4 位数字猜谜游戏 Python

Question

我正在尝试在 Python 3 中制作一个 4 位数字猜谜游戏。它应该通过生成一个 1000 到 10000 (random.range(1000,10000)) 之间的随机数然后由用户猜测它应该在每次猜测后返回如何很多数字你都猜对了。 我的代码并不完全有效，我想不通为什么它没有那么帮助表示赞赏。

import random as r

guessing = True
real_ans = r.randrange(1000, 10000, 2)
real_ans_str = str(real_ans)

correct = 0

class Player():
    def __init__(self):
        self.player_guess = input("Enter a guess")
        self.evaluate(correct)
    def evaluate(self, correct):
        for n in range(3):
            if self.player_guess[n] == real_ans_str[n]:
                correct += 1
        if not correct == 4:
            print(str(correct)," was correct")
            correct = 0
        else:
            print("You guessed it! ")
            guessing = False

while guessing:
    Player()

Answer 1

您的代码中有几个问题：

1. 您正在主循环内创建 Player 类的新实例。 它有效，但恕我直言，这不是最好的方法。

2. 您正在使用guessing来停止主循环。 在 Python 中，默认情况下所有变量都是本地变量。 为了引用全局变量，您必须将其标识为全局变量：

def evaluate(self, correct):
    **global guessing**
    for n in range(3):
        if self.player_guess[n] == real_ans_str[n]:
            correct += 1
    if not correct == 4:
        print(str(correct)," was correct")
        correct = 0
    else:
        print("You guessed it! ")
        guessing = False

但是，使用全局变量可能会导致代码混乱。

3. range 提供包含最小值（默认为 0）和不包含最大值的值。 该 range(3) 将提供数字 0、1 和 2（总共 3 个数字），这不是您想要的。

由于您正在使用课程，我会尝试以下操作：

1. 创建 Player 的单个实例

2. 创建一个名为 guess 的新方法

3. 更改评估方法以返回玩家猜对的数字

4. 创建一个名为 run 的新方法，该方法将调用 guess 和评估

import random as r

class Player():
    def __init__(self):
        self.real_ans = str(r.randrange(1000,100000,2))

    def guess(self):
        self.player_guess = raw_input("Enter a guess")

    def evaluate(self):
        correct = 0
        for n in range(4):
            if self.player_guess[n] == self.real_ans[n]:
                correct += 1
        return correct 

    def run(self):
        while True:
            self.guess()
            correct = self.evaluate()
            if not correct == 4:
                print(str(correct)," was correct")
            else:
                print("You guessed it! ")
                break

Player().run()

#Digit Guessing Game by Deniz
#python 3.5.1 - Please note that from Python version 2.7 "Tkinter" has been renamed tkinter, with a lowercase "t".
import tkinter
import random

computer_guess = random.randint(1,10)

def check():

    user_guess = int(txt_guess.get())


if user_guess < computer_guess:
    msg = "Higher!"
elif user_guess > computer_guess:
    msg = "Lower!"
elif user_guess == computer_guess:
    msg = "Correct!"
else:
    msg = "Houston we have a problem!..."


lbl_result["text"] = msg


txt_guess.delete(0, 5)

def reset():

    global computer_guess
    computer_guess = random.randint(1,10)
    lbl_result["text"] = "Game reset. Guess again!"

root = tkinter.Tk()

root.configure(bg="white")

root.title("Guess the correct number!")

root.geometry("280x75")

lbl_title = tkinter.Label(root, text="Welcome to Deniz's guessing Game!", bg="White")
lbl_title.pack()

lbl_result = tkinter.Label(root, text="Good Luck!", bg="White")
lbl_result.pack()

btn_check = tkinter.Button(root, text="Check", fg="blue", bg="White", command=check)
btn_check.pack(side="left")

btn_reset = tkinter.Button(root, text="Reset", fg="red", bg="White", command=reset)
btn_reset.pack(side="right")

txt_guess = tkinter.Entry(root, width=7)
txt_guess.pack()

root.mainloop()
root.destroy()

Answer 3

使用range(4) ， range(3)的值是[0, 1, 2]所以缺少3 ：

for n in range(4):
    if self.player_guess[n] == real_ans_str[n]:
        correct += 1

全局guessing在类方法中不可用，因此在猜测正确后循环永远不会结束。

工作但丑陋的解决方案是：

print("You guessed it! ")
global guessing
guessing = False

Answer 4

阅读您的评论后，我认为您需要的是：

class Player():
    def __init__(self):
        self.player_guess = input("Enter a guess")
        self.evaluate(correct)
    def evaluate(self, correct):
        for n in range(4):
            if self.player_guess[n] == real_ans_str[n]:
                correct += 1
            else:
               print(str(correct)," was correct")
               correct = 0
               break
        if correct == 4:
            print("You guessed it! ")
            guessing = False

您可以将它与@Robson 的答案结合起来以结束循环。

Answer 5

这是一个没有类的非无限循环版本。 我假设你想一次输入一个数字？ 如果没有，那可以改变。

此外， randrange数末尾的 2 只包含偶数，因此没有必要

import random as r
debug = True

real_ans = str(r.randrange(1000, 10000))

if debug:
    print(real_ans) 

correct = 0
for i in range(len(real_ans)):
    player_guess = input("Enter a guess: ")
    if str(player_guess) == real_ans[i]:
        correct += 1

if correct == 4:
    print('You guessed it!')
    correct = 0
else:
    print('Sorry!', real_ans, 'was correct')

样品运行（正确）

9692
Enter a guess: 9
Enter a guess: 6
Enter a guess: 9
Enter a guess: 2
You guessed it!

样品运行（不正确）

4667
Enter a guess: 5
Enter a guess: 5
Enter a guess: 5
Enter a guess: 5
Sorry! 4667 was correct

我所做的只是将第 14 行中的n从n in range(3)中的n in range(4)更改为n in range(4)中的n in range(4)

import random as r

guessing = True
real_ans = r.randrange(1000, 10000, 2)
real_ans_str = str(real_ans)

correct = 0

class Player():
    def __init__(self):
        self.player_guess = input("Enter a guess")
        self.evaluate(correct)
    def evaluate(self, correct):
        for n in range(4):
            if self.player_guess[n] == real_ans_str[n]:
                correct += 1
        if not correct == 4:
            print(str(correct)," was correct")
            correct = 0
        else:
            print("You guessed it! ")
            guessing = False

while guessing:
    Player()
