python - python regex sub％H:％M:％S到％M:％s或01:％M:％s

我想从转换字符串（字幕）：

585
00:59:59,237 --> 01:00:01,105
- It's all right. - He saw us!

586
01:00:01,139 --> 01:00:03,408
I heard you the first time.

进入


  59:59-没关系。 -他看见了我们！
  
  01:00:01我第一次听到你的声音。


*我想要的是：如果时间在一个小时内，则修剪掉“ 00：”前缀，而如果时间大于1小时则保留它*

我的正则表达式是：

pat = re.compile(r"""
    #\s*                    # Skip leading whitespace
    \d+\s                   # remoe lines contain only numbers
    ((?:(?:00)|(?P<hour>01)):(?P<time>\d{2}:\d{2})[,0-9->]+.*)[\r\n]+(?P<content>.*)[\r\n]+
    """,
    re.VERBOSE)
data = pat.sub(r"\g<hour>\g<time> \g<content>", data)

仅在不使用'\g<hour>'时才有效。
谁能帮我？

最佳答案

我认为，这就是您要寻找的：

import re

s = """
585
00:59:59,237 --> 01:00:01,105
- It's all right. - He saw us!

586
01:00:01,139 --> 01:00:03,408
I heard you the first time.
"""

for line in re.findall(r'(\d+:)(\d+:\d+)(?:.*\n)(.*)', s):
    if line[0] == '00:':
        print ' '.join(line[1:])
    else:
        print ' '.join([''.join(line[0:2]), line[2]])

输出：

# 59:59 - It's all right. - He saw us!
# 01:00:01 I heard you the first time.
