learning Python from Perl here. Want to do things as Pythonicly as

I am reading a TSV, but need to skip the first 5 lines. The following
works, but wonder if there's a more pythonc way to do things. Thanks
ctr = 0
with open(prfile,mode="rt",encoding='utf-8') as pfile:
for line in pfile:
ctr += 1
if ctr < 5:
continue
allVals = line.strip().split("\t")
print(allVals)
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().
