I'm getting this error with refrenced before assignment and im not sure how to fix it.
I havent tried anything at the moment. It would be appreciated if this could be answered. (im just trying to fill up more words so it can be posted)
this is the error code i am getting:
number = int(number)
UnboundLocalError: local variable 'number' referenced before assignment
And this is the rest of my code

In your code you are getting level as input and checking that if level is in between 1 to 5.
else you are trying number = int(number)
but you should write number = int(level).
Since level is a string rather than a number, none of the conditions like
if level == 1:
will succeed. So none of the assignments like number = random.randint (1, 16) ever execute, and number is never assigned.
Since if level == 5: doesn't succeed, it goes into the else: block, which starts with
number = int(number)
Since none of the other number assignments took place, this tries to use int(number) before the variable has been assigned, which doesn't work.
I'm not sure why you even have this assignment there. When number is assigned, it's always set to an integer, so there's no need to use int(number).
You need to use
level = int(level)`
after you confirm that it contains digits. And you need to do similarly with again.
There are a number of other problems with your code. For instance, the code that asks for the user's guess and checks it is inside the if level == 5: block, it should run in all the levels.
When you have a series of mutually exclusive tests, you should use elif for each successive test. If you just use if for each of them, and then use else: at the end, that else: will only apply to the last test, so it will be executed even if one of the early tests also succeeded.

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:

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.
Below is my code to generate random number between 0 - 9 and checking with user input whether it is higher lower or equal. When I run the code, it is not taking input and showing
error in 'guessNumber = int(input("Guess a Random number between 0-9")) File "", line 1 '
Can somebody please tell me where I'm making mistake
#Guess Random Number
#Generate a Random number between 0 to 9
import random
turn = 0
def guessRandom():
secretNumber = random.randint(0,9)
guessNumber = int(input("Guess a Random number between 0-9"))
while secretNumber != guessNumber:
if(secretNumber > guessNumber):
input("You have Guessed the number higher than secretNumber. Guess Again!")
turn = turn + 1
elif (secretNumber < guessNumber):
input("You have guessed the number lower than secretNumber. Guess Again! ")
turn = turn + 1
if(secretNumber == guessNumber):
print("you Have Guessed it Right!")
guessRandom()
I think guessRandom() was meant to be outside of the method definition, in order to call the method. The guessNumber variable never changes since the inputs are not assigned to be guessNumber, thus it will continuously check the initial guess. Also, the less than / greater than signs seem to conflict with the intended message. Additionally, turn is outside of the scope of the method.
#Generate a Random number between 0 to 9
import random
def guessRandom():
secretNumber = random.randint(0, 9)
guessNumber = int(input("Guess a Random number between 0-9: "))
i = 0
while secretNumber != guessNumber:
if secretNumber < guessNumber:
print "You have guessed a number higher than secretNumber."
i += 1
elif secretNumber > guessNumber:
print "You have guessed a number lower than secretNumber."
i += 1
else:
print("you Have Guessed it Right!")
guessNumber = int(input("Guess Again! "))
return i
turn = 0
turn += guessRandom()
EDIT: Assuming you're using input in Python3 (or using raw_input in older versions of Python), you may want to except for ValueError in case someone enters a string. For instance,
#Generate a Random number between 0 to 9
import random
def guessRandom():
secretNumber = random.randint(0, 9)
guessNumber = input("Guess a Random number between 0-9: ")
i = 0
while True:
try:
guessNumber = int(guessNumber)
except ValueError:
pass
else:
if secretNumber < guessNumber:
print "You have guessed a number higher than secretNumber."
i += 1
elif secretNumber > guessNumber:
print "You have guessed a number lower than secretNumber."
i += 1
else:
print("you Have Guessed it Right!")
break
guessNumber = input("Guess Again! ")
return i
turn = 0
turn += guessRandom()
I changed the while loop condition to True and added a break because otherwise it would loop indefinitely (comparing an integer to a string input value).
I'm updating a crack the code game I made in Python so that you can play a single-player game against the computer. For some reason, the interpreter either doesn't use the data stripped from the input used to determine player count or skips the if statement that uses the stripped data from the input. Either way, after you input the player number it goes straight to the guessing code with an empty list of correct code characters.
My code for the player count determining and code creation is:
plyrs = 0
correctanswer = []
print('Welcome!')
plyrs = str(input('How many players are there? (minimum 1, maximum 2) '))
if plyrs == 2:
print("I'm gonna ask you for some alphanumerical (number or letter characters to make a code for the other player to guess.")
input('Press enter when you are ready to enter in the code!') #Like all of my games, it has a wait.
i = 0
while i < 4:
correctanswer.append(input('What would you like digit ' + str(i + 1) + " to be? "))
i = i + 1
print("Ok, you've got your code!")
i = 0
while i < 19: #Generates seperator to prevent cheating
print('')
i = i + 0.1
print("Now, it's the other player's turn to guess!")
elif plyrs == 1:
import random
characters = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','1','2','3','4','5','6','7','8','9','0']
i = 0
while i < 4:
correctanswer.append(characters[randint(0,36)])
i = i + 1
print('Time for you to guess!')
print('')
No other skipping if statement questions apply to this so please help.
plyrs is a string, and you're comparing it to an int. "2" == 2 will always be false. Same with plyrs == 1, this will be false throughout.
I am relatively new to programming with python (actually programming in general). I am making this 'Guess My Age' program that only has one problem:
import random
import time
import sys
print("\tAge Guesser!")
print("\t8 tries only!")
name = input("\nWhat's your name? ")
num = 80
min_num = 6
tries = 1
number = random.randint(min_num, num)
print("\nLet me guess... You are", number, "years old?")
guess = input("'Higher', 'Lower', or was it 'Correct'? ")
guess = guess.lower()
while guess != "correct":
if tries == 8:
print("\n I guess I couldn't guess your age....")
print("Closing...")
time.sleep(5)
sys.exit()
elif guess == "higher":
print("Let me think...")
min_num = number + 1 #### Here is my trouble - Don't know how to limit max number
time.sleep(3) # pause
elif guess == "lower":
print("Let me think...")
num = number - 1
time.sleep(3) # pause
number = random.randint(min_num, num) #<- Picks new random number
print("\nLet me guess... You are", number, "years old?")
guess = input("'Higher', 'Lower', or was it 'Correct'? ")
guess = guess.lower() #<- Lowercases
tries += 1 #<- Ups the tries by one
print("\nPfft. Knew it all along.")
time.sleep(10)
As you can see, I have 'num' as the max number for the random integer getting picked, but with:
elif guess == "higher":
print("Let me think...")
min_num = number + 1
it can go back up to however high it wants.
I want it to remember the last integer that 'num' was.
Say the program guessed 50 and I said 'Lower'. Then it said 30 and I said 'Higher'
I know I am probably sounding confusing, but please bear with me.
You need to define a maximum number as well as a minimum number. If they say their age is lower than a given age, you should set that age minus 1 as the maximum.
Of course, you also need to set an initial maximal age.
You might find it more useful to look into recursive functions for this kind of problem. If you define a function which takes min_age, max_age and tries_left as parameters, which comes up with a random number with between min_age and max_age and queries the user, you can then rerun the function (within itself) with a modified min_age, max_age and tries_left - 1. If tries_left is zero, concede defeat. This way you might get a better understanding of the logical flow.
I have left code out of this answer because, as you are a beginner, you will find it a useful exercise to implement yourself.
Cant you split out your guess into something like
max_num = 0
min_num = 0
elif guess =="lower":
max_num = number
if min_num!=0:
number = min_num+(max_num-min_num)/2
else:
number = max_num-1
elif guess =="higher":
min_num = number
if max_num!=0:
number=min_num+(max_num-min_num)/2
else:
number=min_num+1
Sorry it's not meant to be fully rigorous, and its a slight change on the logic you have there, but splitting out your variables so you have a higher and lower cap, that should help a lot?
Cheers
Please let me know if you need more elaboration, and I can try to write out a fully comprehensive version
It seems as though I was wrong in the fact that it did not remember the older integers. Before when running the program it would guess a number higher than the 'num' had specified. I don't know what I changed between then and now? But thank you for the help! #.#
This seems to work.
The only changes I really made:
-Variable names were confusing me, so I changed a couple.
-Note that if you try to mess with it (lower than 5, higher than 3... "Is it 4?" if you say it's higher or lower, you'll get an error).
The first time you set min and max numbers, you do it outside of the loop, so this script does "remember" the last guess and applies it to the new min, max inside of the loop. Each time it runs, the min will get higher or the max will get lower, based on the feedback from when the user checks the guess. If you had stuck the "min_num=6" and the "num=80" inside of the loop, the guesses would never get better.
import random
import time
import sys
print("\tAge Guesser!")
print("\t8 tries only!")
name = input("\nWhat's your name? ")
max_num = 10
min_num = 1
tries = 1
guess = random.randint(min_num, max_num)
print("\nLet me guess... You are", guess, "years old?")
check = raw_input("'Higher', 'Lower', or was it 'Correct'? ")
check = check.lower()
while check != "correct":
if tries == 8:
print("\n I guess I couldn't guess your age....")
print("Closing...")
time.sleep(5)
sys.exit()
elif check == "higher":
print("Let me think...")
min_num = guess + 1
time.sleep(3) # pause
elif check == "lower":
print("Let me think...")
max_num = guess - 1
time.sleep(3) # pause
guess = random.randint(min_num, max_num) # <- Picks new random number
print("\nLet me guess... You are", guess, "years old?")
check = input("'Higher', 'Lower', or was it 'Correct'? ")
check = check.lower() # <- Lowercases
tries += 1 # <- Ups the tries by one
print("\nPfft. Knew it all along.")

I created a Mastermind code and when I attempt to run it on my Mac it just says "logout". If anyone knows why, that would be extremely helpful! Here is the code:
def masterMind():
number = random.ranint(10000,99999) #the computer chooses 5 random numbers
userGuess = raw_input("Guess my 5 digit password:") #asking the user to input their guess
tries = 10 # telling the computer number of tries the user is allowed
while tries < 0: # 10 attempts is the maximum amount
if number != userGuess: # if the computer's password does not equal the user's guess then it equals to one attempt
tries += 1
userGuess = input("Guess my 5 digit password:")
else: #if the user and the computer's answers align
print "Win: ", userGuess
print number
tries = 10
while tries < 0:
will never enter the loop.
You may want to reverse the sense of the comparison, using > instead.
You'll also need to decrement tries within the loop rather than incrementing it.
more "pythonic" (2.x) way. fixes answers like "00000", fixes int to str compair.
def masterMind():
number = "%05d" % random.randint(0, 99999) #the computer chooses 5 random numbers
for tries in range(10):
user_guess = raw_input("Guess my 5 digit password:") #asking the user to input their guess
if number == user_guess:
print "Win on the %d try" % (tries + 1)
break
print "answer was:", number
