Hello.  I think you code is Python 2.7.  My solution uses Python 3 but I ca=
n help you convert it if the solution is what you are looking for.  My appr=
oach as to create a class that tries to guess the right number.  This code =
also eliminates raw_input.  I didn't know how important having it respond v=
ia raw_input is to you.  Code follows:

import random
import sys

class Guesser():
    def __init__(self):
        self.low =3D 1
        self.high =3D 100
       =20
    def getRand(self,x,y):
        num =3D random.randint(x,y)=20
        return num    =20
      =20
    def guess(self,guess,boundary):
        if boundary =3D=3D ">":
            self.low =3D guess
        elif boundary =3D=3D "<":
            self.high =3D guess
        else:
            self.low =3D 1
            self.high =3D 100
        return self.getRand(self.low,self.high)
   =20
    def playagain(self):
        choice =3D ['Y','N']
        return random.choice(choice)
      =20

run =3D 0

while run =3D=3D 0:=20
    guess=3D1
    guesses=3D0
    guessestaken =3D 0
    comp =3D Guesser()
    num =3D comp.getRand(1,100)=20
    result =3D ""
    print ("I am thinking of a number between 1 and 100")=20
    while guesses =3D=3D 0:=20
        guessestaken +=3D 1
        try:=20
            guess =3D comp.guess(guess,result) # replaces input
        except: =20
            print("Unexpected error:", sys.exc_info()[0])=20
            raise
         =20
        print("Your guess:", guess)   =20
        if guess =3D=3D num:=20
            print('Correct! It took you', guessestaken, 'guesses!')=20
            guesses =3D 1
        elif guess > num:
            print("My number is lower")=20
            result =3D "<"
        else:=20
            print("My number is higher")=20
            result =3D ">"
    print("Do you want to play again?")=20
    playagain =3D comp.playagain()    # replaces input
    print(playagain)
    if playagain =3D=3D "N":=20
        run =3D 1

Please let me know if you have questions or would like to discuss this solu=
tion further.

Cheers!
