    Solving Python guessing number game

    I'm able to create a guessing number game, but I can limit the amount of guesses to less than 3. Can someone tell me what i'm doing wrong?

    Code:
    # Guess My Number
    # The computer picks a random number
    
    import random
    print "\tWelcome to 'Guess my number'!:"
    print "\nI'm thinking of a number between 1 and 100."
    print "Try to guess it in as few attempts as possible.\n"
    
    #set the initial values
    the_number = random.randrange(100) + 1
    guess = int(raw_input("Take a guess: "))
    tries = 1
    
    # guessing loop
    
    while (guess != the_number):
        if (guess > the_number):
            print "Lower..."
        else:
            print "Higher..."
                
        guess = int(raw_input("Take a guess: "))
    if tries > 3:
        print "You have more than 3 attempts, game over."
        tries += 1
    
    else:
        print "You guessed it! The number was", the_number
        print "And it only took you", tries, "tries!\n"
    
    
    
    raw_input ("\n\nPress the enter key to exit.")

    Please wrap your code in CODE tags so that the indentation doesn't get stripped out.

    It looks like you only update tries when it's greater than three. Your idea would work, but you also can't have

    Code:
    if: 
        code
    code
    else:
        code
    because Python won't know to associate the else with the if (can't tell since the parser here rips indentation out). Put the tries update someplace else to fix that.

      I made a few changes to your code. The statement to get guess is now inside the loop. Variable tries is incremented after the guess. The if statement that checks for high or low was modified: if >, elif<, else(must be correct guess). If tries == max_guesses, the game is over. Encapsulate the code in a function. Use return to exit the while loop.
      Code:
      import random
      print "\tWelcome to 'Guess my number'!:"
      print "\nI'm thinking of a number between 1 and 100."
      print "Try to guess it in as few attempts as possible.\n"
      
      def guess_num(num, max_guesses):
          # guessing loop
          tries = 0
          while True:
              guess = int(raw_input("Take a guess: "))
              tries += 1
              if guess > num:
                  print "Lower..."
              elif guess < num:
                  print "Higher..."
              else:
                  print "You guessed it! The number was", num
                  print "And it only took you %d tr%s!\n" % (tries, ['ies', 'y'][tries==1 or 0])
                  return
      
              if tries == max_guesses:
                  print "You have had %d guesses. Game over." % max_guesses
                  return
      
      the_number = random.randrange(1,101)
      max_guesses = 3
      guess_num(the_number, max_guesses)
      
      raw_input ("\n\nPress the enter key to exit.")

        Thanks bvdet. The book "Python Programming second edition hasn't shown the "def" command yet.
        The original exercise - Modify this program so the player has a limited number of guesses. The chp covers import random, randomrange, while loop, while true, if, if-else loop and if elif loop. Is there a way I can do with the def command?

          The original exercise modify this program to limit the amount of guesses.
          Chapter covers if, if-else, if-elif, if-elif-else, while, while True, import random, randrange(), raw_input and comparison operators. How can I do it without using the def command.
          Original exercise that I have to modify listed below.

          Code:
          # Guess My Number
          
          # The computer picks a random number
          #  The player tries to guess it and the computer lets
          #  The player know if the guess is too high, too low
          #  or right on the money
          
          import random
          
          print "\tWelcome to 'Guess my number'!:"
          print "\nI'm thinking of a number between 1 and 100."
          print "Try to guess it in as few attempts as possible.\n"
           
          #set the initial values
          # the_number = random.randrange(100) + 1
          # guess = int(raw_input("Take a guess: "))
          # tries = 1
          #  
          # # guessing loop
            
          while (guess != the_number):
             if (guess > the_number):
             print "Lower..."
             else:
             print "Higher..."
          
          guess = int(raw_input("Take a guess: "))
          
          tries += 1
          
          print "You guessed it! The number was", the_number
          print "And it only took you", tries, "tries!\n"
          
           raw_input ("\n\nPress the enter key to exit.")

            Could you clarify what your problem or question is?

              dseto's programming course hasn't covered functions yet.

              Just modify the condition in the while-loop so that the loop also stops when the number of tries is too high. You'll need the and operator.

                Hi, I've taken a look at your code and your on the right track. Remember loops are an extremely important part of any program especially one like this. Below is a working guess the number game that requires you to input the number of max tries when you call the function.

                Code:
                #! /usr/bin/env python
                
                # Guess the number game
                
                import random
                
                def main(max):
                    print "\tWelcome to 'Guess my number'!"
                    print "\nI'm thinking of a number between 1 and 100."
                    print "Try to guess in as few attempts as possible.\n"
                    num = random.randrange(101)
                    tries = 0
                    guess = ""
                    while guess != num:
                        guess = int(raw_input("Take a guess: "))
                        if guess > num:
                            print "Too high."
                        elif guess < num:
                            print "Too low."
                        tries += 1
                        if tries >= max:
                            print "Sorry, you took too many guesses. Game Over"
                            exit()
                    print "Congratulations!"
                    again = raw_input("To play again press Enter. Type anything else to quit.")
                    if again == "":
                        main()
                    else:
                        exit()
                
                main(3)
                The business part of this code is lines 14-23. thats the important while loop that keeps the game going. As you can see it will keep iterating while the variable 'guess' does not equal variable 'num' (while guess != num:)

                This code doesnt have any try-except statements or any error checking for user input or anything like that but it is working. If you need any additional explanation please post again. Thanks
