you can read file line line , gather in between markers.

def dispatch(inputfile):     # if separator lines must included, set true     need_separator = true     new = false     rec = []     open(inputfile) f:         line in f:             if "admin server interface begins" in line:                 new = true                 if need_separator:                     rec = [line]                 else:                     rec = []             elif "admin server interface ends" in line:                 if need_separator:                     rec.append(line)                 new = false                 # if not need process further, uncomment following line                 #return ''.join(rec)             elif new:                 rec.append(line)     return ''.join(rec) 

the code above return data if input file not contain ending separator (admin server interface ends). can amend last return condition if want catch such files:

if new:     # handle case there no end separator     print("error in input file: no ending separator")     return '' else:     return ''.join(rec)
