問題是只輸入了一個單詞并且對其調(diào)用了排序方法。

讓我們獲取多個單詞，將它們附加到列表中并對它們進行排序：

input_words = []

# Get input words

word = input('Please enter word\n')

# As long as word is not "stop"

while word != 'stop':

    # Get new input word

    input_words.append(word)

    # Append to list of words

    word = input('Please enter word\n')

# Sort words

input_words.sort()

# Print sorted list of words

print(input_words)

# Write to file

with open('your_file.txt', 'w') as f:

    for item in input_words:

        f.write("%s\n" % item)
