字幕文件读取
# 读取字幕文件
def read_srt(path):
content = ""
with open(path,'r', encoding='UTF-8') as f:
content = f.read()
return content

# 字幕拆分
def get_sequences(content):
sequences = content.split('\n\n')
sequences = [sequence.split('\n') for sequence in sequences]
# 去除每一句空值
sequences = [list(filter(None, sequence)) for sequence in sequences]
# 去除整体空值
return list(filter(None, sequences))

srt_path='./audio/333.zh-cn.srt'
content = read_srt(srt_path)
sequences = get_sequences(content)
print(sequences)

结果：
[[‘1’, ‘00:00:00,000 --> 00:00:00,790’, ‘活着’],
[‘2’, ‘00:00:01,730 --> 00:00:02,860’, ‘所为何事先生’],
[‘3’, ‘00:00:03,140 --> 00:00:05,010’, ‘我们在京城有一箱22任务’],
[‘4’, ‘00:00:05,230 --> 00:00:06,440’, ‘把这些人找过来’],
[‘5’, ‘00:00:07,010 --> 00:00:08,230’, ‘你就要辛苦一下了’], [‘6’, ‘00:00:09,290 --> 00:00:10,900’, ‘这一次我们要一起合作’], [‘7’, ‘00:00:11,020 --> 00:00:12,040’, ‘有目标是谁’],。。。

转换时间
strTime= '00:00:58,990'

def strFloatTime(tempStr):
xx = tempStr.split(':')
hour = int(xx[0])
minute = int(xx[1])
second = int(xx[2].split(',')[0])
minsecond = int(xx[2].split(',')[1])
allTime = hour * 60 * 60 + minute * 60 + second + minsecond / 1000
return allTime
print(strFloatTime(strTime))
