如何使用Python制作一個簡單的猜數字游戲。
游戲規則
玩家將猜測一個數字。如果猜測是正確的,玩家贏。如果不正確,程序會提示玩家所猜的數字與實際數字相比是“大(high)”還是“小(low)”,如此往復直到玩家猜對數字。
準備好Python3
首先,需要在計算機上安裝Python。可以從Python官網下載并安裝。本教程需要使用最新版的Python 3(版本3.x.x)。
確保選中將Python添加到PATH變量的框。如果不這樣做,將很難運行該程序。
現在,在設備上打開文本/代碼編輯器。就個人而言,我偏好使用Brackets。 Windows上預裝了Notepad, Mac OS包含TextEdit,而Linux用戶可以使用Vim。
打開文本編輯器后,保存新文件。我將它命名為main.py,但你可以隨意命名,只要它以.py結尾即可。
編碼
本教程的說明將作為注釋包含在代碼中。 在Python中,注釋以#開頭并一直持續到行結束。
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,可以隨意更改程序中的任何內容。
例如,可以將正確的數字設置為1到100而不是1到10,可以更改程序在print()函數中所說的內容。你的代碼想怎么寫都可以。
運行程序
根據你的操作系統,打開命令提示符(Windows / Linux)或終端(Mac)。 按順序嘗試以下每個命令。 如果正確安裝Python,其中至少有一個應該可以運行。
python C:/Users/username/Desktop/main.py py C:/Users/username/Desktop/main.py python3 C:/Users/username/Desktop/main.py
確保將C:/Users/username/Desktop/main.py替換為Python文件的完整路徑。
程序運行后,可測試一下,玩幾次! 完成操作后,按向上箭頭鍵復制最后一個命令,然后按Enter即可再次運行。
以下是沒有任何注釋的代碼版本:
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.")
