This is my code, except it doesn't do what I want it to do. After you guess the correct number, it doesn't see to properly loop through the game again when you say yes or no. It just goes through the final if statement again.
Why won't it go through the entire program again?
Your code will always be evaluated to true
if again == "yes" or "YES":
Change it to:
if again.lower() == "yes":
Or
if again in ("YES", "yes", "y",..)
When it is true, you need to break from you second loop:
if again.lower() == "yes":
replay = replay + 1
break
When it is false, don't break but exit the program using:
exit()
Since replay is only used to exit your code, you don't need it if you use exit().
Code would then be:
import random
while True:
target = random.randint(1, 100)
guess = int(input("Guess the number 1-100: "))
score = 0
while True:
score = score + 1
if guess < target:
print ("The number is higher. Try again.")
guess = int(input("Guess the number 1-100: "))
elif guess > target:
print ("The number is lower. Try again.")
guess = int(input("Guess the number 1-100: "))
elif guess == target:
print ("You guessed Correctly!")
print ("Your score was:", score)
again = str(input("Play again? (yes or no)"))
if again.lower() == "yes":
break
elif again.lower() == "no":
exit()

Could you, please, help me to understand how should I use try/except block and count tries at the same time.
Here is the code without try/except block (it seems it's working fine):
import random
number = random.randint(1, 10)
tries = 3
name = input('Hi! What is your name?\n')
answer = input(f'{name}, let\'s play a game! Yes or No?\n')
if answer == 'Yes':
print(f'But be aware: you have only {tries} tries!\nReady?')
chat = input('')
print('Ok, guess a number from 1 to 10!')
while tries != 0:
choice = int(input('Your choice: '))
tries -= 1
if choice > number:
print('My number is less!')
elif choice < number:
print('My number is higher!')
else:
print('Wow! You won!')
break
print(f'You have {tries} tries left.')
if tries == 0 and choice != number:
print(f'Sorry, {name}, you lost... It was {number}. Try next time. Good luck!')
else:
print('No problem! Let\'s make it another time...')
This one is with try/except block.. Not sure where should I place 'choice' variable and where count 'tries', it keeps looping and looping:
import random
number = random.randint(1, 10)
tries = 3
name = input('Hi! What is your name?\n')
answer = input(f'{name}, let\'s play a game! Yes or No?\n')
if answer == 'Yes':
print(f'But be aware: you have only {tries} tries!\nReady?')
chat = input('')
print('Ok, guess a number from 1 to 10!')
while True:
try:
choice = int(input('Your choice: '))
if 0 < choice < 11:
while tries != 0:
tries -= 1
if choice > number:
print(f'My number is less!')
elif choice < number:
print(f'My number is higher!')
else:
print('Wow! You won!')
break
print(f'You have {tries} tries left.')
if tries == 0 and choice != number:
print(f'Sorry, {name}, you lost... It was {number}. Try next time. Good luck!')
else:
print(f'Hey {name}, I said, print a number from 1 to 10!')
except ValueError:
print('Please, enter a number!')
else:
print('No problem! Let\'s make it another time...')
Thanks!
I am trying to make a simple guess the number program in python. When I run this code,an error generates saying that,"local variable 'chance' referenced before assignment". I looked up for a solution on internet but I could not rectify my error. Please help with this problem. How can I use the variable globally which is declared inside a function?
I am beginner in programming, so plese explain in simple words.
Here is the code..
Since I am a beginner,I will be pleased if my code can be rectified
import random
def Random():
chance = 3
number = random.randint(0,20)
return chance
return number
def main():
while chance > 0:
UserInput = int(input('Guess the number: '))
if UserInput == number:
print('You have guesses the secret number!')
elif UserInput > 20 and UserInput < 0:
print('Your guess is out of range!\n Try again!')
else:
chance -= 1
if chance == 1:
print('You are out of chances!')
print('Wrong Guess!\nTry again!')
print(f'You have {chance} chances left!')
Random()
main()
playAgain = input('Want to play again? ')
if playAgain == 'yes' or 'YES' or 'Yeah' or 'yeah':
Random()
main()
else:
print('Thanks for playing!')
You can return a list or a tuple to the outside word:
import random
def example():
chance = 3
number = random.randint(0,20)
return (chance, number) # return both numbers as a tuple
chance, randNr = example() # decomposes the returned tuple
print(chance, randNr)
prints:
3, 17
There are more bugs in your program, f.e.:
if playAgain == 'yes' or 'YES' or 'Yeah' or 'yeah':
is always True and you'll never be able to leave the game. Better would be
if playAgain.lower() in {'yes', 'yeah'}:
etc.
Here is a working example for your programs purpose:
import random
while True:
chances = 3
number = random.randint(0,20)
while chances > 0:
guess = int(input("Guess number: "))
if guess == number:
print("Correct")
break
else:
chances -= 1
print("Wrong, ", chances, " more tries to get it right.")
if chances == 0:
print ("You failed")
if not input("Play again? ")[:1].lower() == "y":
break
print("Bye.")
Read about tuples
Output:
Guess number: 1
Wrong, 2 more tries to get it right.
Guess number: 4
Correct
Play again? y
Guess number: 1
Wrong, 2 more tries to get it right.
Guess number: 2
Wrong, 1 more tries to get it right.
Guess number: 3
Wrong, 0 more tries to get it right.
You failed
Play again? n
Bye.

I'm trying to get a guessing game with the user input as an answer and if the user type exit the game will show the amount of time the player tried but the program won't run because it can only take either interger or string type.
import random
while True:
number = random.randint(1,9)
guess = int(input('guess the number: '))
time = 0
time += 1
if guess == number:
print('you guessed correct')
elif guess < number:
print('your guessed is lower than the actual number')
elif guess > number:
print('your guessed is higher than the actual number')
elif guess == 'exit':
print(time)
break
something like this
import random
time = 0
number = random.randint(1,9)
while True:
guess = input('guess the number: ')
time += 1
if guess == "exit":
print(time)
break
elif int(guess) < number:
print('your guessed is lower than the actual number')
elif int(guess) > number:
print('your guessed is higher than the actual number')
elif int(guess) == number:
print('you guessed correct')
print(time)
break
note that time and number have to be initializate outside the while loop, because if not, we would get different random numbers for each iteration, and also time would be initializate to 0 each time.
You can test the input as a string first before converting it to an integer:
while True:
response = input('guess the number: ')
if response == 'exit':
break
guess = int(response)
# the rest of your code testing guess as a number
I created a simple number guessing game, but every time I don't type in a number the system crashes. Can someone please help!
import random
randNum = random.randint(1, 100)
guesses = 0
for i in range(1, 8):
guesses = guesses + 1
print("hi human guess a number 1-100! \n")
guess = input()
guess = int(guess)
if guess > randNum:
print("your guess is too high")
elif guess < randNum:
print("your guess is too low")
elif guess == randNum:
print("duuude you're a genius \n")
print("you needed " + str(guesses) + " guesses")
I took a quick look at your code and one thing which stands out is that on Line 10, you cast the input to an int without checking if the input is indeed an int.
The system crashes because Python cannot typecast characters to integers when you type cast them. You should explicitly write a condition to check for characters i.e. if the input string is anything except numbers, your code should print something like "Try Again" or "Invalid Input".
import random
randNum = random.randint(1, 100)
guesses = 0
for i in range(1, 8):
guesses = guesses + 1
print("hi human guess a number 1-100! \n")
guess = input()
if guess.isdigit():
if int(guess) > randNum:
print("your guess is too high \n")
elif int(guess) < randNum:
print("your guess is too low \n")
elif int(guess) == randNum:
print("duuude you're a genius \n")
print("you needed " + str(guesses) + " guesses")
else:
print("Invalid Input! Try a number. \n")
Try this code. I hope it helps. And from next time try to upload code instead of images. ;-)

if computer > user:
count += 1
print("You guessed too low!")
print("You have used " + str(count) + "/5 guesses")
user = int(input("Please guess a number another number!: "))
elif computer < user:
count += 1
print("You guessed too high!")
print("You have used " + str(count) + "/5 guesses")
user = int(input("Please guess a number another number: "))

print("Bummer, nice try...the number was actually " + str(computer) + "!")

I created a number guessing game, that is the code:
#Guess the number game
import random
guesses = 6
number = random.randint(0, 100)
win = False
while guesses > 0:
guess = int(input("Guess: "))
guesses -= 1
if guess > number:
print("Your guess is too high", guesses, "remaining")
elif guess < number:
print("Your guess is too low", guesses, "remaining")
elif guess - number < 6:
print("You are very close")
else:
print("Congrats, you guessed")
win = True
guesses = 0
if win == False:
print("Sorry, you didn't guess the number", number)
However, I want it so that if the user inputs a number which is bigger by 5 or lower by 5 than the random number(number variable), to print "You are close".
how about this:
import random
guesses = 6
number = random.randint(0, 100)
win = False
while guesses > 0:
guess = int(input("Guess: "))
guesses -= 1
if guess == number:
win = True
guesses = 0
elif abs(guess - number) < 6:
print("You are very close")
elif guess > number:
print("Your guess is too high", guesses, "remaining")
elif guess < number:
print("Your guess is too low", guesses, "remaining")
if win == False:
print("Sorry, you didn't guess the number", number)
else:
print("Congrats, you guessed correct")
you need to check early if the number is close (before the guess > number checks); and abs is there to accept a difference in both directions
your guess - number < 6 will never be reached; one of the 2 conditions above will already have been met; and without the abs this condition will be true even for very small guesses.
and maybe it would be better to loop over the guesses with a for loop and break if the solution has been found.
