Python: Match string with multiple patterns

Question

I have below string in variables

'''
                                 Messages  Retrans   Timeout   Unexpected-Msg
           INVITE ---------->         30        0         0
              100 <----------         30        0         0         0
              180 <----------         12        0         0         18
              200 <----------         12        0         0         0

              ACK ---------->         12        0
             INFO ---------->         12        0         0
              200 <----------         12        0         0         0
       Pause [         10.0s]         12                            0
              BYE ---------->         12        0
              200 <----------         12        0         0         0

'''

How can i get below regex match output with one pattern or min pattern.

[('INVITE', '---------->', '30', '0', '0'), ('100', '<---------- ', '30', '0', '0', '0'), ('180', '<---------- ', '12', '0', '0', '18'), ('200', '<---------- ', '12', '0', '0', '0'), ('ACK', '---------->', '12', '0'), ('INFO', '---------->', '12', '0', '0'), ('200', '<---------- ', '12', '0', '0', '0'), ('BYE', '---------->', '12', '0'), ('200', '<---------- ', '12', '0', '0', '0')].

I have used below script t get the output. +++++++++++++++++++++++++++++++++++++

So first of all, you haven't format your question well. I try to format it for you but you need more text to explain.

basically from my understanding, the question is having a string a :

a = '''
  2 open sockets

                                 Messages  Retrans   Timeout   Unexpected-Msg
           INVITE ---------->         30        0         0
              100 <----------         30        0         0         0
              180 <----------         12        0         0         18
              200 <----------         12        0         0         0

              ACK ---------->         12        0
             INFO ---------->         12        0         0
              200 <----------         12        0         0         0
       Pause [         10.0s]         12                            0
              BYE ---------->         12        0
              200 <----------         12        0         0         0

'''

you wanted to get all the result like this: ('INVITE', '---------->', '30', '0', '0'),

I used the following regex line to achieve:

import re

a = '''
  2 open sockets

                                 Messages  Retrans   Timeout   Unexpected-Msg
           INVITE ---------->         30        0         0
              100 <----------         30        0         0         0
              180 <----------         12        0         0         18
              200 <----------         12        0         0         0

              ACK ---------->         12        0
             INFO ---------->         12        0         0
              200 <----------         12        0         0         0
       Pause [         10.0s]         12                            0
              BYE ---------->         12        0
              200 <----------         12        0         0         0

'''
pattern = re.compile(r'(?P<type>\d+|\w+)\s*(?P<dir>\<?\-+\>?)\s+(?P<messages>\d*)[\n\r\s]*(?P<retrans>\d*)[\n\r\s]*(?P<timeout>\d*)[\n\r\s]*(?P<unexpected_msg>\d*)\n',flags=re.MULTILINE)
result = pattern.finditer(a)
result_list = [m.groupdict() for m in result]

output for result:

...:for i in result_list:
    print(i)

...:
{'type': 'INVITE', 'dir': '---------->', 'messages': '30', 'retrans': '0', 'timeout': '0', 'unexpected_msg': ''}
{'type': '100', 'dir': '<----------', 'messages': '30', 'retrans': '0', 'timeout': '0', 'unexpected_msg': '0'}
{'type': '180', 'dir': '<----------', 'messages': '12', 'retrans': '0', 'timeout': '0', 'unexpected_msg': '18'}
{'type': '200', 'dir': '<----------', 'messages': '12', 'retrans': '0', 'timeout': '0', 'unexpected_msg': '0'}
{'type': 'ACK', 'dir': '---------->', 'messages': '12', 'retrans': '0', 'timeout': '', 'unexpected_msg': ''}
{'type': 'INFO', 'dir': '---------->', 'messages': '12', 'retrans': '0', 'timeout': '0', 'unexpected_msg': ''}
{'type': '200', 'dir': '<----------', 'messages': '12', 'retrans': '0', 'timeout': '0', 'unexpected_msg': '0'}
{'type': 'BYE', 'dir': '---------->', 'messages': '12', 'retrans': '0', 'timeout': '', 'unexpected_msg': ''}
{'type': '200', 'dir': '<----------', 'messages': '12', 'retrans': '0', 'timeout': '0', 'unexpected_msg': '0'}

then you can iterate the result_list .

Instead of using list of tuple as you mentioned in the question, because i think you may wants to know what value is missing. ('ACK', '---------->', '12', '0') like this may not tell you which 2 value is missing because i saw at line pause there is only message value and unexpected-msg value. Pause [ 10.0s] 12 0

hope this is what you are looking for and please add more description to the question so that you can format your code nicely.
