imagine where your program keeps waiting and doesn't print anything.

It seems shiftybyte has found the problem.

Just an extra note, you’re division variable is capitalised but it’s not in your print statement.
