You're gong crazy: >>> ips = ['255.255.255.255', '128.173.120.79', '198.82.247.98', ... '127.0.0.1', '255.0.0.0', '255', '128.173.255.34'] >>> for ip in ips: ... if '255' in ip: print ip ... 255.255.255.255 255.0.0.0 255 128.173.255.34 The problem is that you're operating in-place on an array while it's being iterated over. Since the iterator is only created once, you're can't change the array while you're iterating over it. Instead, try a list comprehension: >>> ips = [ip for ip in ips if '255' not in ip] >>> ips ['128.173.120.79', '198.82.247.98', '127.0.0.1'] Peace Bill Mill bill.mill at gmail.com -- http://mail.python.org/mailman/listinfo/python-list
