Parsing srt subtitles

Question

I want to parse srt subtitles:

    1
    00:00:12,815 --> 00:00:14,509
    Chlapi, jak to jde s
    těma pracovníma světlama?.

    2
    00:00:14,815 -->          


        

Answer 1

Here's a snippet I wrote which converts SRT files into dictionaries:

import re
def srt_time_to_seconds(time):
    split_time=time.split(',')
    major, minor = (split_time[0].split(':'), split_time[1])
    return int(major[0])*1440 + int(major[1])*60 + int(major[2]) + float(minor)/1000

def srt_to_dict(srtText):
    subs=[]
    for s in re.sub('\r\n', '\n', srtText).split('\n\n'):
        st = s.split('\n')
        if len(st)>=3:
            split = st[1].split(' --> ')
            subs.append({'start': srt_time_to_seconds(split[0].strip()),
                         'end': srt_time_to_seconds(split[1].strip()),
                         'text': '
'.join(j for j in st[2:len(st)])
                        })
    return subs

Usage:

import srt_to_dict
with open('test.srt', "r") as f:
        srtText = f.read()
        print srt_to_dict(srtText)
