猜數字遊戲python

Question

所以我正在猜測數字遊戲，其中一個要求是爲了更新數字的「範圍」，以便用戶有更輕鬆的時間與他們的猜測。當數字太高或太低時，我創建了一個新的輸入。然而，我並不是很擅長循環，我無法弄清楚爲什麼我的循環只重複一次而沒有反覆粘貼代碼。任何人都可以幫助elif語句重複，直到數字是正確的？

這是我的代碼迄今...

import random 
random_number = random.randint(1,100) 
tries = 0 
while tries < 800: 
    guess = input("Guess a random number between 1 and 100.")  
    tries += 1 
    try: 
    guess_num = int(guess) 
    except: 
    print("That's not a whole number!") 
    break 

    if not guess_num > 0 or not guess_num < 101: 
    print("That number is not between 1 and 100.") 
    break 

    elif guess_num == random_number: 
    print("Congratulations! You are correct!") 
    print("It took you {} tries.".format(tries)) 
    break 

    elif guess_num > random_number: 
     print("Sorry that number is too high.") 
     guess_high = input("Guess a number between 0 and {} .".format(guess_num)) 

    elif guess_num < random_number: 
     print("Sorry that number is too low.") 
     guess_low = input("Guess a number between {} and 100 .".format(guess_num)) 

    else: 
     print("Sorry, but my number was {}".format(random_number)) 
     print("You are out of tries. Better luck next time.")

import random 
random_number = random.randint(1,100) 
tries = 0 
guess = input("Guess a random number between 1 and 100.")  
while tries < 800: 
    tries += 1 
    try: 
    guess_num = int(guess) 
    except: 
    print("That's not a whole number!") 
    break 

    if not guess_num > 0 or not guess_num < 101: 
    print("That number is not between 1 and 100.") 
    break 

    elif guess_num == random_number: 
    print("Congratulations! You are correct!") 
    print("It took you {} tries.".format(tries)) 
    break 

    elif guess_num > random_number: 
     print("Sorry that number is too high.") 
     guess = input("Guess a number between 0 and {} .".format(guess_num)) 

    elif guess_num < random_number: 
     print("Sorry that number is too low.") 
     guess = input("Guess a number between {} and 100 .".format(guess_num)) 

else: 
    print("Sorry, but my number was {}".format(random_number)) 
    print("You are out of tries. Better luck next time.")

對於這種情況下，貴僅環重複一次？

循環將打破（因爲你有下的第15行break語句「如​​果不是guess_num> 0或不guess_num < 101」），如果輸入的猜測是小於0或大於100

如果用戶在1到100之間輸入了錯誤的猜測，那麼代碼會循環，因此用戶會被要求輸入另一個數字。

儘管它循環，循環沒有更新範圍。 您可以做的是將range_min和range_max設置爲變量，並根據猜測值是否過低或過高來更改這些變量。 請看下面的代碼：

import random 
random_number = random.randint(1,100) 
tries = 0 
range_min = 0 
range_max = 100 
while tries < 800: 
    guess = input("Guess a random number between " + str(range_min +1) + " and " + str(range_max))  
    tries += 1 
    try: 
    guess_num = int(guess) 
    except: 
    print("That's not a whole number!") 
    break 

    if not guess_num > range_min or not guess_num < (range_max+1): 
    print("That number is not between str(range_min +1) + " and " +  str(range_max)") 
    break 

    elif guess_num == random_number: 
    print("Congratulations! You are correct!") 
    print("It took you {} tries.".format(tries)) 
    break 

    elif guess_num > random_number: 
     print("Sorry that number is too high.") 
     guess_high = input("Guess a number between 0 and {} .".format(guess_num)) 
range_max = guess_num 

    elif guess_num < random_number: 
     print("Sorry that number is too low.") 
     guess_low = input("Guess a number between {} and 100 .".format(guess_num)) 
range_min = guess_num 

    else: 
     print("Sorry, but my number was {}".format(random_number)) 
      print("You are out of tries. Better luck next time.")

1. 不要使用break，因爲他們終止while循環。請參閱python語言參考。

2. 您應該只詢問一次guess_num。當猜測過高或過低時（BTW變量名稱guess不正確），刪除兩個input。

3. 最後一個條件（出的嘗試）應該是while循環外，因爲當嘗試的次數超過800

4. 提示它就會被執行。用戶可以用二進制搜索來玩這個遊戲（從50開始，然後根據更高/更低等級猜測25或75）。你應該允許8次嘗試（不是800次）。

這裏是如何更新範圍：

import random 
random_number = random.randint(1,100) 
tries = 0 
low = 0 
high = 100 
while tries < 800: 
    if(tries == 0): 
    guess = input("Guess a random number between {} and {}.".format(low, high))  
    tries += 1 
    try: 
    guess_num = int(guess) 
    except: 
    print("That's not a whole number!") 
    break  

    if guess_num < low or guess_num > high: 
    print("That number is not between {} and {}.".format(low, high)) 
    break  

    elif guess_num == random_number: 
    print("Congratulations! You are correct!") 
    print("It took you {} tries.".format(tries)) 
    break  

    elif guess_num > random_number: 
     print("Sorry that number is too high.") 
     high = guess_num 
     guess = input("Guess a number between {} and {} .".format(low, high))  

    elif guess_num < random_number: 
     print("Sorry that number is too low.") 
     low = guess_num 
     guess = input("Guess a number between {} and {} .".format(low, high))  

    else: 
     print("Sorry, but my number was {}".format(random_number)) 
     print("You are out of tries. Better luck next time.")

這裏是我會怎麼做。不知道它的工作原理，但做法是：

import random 

random_number = random.randint(1,100) 
max_tries = 100 
tries = 0 
left = 0 
right = 100 
found = False 


def get_number(): 
    try: 
     guess = int(input("Guss a random number between {} and {}".format(left, right)))    
     if guess > right or guess < left: 
      print("That number is not between {} and {}".format(left, right)) 
     return guess 
    except: 
     print("That's not a whole number!") 
     get_number() 

def update_range(guess): 
    if guess >= left: 
     left = guess 
    else: 
     right = guess   

while tries <= max_tries and not found: 
    guess = get_number() 
    tries=+1 
    if guess == random_number: 
     print("Congratulations! You are correct!") 
     print("It took you {} tries.".format(tries)) 
     found = True 
    else: 
     update_range(guess) 

    if not found: 
     print("Sorry, but my number was {}".format(random_number)) 
     print("You are out of tries. Better luck next time.") 

正如你可以看到我使用輔助功能以減少的if/else結構的數量。

另外更新範圍是必要的。並感謝參數化的字符串我可以告訴用戶什麼是範圍。

我也設置一個標誌知道用戶是否發現在遊戲
