In this article, we will discuss how to write a program for guessing the number game.
Outline
Our program will ask the user to guess a number between 1-10(both included). We will give 3 chances to guess. Afterward, we can ask y=the user if they want to continue the game and proceed according to the user’s choice.
Algorithm
- Import the random module.
- Print the welcome message for the game.
- Assign a random number with the help of the randint function to an answer variable.
- Initialize the value of lives to be 3 and answer_list to be empty.
- Get a number from the user and check the following conditions. If the user guessed,
- If the answer is correct, display that you thought it right and break the loop.
- A number that is already available in the answer_list, you can display “You already guessed the same number!!!”.
- A number below 1 or above 10, display that it is not in the specified range.
- If none of the above conditions satisfies, which means you have guessed a number within the range but not the correct answer. We need to append the user’s answer to answer_list. So we can decrement the life and display that it was a wrong answer.
- If the number of life is not equal to 0 we can display the number of lives left. And repeat step 5.
- If the number of lives is 0 we need to display the game over and also display the answer.
- Ask the user if they want to continue playing the game.
- If yes, repeat steps 3 to 6.
- If not, you can display thank you message and come out of the code.
Program with explanation in comments
import random #Importing a module called as random
print("Welcome to guess the number game!!!")
while True: #creates an infinite loop
ans=random.randint(1,10) #getting a random number with the help of randint function and assign it to a variable.
print("\n\n\nYou have three chances to guess the number.")
lives=3 #initialising the lives to be 3
answer_list=[] #Empty list creation
while lives>0: #creates a loop which runs till the lives becomes 0
user_guess=int(input("Guess a number between 1-10 (1 and 10 included) : ")) #getting the user's guess
if ans==user_guess:
#checks for correct answer
print("Wow you gessed it right!!!")
break #breaking the inner loop as the user guessed the answer correctly
elif user_guess in answer_list:
#checks if the user has already guessed the same number.
print("You already guessed the same number!!!")
elif user_guess<1 or user_guess>10:
#checkes if the user guessed the number out of range.
print("Ohho your guess is not within the range just guess between 1-10.")
else:
#control comes here if the user has put a valid input but not the correct answer
lives-=1#decrementing the life
answer_list.append(user_guess)#append the valid guess for future check
if lives!=0:
#if some life is left display the life and proceed the inner loop
print("You guessed it wrong! you still have",lives,"left")
else:
#if no life is left display game over
print("Game over.\nThe number was",ans)
do_you=input("Do You want to play again???\nType 'yes' to continue and 'no' to stop: ").lower()#checks if user wants to continue or quit.
if do_you=="yes":
#continue the outer loop if the user said yes.
continue
else:
# break the outer loop as the user wants to quit.
print("Thank you for playing!!!")
break
Please note:
- If there is more than 1 loop and if we write the break statement it will break only the one loop where it is located. It will not break from all the loops.
- The lower() method converts the input given by the user to lowercase.
