Note: I am fairly new to this but can't figure this problem out. I want to find the age of people as a question and for them to enter it themselves. The problem is, is when I want to subtract c - b it says error, because both of them are strings and you cannot subtract strings. How can I convert these strings into numbers that let me add and subtract them. As if I said it was year 2000 and I was born 1999, it would say you are 20001999 instead of 1 years old. Is there another way to right this or a way to convert these strings into numbers? Much would be apreciated.
a = raw_input("Enter name: ") b = raw_input("Enter the year you were born: ") c = raw_input("Enter the year it is now: ") print "You,",a,",are ",c - b,"years old."
