問題：While回圈無法正確重新運行程式

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)

結果：

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，我的程式將根據用戶輸入的內容列印分數。第一次輸入后，'fazli' 得分為 17。

我的 while 回圈應該一直運行，直到用戶不輸入任何內容。

問題是我相信我的 while 回圈。它不會產生新的分數，它只會復制第一個分數。

如何在不復制第一個輸入的單詞分數的情況下繼續運行我的 while 回圈？

因為你沒有在 while 回圈中更新分數。您必須在每次迭代時重新計算它。我給你改了。

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:')

也可以將其構建為如下功能

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)
