如何添加元组并打印出来？ [复制]

Question

您将如何实现元组的添加，以便对于每个不正确的答案，它将答案添加到元组并打印出来供用户检查和查看他们之前的猜测？我尝试了多种方法，但它们仅用于替换元组中的单词。

import random    

words = ("blueberries", "intelligence", "reactor", "thorns", "nightmare",
         "scars", "metal", "coronavirus", "industries", "heart", "workshop",
         "assistant", "bots")

variable = random.choice(words)    
beg = variable[:1]    
end = variable[-1:]    
length = len(variable)

name = input("Hello USER. Please input your name into the console.")

print("Hello " + name + ". Today, we will be playing a word guessing game. I will be giving you the first and last letter along with the length of the word. You must guess what the word is based on these clues.")

print("1st Letter: " + beg)
print("Last Letter: " + end)
print("Length of word: " + str(length))

guess = input("What is your guess?")

while variable != guess:
    if guess != variable:
        guess = input("Your answer is incorrect. Please try again.")
    elif guess == variable:
        break

print("Congratulations, you have guessed correctly.")

Answer 1

我认为使用list 是更好的选择。因为元组是不可变的。这意味着要将项目添加到元组，您应该创建一个新元组。但列表更具动态性，您可以更简单、更好地向列表中添加项目。 所以你可以使用下面的代码：

previous_choices = []
# Other codes
    if guess != variable:
        previous_choices.append(guess)    
        print(previous_choices)

但是如果你因为某些原因想使用元组，你可以使用下面的代码：

previous_choices = tuple()
# Other codes
    if guess != variable:
        previous_choices += (guess,)  # In fact, every time a new tuple creates here.  
        print(previous_choices)

另外，我认为最好改变获取第一个和最后一个字符的方式。您可以简单地将variable[0] 用于您的beg 变量，并将variable[-1] 用于您的end 变量。

Answer 2

您不需要添加错误的猜测，但您需要将它们连接起来。为此，我初始化了一个列表，然后在该列表中附加了错误的猜测，因为元组是不可变的。但是，如果您需要元组中的结果，那么最后您可以将列表转换为元组。我对代码做了一些更改。请检查一下。

words = ("blueberries", "intelligence", "reactor", "thorns", "nightmare", "scars", "metal", "coronavirus", "industries", "heart", "workshop", "assistant", "bots")

import random

variable = random.choice(words)

beg = variable[:1]

end = variable[-1:]

length = len(variable)

name = input("Hello USER. Please input your name into the console.")

print("Hello " + name + ". Today, we will be playing a word guessing game. I will be giving you the first and last letter along with the length of the word. You must guess what the word is based on these clues.")

print("1st Letter: " + beg)

print("Last Letter: " + end)

print("Length of word: " + str(length))

guess = input("What is your guess?")
wrong_guess=[]
while variable != guess:
  if guess != variable:
    wrong_guess.append(guess)
    guess = input("Your answer is incorrect. Please try again.")
    print("wrong guesses till now are:",wrong_guess)
  elif guess == variable:
    break

print("Congratulations, you have guessed correctly.")
