python - 如何用python以良好的格式编写文件？

Question

我在一个项目中，试图用 python 编写文件，我正在尝试以很好的格式编写文件。我会尝试很多，但我不知道出了什么问题？

我会尝试：

    def generate_file(self, lyrics):
        self.path()
        print('We are writing file ............')
        with open('filename.srt', 'w') as lrc:
            for i in range(len(lyrics)):
                add = ''
                if lyrics[i].isnumeric():
                    add += '\n'
                elif lyrics[i].isalpha():
                    add += '\n\n'
                lrc.write(lyrics[i]+add)
                add += ''
            lrc.close()
            print('We downloaded your file!')

输出：

我怎样才能做到这一点？

我的项目：

from bs4 import BeautifulSoup
import os, requests, platform


class EpicLyricFinderApp:
    def __init__(self):
        self.text = '%20'.join(input('Enter song name and also include singer: ').split(' '))
        self.url = 'https://www.rentanadviser.com/en/subtitles/subtitles4songs.aspx?src='+self.text
        self.user = None


        self.app()
    def app(self):
        req = requests.get(self.url).content
        soup = BeautifulSoup(req, 'html.parser')
        print('Please wait ...................')
        tag = soup.findAll('table')
        link = [('https://www.rentanadviser.com/en/subtitles/'+l.get('href'))+'&type=srt' for l in [a.find('a') for a in tag]]
        blank_name = [''.join((l.get_text()).split(' ')[17:]) for l in [a.find('a') for a in tag]]
        [print('No. {} ==>> {}'.format(name+1,blank_name[name])) for name in range(len(blank_name))]


        # Get input form user to choice lyrics
        print('='*60)
        while True:
            try:
                 self.user = int(input('Which lyrics you wanna download?: '))
            except ValueError:
                continue
            else:
                break


        # Open .srt link
        req1 = requests.get(link[self.user]).content
        soup1 = BeautifulSoup(req1, 'html.parser')
        lyrics = [c.get_text() for c in soup1.findAll('span', attrs={'id':'ctl00_ContentPlaceHolder1_lblSubtitle'})]
        self.generate_file(lyrics)





    @staticmethod
    def path():
        if platform.system()=='Linux':
            linux = '/home/rohit/Desktop/lrc'
            if os.path.exists(linux):
                os.chdir(linux)
            else:
                os.mkdir(linux)
                os.chdir(linux)
        else:
            windows = 'Cd:/Users/ABC/rohit/Desktop/lrc'
            if os.path.exists(windows):
                os.chdir(windows)
            else:
                os.mkdir(windows)
                os.chdir(windows)

    def generate_file(self, lyrics):
        self.path()
        print('We are writing file ............')
        with open('_'.join(self.text.split('%20'))+'.srt', 'w') as lrc:
            for i in range(len(lyrics)):
                add = ''
                if lyrics[i].isnumeric():
                    add += '\n'
                elif lyrics[i].isalpha():
                    add += '\n\n'
                lrc.write(lyrics[i]+add)
                add += ''
            lrc.close()
            print('We downloaded your file!')



if __name__ == '__main__':
    app = EpicLyricFinderApp()
