Answer 1

这可以通过阅读原始文件的内容并将添加的单词附加到每一行来实现

示例：

# changed the name to list_obj to prevent overriding builtin 'list'
list_obj = ['something','foo','foooo','bar','bur','baar']
path_to_file = "a path name.txt"

# r+ to read and write to/from the file
with open(path_to_file, "r+") as fileobj:
    # read all lines and only include lines that have something written
    lines = [x for x in fileobj.readlines() if x.strip()]
    # after reading reset the file position
    fileobj.seek(0)
    # iterate over the lines and words to add
    for line, word in zip(lines, list_obj):
        # create each new line with the added words
        new_line = "%s %s\n\n" % (line.rstrip(), word)
        # write the lines to the file
        fileobj.write(new_line)
