unless statement in Python

Question

Is there an equivalent to the unless statement in Python? I do not want to append a line to a label if it has p4port in it:

for lin         


        

Answer 1

What about 'not in'?:

if 'p4port' not in line:
    labels.append(line)

Also i guess that you code can be modified then to:

if '@' in line and line == l and 'p4port' not in line:
    lineMatch = True
    labels.append(line.strip('\n').split('@')[1] + '
\n')
