+Exercise 25: Guessing Game Two
+
+In a previous exercise, we’ve written a program that “knows”
+a number and asks a user to guess it.
+
+This time, we’re going to do exactly the opposite. You, the
+user, will have in your head a number between 0 and 100. The
+program will guess a number, and you, the user, will say
+whether it is too high, too low, or your number.
+
+At the end of this exchange, your program should print out how
+many guesses it took to get your number.
+
+'''
+# Solution
+def main():
+    import random
+    guess_log = [random.randint(0, 101)]
+    log_dict = {'lower':[0], 'higher':[100]}
+    while True:
+        print(guess_log[-1])
+        evaluate = input('Tell me my number is:\n1: too low\n2: too high\n3: Right\n')
+        try:
+            evaluate = int(evaluate)
+            if evaluate == 1:
+                log_dict['lower'].append(guess_log[-1])
+                guess_log.append(int((min(log_dict['higher']) + max(log_dict['lower']))/ 2 ))
+            elif evaluate == 2:
+                log_dict['higher'].append(guess_log[-1])
+                guess_log.append(int((min(log_dict['higher']) + max(log_dict['lower']))/ 2 ))
+            else:
+                print('Yeah!\n', guess_log)
