New submission from Garrett Cooper:
I was a bit surprised when I ran into this issue when porting some nose tests
from Windows to Linux:
#!/usr/bin/env python
with open('/etc/services') as fd:
lines = fd.readlines()
lines.append('')
SERVICES = [line.split()[0] for line in lines
Peter Otten added the comment:
I believe you are misinterpreting what you are seeing. Empty lines read from a
file do not produce an empty string, you get \n instead which is true in a
boolean context.
Try
[line.split()[0] for line in lines if line.strip() and not line.startswith(#)]
or add
