Something like this, completely untested.

with open(prfile,mode="rt",encoding='utf-8') as pfile:
     lineIter = iter(pfile)
     for _ in range(5):
         next(lineIter)
     for line in lineIter:
          allVals = line.strip().split("\t")
          print(allVals)

I'd also recommend that you use the csv module 
https://docs.python.org/3/library/csv.html which can also cope with tsv 
files, it's far more reliable than relying on a simple call to split().
