python - input as parameter of function : I'm really sorry I'm really new to this. I'm wrote a script for a 'robot' that adds one to a user response, but my code does not run. I'm really new and wondered if anybody could help me understand what I'm doing wrong 

> import time

> print("hello, I am the addition bot, I add one to any number you know")
time.sleep(0.7)

> print("Quick!")
time.sleep(0.2)

> print("My boss is coming, please give me a number!")
time.sleep(0.4)

> print("Quick!")
time.sleep(1)

> def addOneTo(number):
    return number + 1

> oldNumber = input()

> print(addOneTo(oldNumber))
