如何使Python 3.4保持猜测的分数？

Question

我正在用Python做一个Guess the Number游戏，我想让Python记分您猜对数字之前花了多少次。 我将如何去做呢？ 如果需要，我可以发布代码进行查看。 谢谢。

Answer 1

@Benjamin的答案会起作用。 但是要回答有关如何开始执行DRY的问题，您可以执行以下操作：

您的整个主要游戏代码都可以进入此功能，并使用一些定义硬度的关键参数：

def the_game(difficulty_name, range_start, range_end):
    score = 0
    print ("")
    print ("Difficulty: %s" % difficulty_name)
    print ("")
    irand = randrange(range_start, range_end)
    with open("GTN.txt", "a") as text_file:
        text_file.write(str(irand) + " %s" % difficulty_name + "\n")
    while True:
        number = input("Pick a number 1 - 10: ")
        try:
            number = int(number)
        except ValueError:
            print("    ")
            print(number, 'is not a number, try again.')
            continue
        if number > irand:
            print("That's too high, try again.")
            print("    ")
            score += 1
            time.sleep(1)
        elif number < irand:
            print("That's too low, try again.")
            print("    ")
            score += 1
            time.sleep(1)
        elif number == irand:
            print("    ")
            print("You got it right! You won!")
            print("    ")
            print("You guessed wrong " + str(score) + " times")
            time.sleep(2)
            main()
            break

然后，您可以定义一些小功能，这些功能可以根据用户选择的硬度级别来调用游戏，如下所示：

#Difficulty - Easy
def easy():
    the_game("Easy", 1, 10)

#Difficulty - Medium       
def medium():
    the_game("Medium", 1, 100)

#Difficulty - Hard
def hard():
    the_game("Hard", 1, 1000)

#Difficulty - Ultra
def ultra():
    the_game("Ultra", 1, 100000)

#Difficulty - Master
def master():
    the_game("Master", 1, 1000000)

最后，您可以像这样定义主要功能：

#This is the MainMenu  
def main():
    time.sleep(2)
    while True:
        print ("Please select a difficulty when prompted!")
        time.sleep(1)
        print ("[1] Easy")
        time.sleep(1)
        print ("[2] Medium")
        time.sleep(1)
        print ("[3] Hard")
        time.sleep(1)
        print ("[4] Ultra")
        time.sleep(1)
        print ("[5] Master")
        time.sleep(1)
        print ("[6] Exit")
        print ("")
        time.sleep(1)
        choice = input ("Please Choose: ")

        def show_loading_screen():
            time.sleep(2)
            print ("")
            print ("Loading game...")
            time.sleep(2)

        def show_exit_screen():
            time.sleep(2)
            print ("")
            print ("Exiting the game!")
            print ("")
            print ("3")
            time.sleep(0.5)
            print ("2")
            time.sleep(0.5)
            print ("1")
            time.sleep(2)

        if choice == '1':
            show_loading_screen()
            easy()

        elif choice == '2':
            show_loading_screen()
            medium()

        elif choice == '3':
            show_loading_screen()
            hard()

        elif choice == '4':
            show_loading_screen()
            ultra()

        elif choice == '5':
            show_loading_screen()
            master()

        elif choice == '6':
            show_exit_screen()
            SystemExit 

        else:
            print ("Invalid Option: Please select from those available.")
            print("")
            time.sleep(1)

您会发现我们已经将重复的屏幕加载代码行提取到内联函数中，可以重复使用。

最后，如果该Python文件作为脚本执行，则可以调用此主要函数。 这是一个好习惯。 您可以这样做：

if __name__ == "__main__":
    print ("Welcome to GTN!")
    time.sleep(2)
    print ("Developed by: oysterDev")
    time.sleep(2)
    print ("Version 1.1.0")
    print ("    ")        
    main()

希望这对了解如何开始对DRY进行重构很有帮助。

Answer 2

尝试制作一个名为ex的变量。 “得分”，每当他们猜错的时候加1。

这应该工作。

def easy():
score = 0
print ("")
print ("Difficulty: Easy")
print ("")
irand = randrange(1,10)
with open("GTN.txt", "a") as text_file:
    text_file.write(str(irand) + " Easy" + "\n")
while True:
    number = input("Pick a number 1 - 10: ")
    try:
        number = int(number)
    except ValueError:
        print("    ")
        print(number, 'is not a number, try again.')
        continue
    if number > irand:
        print("That's too high, try again.")
        print("    ")
        score += 1
        time.sleep(1)
    elif number < irand:
        print("That's too low, try again.")
        print("    ")
        score += 1
        time.sleep(1)
    elif number == irand:
        print("    ")
        print("You got it right! You won!")
        print("    ")
        print("You guessed wrong " + str(score) + " times")
        time.sleep(2)
        main()
        break

希望能帮助到你。
