hi all,
thanks for all your advice, i really learn a lot.
finally i modified the code to be working as:
fname = "sampledata.txt"
pattern = "-1"
failure = False
for search in open(fname):
if pattern in search:
#print search
#print failure
failure=True
print 'Lane', search.split()[2], 'Fail'
if not failure:
print "All Lanes Pass"
thanks
