Question

import random  

print("Welcome to the Number Guessing Game!\n")  
print("We are going to pick a number and have the computer guess it.")  
answer = int(input("Pick a number between 1 and 100:\n"))  
guess = random.randint(1, 100)  
guesses = 1  
while guess != answer:  
    if guess > answer:  
        guess = random.randint(1, guess)  
        print(guess)  
    elif guess < answer:  
        guess = random.randint(guess, 100)  
        print(guess)    
    guesses += 1  
print("\nWhoopy, I guessed correct.\n")  
print("It took me %s guesses to guess %s." % (guesses, answer))

这是我到目前为止所拥有的。我不确定如何构建 if 和 elif 以确保没有猜测

Answer 1

我怀疑你想要两个额外的变量来限制你guess的界限。试试这个：

low = 1
high = 100
guess = random.randint(low, high)  
guesses = 1  
while guess != answer:
    if guess > answer:
        high = guess - 1
        print(guess)  
    elif guess < answer:  
        low = guess + 1
        print(guess) 
    guess = random.randint(low, high)     
    guesses += 1  
print("\nWhoopy, I guessed correct.\n")  
print("It took me %s guesses to guess %s." % (guesses, answer))

如果你没有随机猜测，你实际上会做得更好，而是总是选择low和high之间的中点。这是binary search algorithm。

Answer 2

您希望添加min和max变量以跟踪当前范围。

min = 1; max = 100
guess = random.randint(min, max)  
guesses = 1  
while guess != answer:  
    if guess > answer:  
        min = guess+1  
        print(guess) 
    elif guess < answer:
        max = guess-1
        print(guess)
    guess = random.randint(min, max)    
    guesses += 1

Answer 3

我不知道如何形成if和elif以确保没有猜测

您应首先将名称绑定到1，100值。然后你可以有意义地分配给他们。

while guess != answer:
    if guess > answer:
        range_max = guess - 1
        guess = random.randint(range_min, guess)
        print(guess)
    elif guess < answer:
        range_min = guess + 1
        guess = random.randint(guess, range_max)
        print(guess)
    guesses += 1

Answer 4

您可以立即生成所有猜测，然后修剪大于或小于猜测的猜测列表：

import random  

print("Welcome to the Number Guessing Game!\n")  
print("We are going to pick a number and have the computer guess it.")  
answer = int(input("Pick a number between 1 and 100:\n"))  
guesses=random.sample(range(1, 101), 100)
count = 1  
guess=guesses.pop()
while guess != answer:  
    if guess > answer:  
        guesses=[e for e in guesses if e<guess] 
        print(guess)  
    elif guess < answer:  
        guesses=[e for e in guesses if e>guess] 
        print(guess)    
    guess=guesses.pop()    
    count += 1  
print("\nWhoopy, I guessed correct.\n")  
print("It took me %s guesses to guess %s." % (count, answer))

在while循环期间更新范围，因此无需猜测
