You can certainly get it down pretty small if you turn it into a function
as I did, and use a list comprehension, but I think it is hard to read.
def search(line):
global search_gates
for gate, index in search_gates:
pos = (line.split()[4]).split("_")[1]
if gate in line:
return " i_a/i_b/ROM/%s %s LOC =%s" % (gate, index, pos)
return "Error"
search_gates=[('B6', '[1:0]'), 'B10', '[3:2]'),
'B14', '[5:4]'), 'B17', '[7:6]')]
print '\n'.join([search(line) for line in lines])
