正在更改 python 中文本文件的格式

Question

我正在尝试遍历如下所示的文本文件：

Funny Dogs | funny_dogs_video_id | #dog , #animal
Amazing Cats | amazing_cats_video_id | #cat , #animal
Another Cat Video | another_cat_video_id |  #cat , #animal
Life at Google | life_at_google_video_id |  #google , #career
Video about nothing | nothing_video_id |

我需要能够将文件打印成如下所示：

Funny Dogs (funny_dogs_video_id)  [#dog , #animal]
Amazing Cats ( amazing_cats_video_id )  [#cat , #animal]
Another Cat Video ( another_cat_video_id ) [ #cat , #animal]
Life at Google (life_at_google_video_id)  [#google , #career]
Video about nothing (nothing_video_id) []

我需要以“title(video_id)[tag]”格式列出所有可用视频

到目前为止我的代码：

def show_all_videos(self):
    print("Here's a list of all available videos: ")
    with open('/Users/Name/code-sample/python/src/videos.txt')as f:
        lines = f.readlines()
        lines.sort()
        available_videos = ""
        for line in lines:
            available_videos += line
        print(available_videos)

但是，我的代码以与文本文件已经存在的格式相同的格式输出我的文件。有什么建议可以将此代码的格式更改为我想要的格式吗？

也许和

一样简单

with open("videos.txt") as fh_src, open(destination, "w") as fh_dest:
    for line in fh_src:
        title, video_id, tags = line.split("|")
        # rewrite line here, such as calling .strip() on the fields
        fh_dest.write(f"{title} ({video_id}) [{tags}]\n")

Answer 2

尝试：

with open("videos.txt") as f:
    lines = [l.strip() for l in f.readlines()]

available_videos = ""
for line in lines:
    title, video, tags = [x.strip() for x in line.split("|")]
    available_videos += f"{title} ({video}) [{tags}]\n"

>>> print(available_videos)
Funny Dogs (funny_dogs_video_id) [#dog , #animal]
Amazing Cats (amazing_cats_video_id) [#cat , #animal]
Another Cat Video (another_cat_video_id) [#cat , #animal]
Life at Google (life_at_google_video_id) [#google , #career]
Video about nothing (nothing_video_id) []

Answer 3

在 '|' 处拆分您的行并根据需要打印数据。

for line in lines:
    title, video_id, tag = line.split('|')
    print(f'{title} ({video_id}) [{tag}]')
