海外TECH	DEV Community	How To Code a Simple Number Guessing Game in Python	https://dev.to/balapriya/how-to-code-a-simple-number-guessing-game-in-python-4jai	How To Code a Simple Number Guessing Game in PythonI spent the last weekend compiling a list of games you can code in Python But why If you re a beginner Python programmer building fun games will help you learn the language fasterーand betterーwithout getting bogged down in the syntax and the like I built some of the games when I was learning Python I quite enjoyed the process The first game you can codeーand the simplest of them allーis a number guessing game or Guess the Number So I thought I d write a step by step tutorial to help beginners learn some of the fundamentals along the way Let s begin How Does the Number Guessing Game Work In a number guessing game the user guesses a randomly generated secret number within a given number of attempts After each guess the user gets hints on whether their guess is too high too low or correct So yeah the game ends when the user guesses the secret number or runs out of attempts Coding the Number Guessing GameLet s get to coding Create a new Python script and code along Step Import the random moduleLet s start by importing the built in random module The random module has functions we can use to generate a random secret number within the specified range import randomNote The random module gives pseudo random numbersーand not truly random numbers So don t use it for sensitive applications such as password generation Step Set up the range and the maximum number of attemptsNext we need to decide on the range for the secret number and the maximum number of attempts allowed for the player For this tutorial let s set the lower bound and upper bound to and respectively Also set the maximum attempts allowed max attempts to lower bound upper bound max attempts Step Generate a random numberNow let s generate a random number within the specified range using the random randint function This is the secret number that the user needs to guess secret number random randint lower bound upper bound Step Read in the user s inputTo get input from the user let s create a function called get guess Remember the user can enter an invalid input a number outside the range lower bound upper bound a string or a floating point number and more We handle this in the get guess function that continuously prompts the user to enter a numberーwithin the specified rangeーuntil they provide a valid input Here we use a while loop to prompt user for a valid input until the player enters a number between lower bound and upper bound def get guess while True try guess int input f Guess a number between lower bound and upper bound if lower bound lt guess lt upper bound return guess else print Invalid input Please enter a number within the specified range except ValueError print Invalid input Please enter a valid number Step Validate the user s guessNext let s define a check guess function that takes the user s guess and the secret number as inputs and provides feedback on whether the guess is correct too high or too low The function compares the player s guess with the secret number and returns a corresponding message def check guess guess secret number if guess secret number return Correct elif guess lt secret number return Too low else return Too high Step Track number of attempts and detect end of game conditionsWe ll now create the function play game that handles the game logic and puts everything together The function uses the attempts variable to keep track of the number of attempts made by the user Within a while loop the user is prompted to enter a guess that s processed by the get guess function The call to the check guess function provides feedback on the user s guess If the guess is correct the user wins and the game ends Otherwise the user is given another chance to guess And this continues until the player guesses the secret number or runs out of attempts Here s the play game function def play game attempts won False while attempts lt max attempts attempts guess get guess result check guess guess secret number if result Correct print f Congratulations You guessed the secret number secret number in attempts attempts won True break else print f result Try again if not won print f Sorry you ran out of attempts The secret number was secret number Step Play the game Finally you can call the play game function every time the Python script is run if name main print Welcome to the Number Guessing Game play game Here s the output from a sample run of the script Welcome to the Number Guessing Game Guess a number between and Too low Try again Guess a number between and Too high Try again Guess a number between and Too low Try again Guess a number between and Too low Try again Guess a number between and Too low Try again Guess a number between and Congratulations You guessed the secret number in attempts Wrapping UpCongratulations You ve successfully built a number guessing game in Python I ll see you all soon in another tutorial But don t wait for me Check out other games you can buildーand features you can codeーand start coding	2023-07-27 02:30:28
