Let me modify this example:
a = [['jimmy', '25', 'pancakes'], ['tom', '23', 'brownies'], ['harry',
'21', 'cookies']]
for i in a:
*b = i[0]*
if (i[1] == '25' or i[1] == '26'):
print *b*
else:
print 'Not found'
This will output:
*jimmy*
*Not found*
*Not found*
*
*
How do I print positive matches (*jimmy*) only and not (*Not found*). I
also want *Not found *to print only *once *if there are no positive matches.
