While loop guessing game python 3

The computer will think of a secret number from 1 to 20 and ask the user to guess it. After each guess, the computer will tell the user whether the number is too high or too low. The user wins if they can guess the number within six tries. This is a good game to code because it covers many programming concepts in a short program.

What is your name? Albert Well, Albert, I am thinking of a number between 1 and Take a guess. You guessed my number in 3 guesses! Open a new file editor window by clicking File New Window. In the blank window that appears, enter the source code and save it as guess.

Then run the program by pressing F5. When you enter this code into the file editor, be sure to pay attention to the spacing at the front of the lines. Some lines need to be indented four or eight spaces. This is a Guess the Number game. The first line is a comment, which you saw in Chapter 2.

Remember that Python will ignore everything after the character. The comment here just reminds us what this program does. The second line is an import statement. While Python includes many built-in functions, some functions are written in separate programs called modules. You can use these functions by importing their modules into your program with an import statement.

Line 2 imports the random module so that the program can call the randint function. This function will come up with a random number for the player to guess. Lines 6 and 7 are the same as the lines in the Hello World program in Chapter 2. Programmers often reuse code from other programs to save themselves work. Line 6 is a function call to print. Remember that a function is like a mini-program inside your program.

When your program calls a function, it runs this mini-program. The code inside print displays the string argument you passed it on the screen. Line 7 lets the player enter their name and stores it in the myName variable. Computers are dumb and follow their instructions, no matter what.Topics Covered In This Chapter:. The computer will think of a random number from 1 to 20, and ask you to guess it.

The computer will tell you if each guess is too high or too low. You win if you can guess the number within six tries. This is a good game to code because it uses random numbers, loops, and input from the user in a short program.

The text that the player types in is in bold. In the blank window that appears, type in the source code and save it as guess. Then run the program by pressing F5. When you enter this code into the file editor, be sure to pay attention to the spacing at the front of some of the lines.

Some lines have four or eight spaces of indentation. The programs in this book will only run on Python 3, not Python 2. If you have Python 2 installed, you can have Python 3 installed at the same time.

The first line is a comment. Remember that Python will ignore everything after the sign. This just reminds us what this program does.

The second line is an import statement. While Python includes many built-in functions, some functions exist in separate programs called modules. You can use these functions by importing their modules into your program with an import statement. Line 2 imports the module named random so that the program can call random. This function will come up with a random number for the user to guess.

Line 4 creates a new variable named guessesTaken. Lines 6 and 7 are the same as the lines in the Hello World program that you saw in Chapter 3. Programmers often reuse code from their other programs to save themselves work. Line 6 is a function call to the print function. Remember that a function is like a mini-program inside your program. When your program calls a function, it runs this mini-program. The code inside the print function displays the string argument you passed it on the screen.

Line 7 lets the user type in their name and stores it in the myName variable. Computers are dumb and just follow their instructions no matter what. Line 9 calls a new function named randint and stores the return value in number.

Remember, function calls can be part of expressions because they evaluate to a value. The randint function is provided by the random module, so you must precede it with random. The randint function will return a random integer between and including the two integer arguments you pass to it.

One way to repeat similar tasks is through using loops. A while loop implements the repeated execution of code based on a given Boolean condition. The code that is in a while block will execute as long as the while statement evaluates to True. You can think of the while loop as a repeating conditional statement.

After an if statement, the program continues to execute code, but in a while loop, the program jumps back to the start of the while statement until the condition is False. The something that is being done will continue to be executed until the condition that is being assessed is no longer true. While going through this loop, there are two possible outcomes:.

Here, the while is followed by the variable password. This means that if the user inputs the string passwordthen the loop will stop and the program will continue to execute any code outside of the loop. However, if the string that the user inputs is not equal to the string passwordthe loop will continue. Inside of the while loop, the program runs a print statement that prompts for the password.

The program will check to see if the variable password is assigned to the string passwordand if it is, the while loop will end. The last print statement is outside of the while loop, so when the user enters password as the password, they will see the final print statement outside of the loop. However, if the user never enters the word passwordthey will never get to the last print statement and will be stuck in an infinite loop.

An infinite loop occurs when a program keeps executing within one loop, never leaving it. Here is sample output from the program:. Keep in mind that strings are case sensitive unless you also use a string function to convert the string to all lower-case for example before checking.

To best understand how this program works, you should also read about using conditional statements and converting data types. At this point, we can get into our while loop, first initializing a variable and then creating the loop. Within the loop, we added a print statement to prompt the user to enter a number, which we took in with the input function and set to the guess variable.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

You follow a lot of standard practices well, so the code is actually quite easy to read, but there are some ways to consolidate a bit that'll make it even simpler.

You while loop while the guess is incorrect, but you also break when the answer is correct, nullifying the need for the condition.

This also has the unintended side effect that, if their answer is correct in their first guess, you never enter the loop, and therefore never congratulate the user for winning.

Let's update the modal for new askers. Hot Network Questions.Hey everyone! Since my last Python 3 Instuctable did really well and got featured, I thought I would show everyone how to code a fun guessing game in Python!

This is my own modified version of a guessing game by Hywel Carver in the book 'Coding Unlocked'. The program generates a random number and asks you for a number.

If the number you choose is lower than the target number, the program will tell you to go a bit higher and ask you to choose again, and vice versa.

When your guess is correct, the program congratulates you and asks if you want to play again. This program is more fun than my other one which was intended for educational use anyway. You'll probably want to keep playing this game if you like guessing games. Let's get right into it! I am not going to explain how to download Python here, as I have already in another Instructable. This code will decide if you have guessed the correct number. Play again? See you next time! The 2nd, 3rd, 4th and 6th line have 12 spaces.

The 5th, 7th and 8th line have 16 spaces at the start. The last part of conditions. This code is pretty much the same as the remainder calculator's: try: guessinggame except: print "Hey, that's not a number! There are four spaces before the 2nd, 4th and 5th lines. Run the program. You should be prompted to guess a number. Type in a number and press enter. If you get it wrong, the program will tell you if you need to type in a higher number or a lower number.

If you get it right, you can choose to play again or exit. If there are any errors, please leave a comment or email me at redking gmail.Help Needed This website is free of annoying ads. We want to keep it like this. You can help with your donation: The need for donations Endless Loops An infinite loop, or a continuous loop, is a sequence of statements in a computer program which loops endlessly. Loops in Music In electronic music, a loop is a sample which is repeated continuously.

Loops may be created by using tape loops, delay effects, sampling, a sampler or special computer software. Nevertheless, it is faster and more efficient to attend a "real" Python course in a classroom, with an experienced trainer. This way you will get a perfect training up to your needs and it will be extremely cost efficient as well. Contact us so we can find the ideal course to meet your needs.

Quote of the Day: "Computer science is no more about computers than astronomy is about telescopes. Many algorithms make it necessary for a programming language to have a construction which makes it possible to carry out a sequence of statements repeatedly.

The code within the loop, i. Python supplies two different kinds of loops: the while loop and the for loop, which correspond to the condition-controlled loop and collection-controlled loop. Most loops contain a counter or more generally, variables, which change their values in the course of calculation. These variables have to be initialized before the loop is started. The counter or other variables, which can be altered in the body of the loop, are contained in the condition.

Before the body of the loop is executed, the condition is evaluated. If it evaluates to False, the while loop is finished. In other words, the program flow will continue with the first statement after the while statement, i.

If the condition is evaluated to True, the body, - the indented block below the line with "while" - gets executed. After the body is finished, the condition will be evaluated again. The body of the loop will be executed as long as the condition yields True. It's best to illustrate the operating principle of a loop with a simple Python example.

The following small script calculates the sum of the numbers from 1 to We will later introduce a more elegant way to do it. Before we go on with the while loop, we want to introduce some fundamental things on standard input and standard output.

Normally, the keyboard serves as the standard input. The standard output is usually the terminal or console where the script had been started, which prints the output.

A script is supposed to send its error messages to the standard error. The following script shows how to read with a while loop character by character from standard input keyboard.

Similar to the if statement, the while loop of Python has also an optional else part.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Cowan Roberts Cowan Roberts 11 1 1 silver badge 2 2 bronze badges. You need to prompt the user again in the while not correct: loop; Eumiro's method is best :. In addition, I think random. I'm not sure if it is; in just the normal object type, range 1, 10 is only 1 to 9; it excludes the second argument.

Ah ok, I wasn't sure if the stop argument was exclusive or not as in a normal range, the stop argument IS exclusive. Active Oldest Votes. You have to ask the user again. I would otherwise follow the improvement proposed by furins. Moving the request inside the while loop does the trick : print ''' This is the guessing game!
