用Python开发一个简单的猜数字游戏

  本文介绍如何使用Python制作一个简单的猜数字游戏。

  游戏规则

  玩家将猜测一个数字。如果猜测是正确的,玩家赢。如果不正确,程序会提示玩家所猜的数字与实际数字相比是“大(high)”还是“小(low)”,如此往复直到玩家猜对数字。

  准备好Python3

  首先,需要在计算机上安装Python。可以从Python官网下载并安装。本教程需要使用最新版的Python 3(版本3.x.x)。

  确保选中将Python添加到PATH变量的框。如果不这样做,将很难运行该程序。

  现在,在设备上打开文本/代码编辑器。就个人而言,我偏好使用Brackets。 Windows上预装了Notepad, Mac OS包含TextEdit,而Linux用户可以使用Vim。

  打开文本编辑器后,保存新文件。我将它命名为main.py,但你可以随意命名,只要它以.py结尾即可。

  编码

  本教程的说明将作为注释包含在代码中。 在Python中,注释以#开头并一直持续到行结束。

用Python开发一个简单的猜数字游戏

  from keras.layers import Conv2D, MaxPooling2D, GlobalAveragePooling2D

  # First, we need to import the 'random' module.

  # This module contains the functionality we need to be able to randomly select the winning number.

  import random

  # Now, we need to select a random number.

  # This line will set the variable 'correct' to be equal to a random integer between 1 and 10.

  correct = random.randint(1, 10)

  # Let's get the user's first guess using the 'input' function.

  guess = input("Enter your guess: ")

  # Right now, the user's input is formatted as a string.

  # We can format it as an integer using the 'int' function.

  guess = int(guess)

  # Let's start a loop that will continue until the user has guessed correctly.

  # We can use the '!=' operator to mean 'not equal'.

  while guess != correct:

  # Everything in this loop will repeat until the user has guessed correctly.

  # Let's start by giving the user feedback on their guess. We can do this using the 'if' statement.

  # This statement will check if a comparison is true.

  # If it is, the code inside the 'if' statement will run.

  if guess > correct:

  # This code will run if the user guessed too high.

  # We can show a message to the user using the 'print' function.

  print("You've guessed too high. Try guessing lower.")

  else:

  # The 'else' statement adds on to an 'if' statement.

  # It will run if the condition of the 'if' statement is false.

  # In this case, it will run if the user guessed too low, so we can give them feedback.

  print("You've guessed too low. Try guessing higher.")

  # Now we need to let the user guess again.

  # Notice how I am combining the two lines of guessing code to make just one line.

  guess = int(input("Enter your guess: "))

  # If a user's guess is still incorrect, the code in the 'while' loop will be repeated.

  # If they've reached this point in the code, it means they guessed correctly, so let's say that.

  print("Congratulations! You've guessed correctly.")

  此外,可以随意更改程序中的任何内容。

  例如,可以将正确的数字设置为1到100而不是1到10,可以更改程序在print()函数中所说的内容。你的代码想怎么写都可以。

  运行程序

  根据你的操作系统,打开命令提示符(Windows / Linux)或终端(Mac)。 按顺序尝试以下每个命令。 如果正确安装Python,其中至少有一个应该可以运行。

  python C:/Users/username/Desktop/main.py

  py C:/Users/username/Desktop/main.py

  python3 C:/Users/username/Desktop/main.py

  确保将C:/Users/username/Desktop/main.py替换为Python文件的完整路径。

  程序运行后,可测试一下,玩几次! 完成操作后,按向上箭头键复制最后一个命令,然后按Enter即可再次运行。

  以下是没有任何注释的代码版本:

  import random

  correct = random.randint(1, 10)

  guess = input("Enter your guess: ")

  guess = int(guess)

  while guess != correct:

  if guess > correct:

  print("You've guessed too high. Try guessing lower.")

  else:

  print("You've guessed too low. Try guessing higher.")

  guess = int(input("Enter your guess: "))

  print("Congratulations! You've guessed correctly.")
