I know this is a python list but if you really want to get the job
done quickly this is one method without writing python code:

$ cat /tmp/y
AAAAAGACTCGAGTGCGCGGA   0
AAAAAGATAAGCTAATTAAGCTACTGG     0
AAAAAGATAAGCTAATTAAGCTACTGGGTT   1
AAAAAGGGGGCTCACAGGGGAGGGGTAT     1
AAAAAGGTCGCCTGACGGCTGC  0
$ grep -v 0 /tmp/y > tmp/z
$ cat /tmp/z
AAAAAGATAAGCTAATTAAGCTACTGGGTT   1
AAAAAGGGGGCTCACAGGGGAGGGGTAT     1

Regards
Johann
