歌词LRC转字幕SRT的Python实现

歌词LRC转字幕SRT的Python实现，以后有空把gui界面也写出来

import os
import reroot = os.path.dirname(os.path.abspath(__file__));
input = os.path.join(root,'1.lrc');                     #输入文件f_input = open(input,'r');
f_output = open(os.path.join(root,'1.srt'),'w');        #输出文件#初始化第一个时间，并去除歌词常见的开头没有用的部分
num = 1; 
while True:    line = f_input.readline();if len(line) >1:#判断第2个字符是否是数字，若不是跳过（不够严谨）if(not(line[1] >='0' and line[1]<='9')):continue;else:re_result = re.search("\[(.*?)\](.*)",line);  hour = '00';minute = re_result.group(1)[0:2];second = re_result.group(1)[3:5];millisecond = re_result.group(1)[6:8];   time1 = hour + ':' + minute + ':'  + second + ',' + millisecond + '0';content1 =  re_result.group(2);break;try:while True:line = f_input.readline();if line:re_result = re.search("\[(.*?)\](.*)",line);minute = re_result.group(1)[0:2];second = re_result.group(1)[3:5];millisecond = re_result.group(1)[6:8];     print(re_result);if re_result:if content1 != '':#处理时间，上一句歌词和下一句歌词之间的时间间隔为10毫秒if int(millisecond) > 0:                            millisecond = str(int(millisecond) - 1);if len(millisecond) == 1:millisecond = '0' + millisecond;else:if int(second) > 0:second = str(int(second) - 1);if(len(second) == 1):second = '0' + second;millisecond = '99';else:if int(minute) > 0:minute = str(int(minute)-1);if len(minute) == 1:minute = '0' + minute;second = '59';millisecond = '99';else:print('第'+ str(num) + '块时间格式错误!');break;#输出歌词time2 = hour + ':' + minute + ':'  + second + ',' + millisecond + '0';result = str(num) + '\n' + time1 + ' --> ' + time2 + '\n' + content1 + '\n';f_output.write(result);f_output.write('\n');num = num + 1;print(result);#将上一句歌词的结束时间赋值给下一句歌词的开头时间minute = re_result.group(1)[0:2];second = re_result.group(1)[3:5];millisecond = re_result.group(1)[6:8];  time = hour + ':' + minute + ':'  + second + ',' + millisecond + '0';time1 = time;   content1 = re_result.group(2);else:break;
finally:f_input.close();f_output.close();
