Using keyboard input to store values of a counter

Question

I have a while loop that navigates to a webpage that I manually inspect. What I need to be able to do is press the enter key and have the counter stored. Ideally everything would work like this:

from selenium import webdriver as wd
import time

url = [www.example.com,www.google.com]
ff = wd.Firefox()
stored_url_number = []

i=0
while i<len(url):
    ff.get(url[i])
    time.sleep(5)
    if enterispressed:
         stored_url_number.extend(i)
    i +=1

Is there a simple way to create an 'enterispressed' function in python?

Specifically, I want the program to run as normal to the next iteration unless enter is pressed, in which case I want it to perform the .extend(i) action and then move on.

Many thanks

I'm not sure what you mean by the case "non enter pressed", somthing else pressed? Non key pressed for some time? — Ohad Eytan, Jul 14 '16 at 11:33
Non pressed key for some period of time (almost certainly will be set to the same as the sleep time on the line above)? — draco_alpine, Jul 14 '16 at 11:36
ah they look really good! I'll work through them, put what I find works as an edit on your answer and then accept it. — draco_alpine, Jul 14 '16 at 12:29

Simple way is to get input from the user and check if it's empty:

while i<len(url):
    ff.get(url[i])
    time.sleep(5)
    x = input()
    if x=="":
         stored_url_number.extend(i)
    i +=1

You can skip the checking if you don't care what the input is:

while i<len(url):
    ff.get(url[i])
    time.sleep(5)
    input()
    stored_url_number.extend(i)
    i +=1

Edit:

That works for python 3.

For python 2 use raw_input() instead of input().

Edit 2:

If you want to limit the time for the press you should look here or here

I've run some test cases with this and it seems that this has a few issues. I've edited the question to reflect some of these, but the return key is not a a legitimate input for input() and giving an EOF error. – draco_alpine Jul 14 '16 at 11:20
@draco_alpine I just checked it and it's works on python3 but not on python2.7 :( – Ohad Eytan Jul 14 '16 at 11:24
