Using %s in substring

Question

inputData = raw_input('time:')    
find_elem = wait.until(EC.presence_of_element_located((By.XPATH, "//*[contains(text(), '%s')]"% inputData)))

I do not know exactly why my code isn't working. I'm trying to pass my rawinput. If I get rid of %s and just put a string. It works. By not working I mean, the script is suppose to stop scrolling until certain time I do in raw_input but it doesn't but if I just pass in my string without %s it stops and works just as I wish to.

It sounds like you have one string that works (the one you hard-coded) and one that doesn't (the one you've made with %s). Print them out and spot the difference. — user94559

what means isn't working - do you get error message or what ? — furas

@furas In this case it needs to stop scrolling but continues to scroll. but if I get rid of %s it stops at the desired amount I want. — Biplov

Yes. I compared the both string by doing this string = "//*[contains(text(), '%s')]" % inputDate print string //*[contains(text(), '8 mins')] Just how I wanted it to. but when I use that in my actual function it doesn't work. — Biplov

You should use tuple for string formatting:

"%s" % (inputData)

UPDATE This fixed the problem, but I do not know why? I am not sure why this worked and fixed the problem. As suggested in comments, (inputData) is not even a tuple. And string formatting does not need the second argument to be tuple. The second argument can be a string.

I have no explanation for why this would fix something... (inputData) is not a tuple. (inputData,) would be. Regardless, you can certainly just use a string in this sort of construction "%s" % "hello world" works just fine.
