  1. I read file *.srt

Blockquote
st.title(‘H_E_R_H_I’)

uploaded_file = st.file_uploader(“Выберите файл субтитров *.srt”,

                              type=['srt'],
                              label_visibility="visible"
                              )

a = uploaded_file.read()
a

Blockquote

I get the same text:

b'1\n00:03:19,349 --> 00:03:20,599\nHello.\n\n2\n00:03:21,559 --> 00:03:24,228\nMy name\'s Forrest. Forrest Gump.\n\n3\n00:03:29,776 --> 00:03:31,819\nDo you want a chocolate?\n\n4\n00:03:34,405 --> 00:03:37,825\nI could eat about\na million and a half of these.\n\n5\n00:03:38,993 --> 00:03:44,206\nMy mama always said\nlife was like a box of chocolates.\n\n6\n00:03:46,209 -->

Here all, text of sublitles, time subtitles. But when I read this file *.srt with Pysrt library, I get list all sentenses and list all time sentenses’s

Blockquote
patch = ‘./English_level/Forrest_Gump(1994).srt’
sub = pysrt.open(patch, encoding=‘iso-8859-1’)

print(sub[10].text) # Print 10th sentense
print(sub[10].start.to_time()) # Print 10th start time of sentense
print(sub[10].end.to_time()) # Print 10th end time of sentense

Blockquote

I need to read srt file as pysrt object, because in my programm I use same function end processing.
Thanks
(sorry, I bad know English)

Then use pysrt to read it. What is the issue?

This is a very simple working example:

import pysrt
import streamlit as st

st.title('pysrt Test for Streamlit')

uploaded_file = st.file_uploader("Choose a .srt file", type="srt")

if uploaded_file is not None:
    sub = pysrt.open(uploaded_file.name, encoding='utf-8')
    texts = sub.text
    st.write(texts)

Franky1 thank, but it’s not works.

PyCharm gives it:

File "/home/dron/PycharmProjects/pythonProject2/main.py", line 9, in <module>
    sub = pysrt.open(uploaded_file.name(), encoding='iso-8859-1')
TypeError: 'str' object is not callable

uploaded_file.name
not uploaded_file.name()

No, so that doesn’t work

This below should work.

from tempfile import NamedTemporaryFile
import pysrt
import streamlit as st

st.title('pysrt Test for Streamlit')

uploaded_file = st.file_uploader("Choose a .srt file", type="srt")

if uploaded_file is not None:
    with NamedTemporaryFile(suffix='.srt', delete=False) as tempfile:
        st.info(tempfile.name)
        tempfile.write(uploaded_file.getbuffer())
        sub = pysrt.open(tempfile.name, encoding='utf-8')
    texts = sub.text
    st.markdown(texts, unsafe_allow_html=True)

It’s difficult for me, but this code really works !

Franky1 Thank you for your hard work!
