Python：如何从字符串中生成单词列表并根据其索引将其保存在文本文件中？

Question

with open('filename.txt', "r") as word_list:
    words = word_list.read().split('')


with open("file.txt", "w") as output:
    output.write(str(words))

But the output is not in order (I want one word per line) as I want them to be. My apology: I am a very beginner in python. Thanks in advance if anyone can figure out how I can sort words using python according to the index from the list.

Something like this might work:

with open('filename.txt', "r") as word_list:
    words = word_list.read().split(' ')

with open("file.txt", "w") as output:
    for index, word in enumerate(words):
        output.write(f'{index}. {word}\n')

The code uses the built-in enumerate function to loop through the list of words with an index (0-based). It also uses string interpolation (so called f-strings ) to build the correct output string.
