Today we’ll be creating a guessing number game in Python that you can run in your terminal. Open up your favorite text editor and let’s begin!
To start, we’ll need to
import random as the random module will let us generate a random number for the user to guess.
Then, we’ll set three variables:
numberofGuesses: set to 0 - contains how many guesses the user takes
number: to generate the random number
name: set to
raw_inputto get user’s name
number variable will be set to
random.randint(1,50). This assigns the variable to a random integer between 1 and 50. You may change the range
if you wish.
Here’s what our code should look like so far:
import random numberofGuesses = 0 number = random.randint(1,50) name = raw_input("Hello! What is your name? ")
Now, let’s print a message to the user asking to guess a number between 1 and 50. After that, we can run more
raw_inputs as guesses and calculate whether the guess was too high or low in a while loop with if statements.
Our while loop will run the functions in it until a certain number of guesses. In this case the while loop will be set to
while numberofGuesses < 8:.
In the while loop, we can do the following:
raw_inputfor the guess
guessinput into an integer
1) to the variable of
guessesLeftvariable to 8 -
ifstatements to see if guess is larger or smaller than number
guessesLeftto a string and print out if number is to low/high
guess===number, which breaks the loop if true and prints out that you guessed the number in
guess!=number(not equal), which prints out the
numberthat the computer generated as the user did not guess it within 8 tries
That may seem like a lot - and it is!
import random numberofGuesses = 0 number = random.randint(1,50) name = raw_input("Hello! What is your name? ") print(name + ", I am thinking of a whole number between 1 and 50. Can you guess what it is?") while numberofGuesses < 8: guess = raw_input("Take a guess ") guess = int(guess) numberofGuesses = numberofGuesses + 1; guessesLeft = 8 - numberofGuesses; if guess < number: guessesLeft=str(guessesLeft) print("Your guess is too low! You have " + guessesLeft + " guesses left") if guess > number: guessesLeft=str(guessesLeft) print("Your guess is too high! You have " + guessesLeft + " guesses left") if guess==number: break if guess==number: numberofGuesses=str(numberofGuesses) print("Good job! You guessed the number in " + numberofGuesses + " tries :)") if guess!=number: number=str(number) print("Sorry. The number I was thinking of was " + number + " :)")
Take note that when we want to either use the number in code our print it out, we need to convert it. First, we convert it to an integer (
int(guess)). In the same way, when we want to print out a number, we make sure it is converted to a string (
