How do I fix this guessing game of numbers 1 - 50? - python

The following project requires: Your program should implement a simple guessing game with the following requirements:
Generate a random number between 1 and 50 and then have the user guess the number. The program should tell the user whether they have guessed too high or too low and allow them to continue to guess until they guess the number or enter a 0 to quit.
When they guess the number it should tell them how many guesses it took. At the end, the program should ask them if they want to play again.
For example:
Enter a guess 1-50, or 0 to quit: 25
Too high!
Enter a guess 1-50, or 0 to quit: 15
Too low!
Enter a guess 1-50, or 0 to quit: 100
Guess must be between 1 and 50!
Enter a guess 1-50, or 0 to quit: 18
That's it! You took 3 guesses to get the number.
Would you like to play again? (Y/N)
I currently have everything settled except for two issues. I cannot seem to get the play again feature to work and for some reason the first number that is guessed will not say whether it is too low or too high.
My following code:
import random
play = True
randomNum = 45 #random.randrange(1,50)
guesses = 1
num = int(input())
print("Enter a guess 1-50, or 0 to quit:", num)
if num > 50 or num < 1:
print('Guess must be between 1 and 50!')
if num == randomNum:
print("That's it! You took", guesses, "guess to get the number.")
#print("Guess must be between 1 and 50!")
while num != randomNum:
guesses += 1
num = int(input())
print("Enter a guess 1-50, or 0 to quit:", num)
if num == 0:
break
elif num > 50 or num < 1:
print('Guess must be between 1 and 50!')
elif num > randomNum:
print("Too high!")
elif num < randomNum:
print("Too low!")
if num == randomNum:
print("That's it! You took", guesses, "guesses to get the number.")
print("Would you like to play again? (Y/N)")
letter = str(input())
if letter != 'Y':
play = False
I explained above what I have tried. I do believe that the issue is that the first guess does not enter the while loop. Unsure of how to fix this though.

First issue is that your while cycle only lasts until a number is guessed. So that means after you guess the first random number, your program will finish.
In order to avoid that you should declare your $play = True$ boolean on top of the cycle so you can declare your while cycle something like this:
play = True
while play:
# game goes here.
print("Would you like to play again? (Y/N)")
letter = str(input())
if letter != 'Y':
play = False
Then your cycle should continue while letter is Y or play remains True.
Second issue is that you ask for the number outside the cycle. That is not necessary, you can ask it inside after you construct your code like the example above.
I hope this clears things up.
ps. This is my first answer, so please point out if I did something wrong!

Python: Can't figure out why my loop skips the right answer

I decided to make a small project to test my skills as I continue to learn Python in my free time.
The game consists of the user guessing the right number that is randomly generated within a certain amount of tries. The user first enters the range of numbers they want to guess from. Then they get their first try at guessing the right number (I have the randomly generated number displayed on purpose to test my code as I continue). I cannot figure out why when I enter the same number as the randomly generated number, I get the error that would pop up when you guess the wrong number. But if I enter that same number after I am prompted to guess for the randomly generated number again, I get a success note prompted to me. I've been trying different variations all day.
import random
print("Guessing Game")
rangeAmount = int(input("From 1 to what number do you want to guess from (Maximum amount is 50)? "))
correctNum = random.randint(1, rangeAmount)
wrongCount = 0
userScore = 0
print("-" * 50)
while rangeAmount:
if 1 < rangeAmount < 10:
guesses = 3
print("Guesses allowed: 3")
break
if 1 < rangeAmount < 20:
guesses = 4
break
if 1 < rangeAmount < 30:
guesses = 5
break
if 1 < rangeAmount < 40:
guesses = 6
break
if 1 < rangeAmount < 50:
guesses = 7
break
print("Correct number: " + str(correctNum))
print("Guess amount: " + str(guesses))
print("-" * 50)
userGuess = input("Make a guessing attempt for the correct number: ")
while userScore != 3:
if wrongCount != guesses:
if userGuess is correctNum:
userScore += 1
print("You got the right answer")
break
else:
wrongCount += 1
print("Current guess count: {}".format(wrongCount))
userGuess = int(input("Wrong answer, try again: "))
if wrongCount == guesses:
print("Out of guesses, score is : {}".format(userScore))
userScore -= 1
break
if userScore == 3:
print("You won the game!")
Output:
Guessing Game
From 1 to what number do you want to guess from (Maximum amount is 50)? 23
--------------------------------------------------
Correct number: 5
Guess amount: 5
--------------------------------------------------
Make a guessing attempt for the correct number: 5
Current guess count: 1
Wrong answer, try again: 5
You got the right answer
Process finished with exit code 0
First, your maximum range is 50, but it is not included in your first while loop (ends at 49), change the last line to <= 50. You can remove the while loop, and change the if statements to if/elifs. Second, your indentation is off in the while userScore != 3: loop, but that could just be a copy/paste error.
And now for the most likely cause of the error,
userGuess = input("Make a guessing attempt for the correct number: ")
is a string, don't forget to make it an int before you compare it to another int.

How to fix guessing game

The objective is to create a simple program that generates a number between 1 and 100, it will then ask the user to guess this, if they guess outside of the number range it should tell them to guess again, if not it should tell them whether their guess was too high or too low, prompting them to guess again. Once they do guess the correct number it should tell them they've won and the number of tries it took for them to guess it correctly.
Here is what I have so far
import random
def play_game():
number = random.randint(1, 100)
print("Guess a number between 1 and 100 inclusive.")
count = 1
while True:
guess = int(input("Your guess: "))
if guess > 0 and guess <= 100:
#the age is valid
return play_game
else:
print("Invalid number.")
return play_game()
if guess < number:
print("Too low.")
elif guess > number:
print("Too high.")
elif guess == number:
print("You won! You guessed it in " + str(count) + " tries.\n")
return
count+=1
play_game()
The issue I'm currently running into is when it checks to see if their guess was between 1-100 instead of moving on to weather or not their number was too how or to low, it stays and loops.
If anyone could help me with this issue and review the code in general I'd appreciate it.
I think the problem is with some indentation and some logical problems in the flow.
When you call play_game() from inside the game, it starts a completely different game
with different random_number.
A good code that satisfies your condition might look like the following
import random
def play_game():
number = random.randint(1, 100)
print("Guess a number between 1 and 100 inclusive.")
count = 1
while True:
guess = int(input("Your guess: "))
if guess > 0 and guess <= 100:
if guess < number:
print("Too low.")
elif guess > number:
print("Too high.")
elif guess == number:
print("You won! You guessed it in " + str(count) + " tries.\n")
return
count+=1
else:
print("Invalid number.")
play_game()
You could re-adjust your code:
1. if no. within range, run your high, low, match checks
2. break if guess matches the no
import random
def play_game():
number = random.randint(1, 100)
print("Guess a number between 1 and 100 inclusive.")
count = 0
while True:
count += 1
guess = int(input("Your guess: "))
if guess > 0 and guess <= 100:
#the age is valid
if guess < number:
print("Too low.")
elif guess > number:
print("Too high.")
elif guess == number:
print("You won! You guessed it in " + str(count) + " tries.\n")
break
else:
print("Invalid number, try again")
play_game()
The issue you are running into is because of incorrect indentation. The if-else statements that check whether the number is within the valid range are at the same indentation level as the while loop and thus are not executed within it. Simply indenting should fix the problem.
Furthermore, you have called play_game without parenthesis, making it incorrect syntax for a function call. However, rather than checking if the number is greater than 0 and lesser than 100, it would more optimal to check whether number is lesser than 0 or greater than 100, and if that is the case, print invalid number and call play_game().
It would look something like this:
while True:
if guess < 0 and guess > 100:
print ("Invalid number.")
return play_game()
The rest of your code looks good. I've also attached the link on the section of indentations of the Python documentation here.

How do I prevent a user from entering a previous guess in my python guessing game? [duplicate]

This question already has answers here:
Asking the user for input until they give a valid response
(22 answers)
Closed 3 years ago.
I want to store a list of guesses the user has already made, so that when the user makes the next guess I can check that guess against a list of previous guesses. If the guess the user just made is in that list I want to tell the user to guess again and not count it as a attempt(5 attempts at guessing correct number)
tried using the append method to append the guesses to a blank list but I'm getting a "int obj has no append method" error.
import random
def guess_a_number():
chances = 5
random_number_generation = random.randint(1,21)
while chances != 0:
choice = int(input("Guess a number between 1-20, you only have {} chances left ".format(chances)))
if choice > random_number_generation:
print("Your number is too high, guess lower")
elif choice < random_number_generation:
print("Your number is too low, guess higher")
else:
print("You guessed the correct number!!!")
break
chances -= 1
if chances == 0:
try_again = input("Do you want to try play again? ")
if try_again.lower() == "yes":
guess_a_number()
else:
print("Better luck next time")
guess_a_number()
Try keeping a list of previous guesses and then check if guess in previous_guesses: immediately after the choice. You can use continue to skip the rest and prompt them again.
Just use a set or a list to hold the previously attempted numbers and check for those in the loop.
I think you already tried something similar but by the sound of it you were attempting to append to an int.
import random
while True:
chances = 5
randnum = random.randint(1, 21)
prev_guesses = set()
print("Guess a number between 1-20, you have {} chances ".format(chances))
while True:
try:
choice = int(input("what is your guess? "))
except ValueError:
print('enter a valid integer')
continue
if choice in prev_guesses:
print('you already tried {}'.format(choice))
continue
if choice > randnum:
print("Your number is too high, guess lower")
elif choice < randnum:
print("Your number is too low, guess higher")
else:
print("You guessed the correct number!!!")
break
chances -= 1
prev_guesses.add(choice)
print("you have {} chances left".format(chances))
if chances == 0:
print("You ran out of guesses, it was {}".format(randnum))
break
try_again = input("Do you want to play again? ")
if try_again.lower() not in ("y", "yes"):
print("Better luck next time")
break

Python: why is my print statement not running for my else?

import random
number = random.randint(0,10)
#print (number)
guess = int(input("I'm thinking of a number between 1 and 10. \nPlease guess what it is: "))
#print(guess)
while guess != number:
if guess > number:
print("That is too high!")
guess = int(input())
elif guess < number:
print("That is too low")
guess = int(input())
else:
print("Thats it! You win!")
I'm working out a few python coding examples and I am confused why my else statement isn't printing?
The code objective is to generate a random number, and then have the user input a guess and then depending if the guess is lower or higher than the random number for the computer to notify the user and if the user guess correctly, then to tell the user that they won.
I'm tested this out and when I input the correct number the code just ends and doesn't print out "That's it! You win!". Why is this and how can I get it to print it out?
Guess input prior to the loop will most times be different than the number to guess, therefore the loop will not enter.
You also have other more subtle bugs: for instance, input is taken twice in one loop, creating conditions for improper feedback. Further, your win is confirmed by default, that is if guess not too high, and if guess not too low, then it is a win; a positive assertion such as if guess equals number, is probably safer to declare a win.
Here is a design that segregates each actions in one place in the loop, minimizing the risks of a faulty logic.
import random
number = random.randint(0, 10)
guess = None
while guess != number:
guess = int(input())
if guess > number:
print("That is too high!")
elif guess < number:
print("That is too low")
elif guess == number:
print("Thats it! You win!")
else:
print('that was not supposed to happen')

Guess the Number Game with Different Guess Names

This is my first time visiting using stackoverflow--I'm new to programming and am taking a beginner's course for Python. Excited to get started!
Our second assignment asks us to create the well-known Guess the Number Game. For those of you who already know this game, I would love some help on an extra piece that's been added to it: we must list off each guess with their respective order. A sample output should look like this:
I'm thinking of an integer, you have three guesses.
Guess 1: Please enter an integer between 1 and 10: 4
Your guess is too small.
Guess 2: Please enter an integer between 1 and 10: 8
Your guess is too big.
Guess 3: Please enter an integer between 1 and 10: 7
Too bad. The number is: 5
I've got the coding down to where I have Guess 1 and Guess 3 appear, but I cannot make Guess 2 appear. I've been reworking and replacing every "while", "if", "elif", and "else" command to fix this, but can't seem to come up with a solution! Here is my code so far:
def guess():
print ("I'm thinking of an integer, you have three guesses.")
attempts = 0
from random import randint
number = randint(0,10)
guess = eval(input("Guess 1: Please enter an integer between 1 and 10: "))
while guess != number and attempts == 0:
if guess < number:
print("Your guess is too small.")
break
if guess > number:
print("Your guess is too big.")
break
elif guess == number:
print("You got it!")
attempts = attempts + 1
if number != guess and attempts == 1:
guess = eval(input("Guess 2: Please enter an integer between 1 and 10: "))
if guess < number:
print("Your guess is too small.")
elif guess > number:
print("Your guess is too big.")
while guess == number:
print("You got it!")
attempts = attempts + 1
elif number != guess and attempts == 2:
guess = eval(input("Guess 3: Please enter an integer between 1 and 10: "))
if guess < number:
print("Too bad. The number is: ", number)
elif guess > number:
print("Too bad. The number is: ", number)
while guess == number:
print("You got it!")
This code outputs Guess 1 and then quits. Can anyone help me figure out how to make Guess 2 and 3 appear?? All ideas are welcome--Thanks!
You can shorten you code quite a bit, just move the input in the loop and keep looping for either three attempts using range or the user guesses correctly:
def guess():
print ("I'm thinking of an integer, you have three guesses.")
from random import randint
number = randint(0,10)
# loop three times to give at most three attempts
for attempt in range(3):
# cast to int, don't use eval
guess = int(input("Guess 1: Please enter an integer between 1 and 10: "))
if guess < number:
print("Your guess is too small.")
elif guess > number:
print("Your guess is too big.")
else: # not higher or lower so must be the number
print("You got it!")
break
It would be better to use a while with a try/except to verify the user inputs a number, looping until the user has used 3 attempts or guesses correctly:
def guess():
print ("I'm thinking of an integer, you have three guesses.")
attempts = 0
from random import randint
number = randint(0,10)
while attempts < 3:
try:
guess =int(input("Guess 1: Please enter an integer between 1 and 10: "))
except ValueError:
print("That is not a number")
continue
if guess < number:
print("Your guess is too small.")
attempts += 1
elif guess > number:
print("Your guess is too big.")
attempts += 1
else: # if it is a number and not too high or low it must be correct
print("You got it!")
break # break the loop
You cannot just use an if/else if you actually want to give the user feedback on whether their guess was too low or too high.
Also as commented don't use eval. Some good reason why are outlined here
All your while guess!=number and attempts == loops are useless, because you're either breaking out of them or incrementing attempts so their condition evaluates to False after the first iteration.
Guess 2 is never reached because either number equals guess (so number != guess is False) or attempts is still zero.
Guess 3 is never reached for the same reason. However, if guess 2 would be reached, guess 3 would never be reached because you put elif in front.
Try to get rid of the code for guess 2 and guess 3. Write all the code for guess = eval(input()) and if guess < number: ... elif guess > number: ... once and put it inside a loop. Here's a bit of pseudocode to illustrate the idea:
while attempts < 3
ask for user input
if guess equals number
print "you win"
exit the loop
else
print "that's wrong"
I used the "concatenation" method along with some of your helpful response ideas and finally got my code to work!! Thank you all so, so much for the help!! Here is the correct code for this program:
def guess():
from random import randint
number = randint(0,10)
print("I'm thinking of an integer, you have three guesses.")
attempts = 0
while attempts < 2:
guess = eval(input("Guess " + str(attempts + 1) + ": Please enter an integer between 1 and 10: "))
if guess < number:
print("Your guess is too small.")
attempts += 1
elif guess > number:
print("Your guess is too big.")
attempts += 1
else:
print("You got it!")
break
else:
attempts == 3
guess = eval(input("Guess 3: Please enter an integer between 1 and 10: "))
if guess < number:
print("Too bad. The number is: ", number)
elif guess > number:
print("Too bad. The number is: ", number)
else:
print("You got it!")
And then ending it with a call to function ("guess()"). Hope this serves well for those who experience this problem in the future. Again, thank you guys!
