to print lines after a pattern match using python

Question

i was trying to match a pattern which is Slack (MET)

^[^:\n](^Slack\n(MET)$)\s\n^[(d)]* , when i use this pat am getting the lines data arrival time and also slack(MET) is getting matched with next line

i want to get the data after start point through looping,i tried to match pattern using regex and it got matched, but when i try to take inside loop am not getting any o/p. i tried this code

import re

file = open(input("Input-file name : ") , "r")

fi = file.readlines()

pat=(r'^[^\n(E|P):]:\s[EXINTF_DATA\d]\d')

c = 0

for line in fi:

if re.match(pat,line):

    print(line) 

while True:

c+=1

print(line)

break

have attached code & o/p for the same

                       4.29[![text file image as well is attached][2]][2]

my desired o/p from the file is: to search for the pattern ^[^\n(E|P):]:\s[EXINTF_DATA\d]\d this is the pattern for Startpoint:EXINTF_DATA, i want to print the lines after this till Slack (MET) is found and have to break the loop & has to start from the beginning where the same 'Startpoint:' pattern is found and continue the same for the text file everytime. I tried this using Wile and for loop,but not getting any o/p. Am new to Python, so please someone help me pls. pls ask if you don't understand anything. Also, have tried with sources i have with SO and also pynative. pls help me how to go about it.
