Multi-way Decisions (House or Senate)

We will probably not have time to get to this, but in case you want to see code that I wrote for this problem:



In [ ]:

    
##eligible v1.0
def eligible():
    job = raw_input("Would you like to me a member of the Senate or the House?: ")
    job = job.lower()
    age = input("How old are you?: ")
    citizen = input("How many years have you been a citizen of the United States?: ")
    if job == "senate":
        if age >= 30:
            if citizen >= 9:
                print "You are eligible to be a Senator!"\
                      "If for some reason you want to be a Senator."
            else:
                print"You are ineligible to be a Senator -"
                "you must be citizen for 9 years."
        else:
            print "You can't be Senator - you are too young."\
                
    elif job == "house":
        if age >= 25:
            if citizen >= 7:
                print "You are eligible to be a member of the House! " \
                  "Although why you would want to be is anyone's guess."
            else:
                print "You are ineligible to be a member of the House -"
                "You must be a citizen for 7 years."
        else:
            print "You are ineligible to be a member of the House - "\
            "You are too young.  I know, they act like chidren, but they"
            " are technically all over the age of 25."
    else:
        print "That's not a job - try again!"
