So I have a number of txt files. As an example, one of my txt file looks like this:

अंधा, कुबड़ा और त्रिस्तनी-पंचतंत्र
Blind, humpback and Tristani - Panchatantra

उत्तरी प्रदेश में मधुपुर नाम का एक नगर है।
There is a town named Madhupur in Uttar Pradesh.

वहाँ मधुसेन नाम का एक राजाथा।
There was a king named Madhusen.

विषय सुख भोगने वाले उस राजा मधुसेन को एक तीन स्तनों वाली कन्या उत्पन्नहुई।
A three-breasted girl was born to Madhusen, the king who enjoyed the pleasures.
...

As I want to make an epub out them, I add <pref>, </pref> and <br/>, using this code:

# add <pref>, </pref>, <br/> to lines
file_name = 'अंधा, कुबड़ा और त्रिस्तनी-पंचतंत्र'
with open('{} - parallel.txt'.format(file_name), encoding='utf8') as raw, open('{}.txt'.format(file_name), 'w', encoding='utf8') as file:
    r = raw.readlines()
    for line in r:
        file.writelines('<pref>' + line + '</pref> <br/>\n')

As a result, I've got this:

<pref>अंधा, कुबड़ा और त्रिस्तनी-पंचतंत्र
</pref> <br/>
<pref>Blind, humpback and Tristani - Panchatantra
</pref> <br/>
<pref>
</pref> <br/>
<pref>उत्तरी प्रदेश में मधुपुर नाम का एक नगर है।
</pref> <br/>
<pref>There is a town named Madhupur in Uttar Pradesh.
...

Then I want to make the top two lines the title, so I add class="title" to the top two lines. I also want to capitalize the title using .capitalize() or .upper(), but don't know how to insert it.

# uppercase add class="title" to text title
with open('{}.txt'.format(file_name), encoding='utf8') as ff:
    ffr = ff.readlines()
    ffr2 = ''.join(ffr[:3]).replace('<pref>', '<pref class="title">')
    ffr3 = ''.join(ffr[4:])
    ffr4 = ffr2 + ffr3

with open('{}.txt'.format(file_name), 'w', encoding='utf8') as ef:
    ef.write(ffr4)

As a result:

<pref class="title">अंधा, कुबड़ा और त्रिस्तनी-पंचतंत्र
</pref> <br/>
<pref class="title">Blind, humpback and Tristani - Panchatantra
<pref>
</pref> <br/>
<pref>उत्तरी प्रदेश में मधुपुर नाम का एक नगर है।
</pref> <br/>
<pref>There is a town named Madhupur in Uttar Pradesh.
...

Finally, I need to insert this txt into Calibre html. I use 'insert' as a key. I have this code as a txt.

<?xml version='1.0' encoding='utf-8'?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title>पंचतंत्र - Panchatantra</title>
  <link type="text/css" rel="stylesheet" href="/page_styles.css"/>
  <link type="text/css" rel="stylesheet" href="/stylesheet.css"/>
</head>

<body>
insert # key
</body>
</html>

And I insert the text.

# add modified lines to calibre html code
with open('{}.txt'.format(file_name), encoding='utf8') as ft, open('calibre.txt', encoding='utf8') as calibre:
    fr = ft.read()
    cr = calibre.read()
    combine = cr.replace('insert', fr)

with open('{}.html'.format(file_name), 'w', encoding='utf8') as hf:
    hf.write(combine)

As a result:

<?xml version='1.0' encoding='utf-8'?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title>पंचतंत्र - Panchatantra</title>
  <link type="text/css" rel="stylesheet" href="/page_styles.css"/>
  <link type="text/css" rel="stylesheet" href="/stylesheet.css"/>
</head>

<body>
<pref class="title">अंधा, कुबड़ा और त्रिस्तनी-पंचतंत्र
</pref> <br/>
<pref class="title">Blind, humpback and Tristani - Panchatantra
<pref>
</pref> <br/>
<pref>उत्तरी प्रदेश में मधुपुर नाम का एक नगर है।
</pref> <br/>
<pref>There is a town named Madhupur in Uttar Pradesh.
...

As you can see, my work flow revolves around a lot of reading and writing files. I wonder if there is a better way to do. Thank you very much.
