千鋒扣丁學(xué)堂Python培訓(xùn)之開發(fā)一個(gè)簡單猜數(shù)字游戲

今天千鋒扣丁學(xué)堂Python培訓(xùn)老師給大家分享一篇關(guān)于如何利用Python開發(fā)一個(gè)簡單的猜數(shù)字游戲的詳細(xì)介紹，文中通過示例代碼介紹的非常詳細(xì)下面我們一起來看一下吧。

游戲規(guī)則

玩家將猜測一個(gè)數(shù)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(shù)字與實(shí)際數(shù)字相比是“大（high）”還是“小(low)”,如此往復(fù)直到玩家猜對數(shù)字。

準(zhǔn)備好Python3

首先，需要在計(jì)算機(jī)上安裝Python?？梢詮腜ython官網(wǎng)下載并安裝。本教程需要使用最新版的Python3（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(yùn)行該程序。

現(xiàn)在，在設(shè)備上打開文本/代碼編輯器。就個(gè)人而言，我偏好使用Brackets。Windows上預(yù)裝了Notepad，MacOS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(jié)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(xù)到行結(jié)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(nèi)容。

例如，可以將正確的數(shù)字設(shè)置為1到100而不是1到10，可以更改程序在print（）函數(shù)中所說的內(nèi)容。你的代碼想怎么寫都可以。

運(yùn)行程序

根據(jù)你的操作系統(tǒng)，打開命令提示符（Windows/Linux）或終端（Mac）。按順序嘗試以下每個(gè)命令。如果正確安裝Python，其中至少有一個(gè)應(yīng)該可以運(yùn)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(yùn)行后，可測試一下，玩幾次！完成操作后，按向上箭頭鍵復(fù)制最后一個(gè)命令，然后按Enter即可再次運(yùn)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.")
