问题：While 循环不会正确地重新运行程序

Question

user_input = input('Welcome to the Scribble Scorer; Enter Word:')

i = {'e': 1, 't': 1.5, 'a': 2, 'i': 2, 'n': 2, 's': 2, 'h': 2.5, 'r': 2.5, 'd': 2.5, 'l': 3, 'u': 3, 'c': 3.5, 'm': 3.5, 'f': 4, 'w': 4.5, 'y': 4.5, 'p': 5, 'g': 5, 'b': 5.5, 'v': 5.5, 'k': 5.5, 'q': 5.5, 'j': 6, 'x': 6, 'z':6}

totalValue = 0
    for char in user_input: # For every character in our string.
        if char in i: # If this character has a defined weight value.
            totalValue += i[char] # Add it to our total.

print('Word:', user_input, 'Score:', totalValue)


while user_input != 'nothing':
    user_input = input('Welcome to the Scribble Scorer; Enter Word:')

    if user_input != 'nothing':
    
        print('Word:', user_input, 'Score:', totalValue)

结果：

Welcome to the Scribble Scorer; Enter Word: fazli
Word: fazli Score: 17
Welcome to the Scribble Scorer; Enter Word: mia
Word: mia Score: 17
Welcome to the Scribble Scorer; Enter Word:

目前，我的程序将根据用户输入的内容打印分数。第一次输入后，'fazli'得分为17。

我的 while 循环应该保持运行，直到用户什么都不输入。

我认为问题出在我的 while 循环上。它不会产生新的分数，它只会复制第一个分数。

如何在不复制第一个输入的单词分数的情况下保持运行我的 while 循环？

Answer 1

因为您没有在 while 循环中更新分数。您必须在每次迭代时重新计算它。我给你改了。

i = {'e': 1, 't': 1.5, 'a': 2, 'i': 2, 'n': 2, 's': 2, 'h': 2.5, 'r': 2.5, 'd': 2.5, 'l': 3, 'u': 3, 'c': 3.5, 'm': 3.5, 'f': 4, 'w': 4.5, 'y': 4.5, 'p': 5, 'g': 5, 'b': 5.5, 'v': 5.5, 'k': 5.5, 'q': 5.5, 'j': 6, 'x': 6, 'z':6}
user_input = input('Welcome to the Scribble Scorer; Enter Word:')
while user_input != 'nothing':
    totalValue = 0
    for char in user_input: # For every character in our string.
        if char in i: # If this character has a defined weight value.
            totalValue += i[char] # Add it to our total.
    print('Word:', user_input, 'Score:', totalValue)
    user_input = input('Welcome to the Scribble Scorer; Enter Word:')

Answer 2

i = {'e': 1, 't': 1.5, 'a': 2, 'i': 2, 'n': 2, 's': 2, 'h': 2.5, 'r': 2.5, 'd': 2.5, 'l': 3, 'u': 3, 'c': 3.5, 'm': 3.5, 'f': 4, 'w': 4.5, 'y': 4.5, 'p': 5, 'g': 5, 'b': 5.5, 'v': 5.5, 'k': 5.5, 'q': 5.5, 'j': 6, 'x': 6, 'z':6}
#take user input
user_input = input('Welcome to the Scribble Scorer; Enter Word:')
#check if its not 'nothing'
while user_input != 'nothing':
    totalValue = 0
    #compute the score
    for char in user_input: 
        if char in i: 
            totalValue += i[char] 
    print('Word:', user_input, 'Score:', totalValue)
    #get user input again for next iteration
    user_input = input('Welcome to the Scribble Scorer; Enter Word:')

Answer 3

也可以将其构建为如下函数

i = {'e': 1, 't': 1.5, 'a': 2, 'i': 2, 'n': 2, 's': 2, 'h': 2.5, 'r': 2.5, 'd': 2.5, 'l': 3, 'u': 3, 'c': 3.5,
     'm': 3.5, 'f': 4, 'w': 4.5, 'y': 4.5, 'p': 5, 'g': 5, 'b': 5.5, 'v': 5.5, 'k': 5.5, 'q': 5.5, 'j': 6, 'x': 6, 'z': 6}


def calculate_score(word: str):
    totalValue = 0
    for char in word:  # For every character in our string.
        if char in i:  # If this character has a defined weight value.
            totalValue += i[char]  # Add it to our total.
    return totalValue


user_input = ''
while user_input != 'nothing':
    user_input = input('Welcome to the Scribble Scorer; Enter Word:')

    if user_input != 'nothing':
        totalValue = calculate_score(user_input)
        print('Word:', user_input, 'Score:', totalValue)
