Hello everybody,
I have the following problem:
A have a series of strings, some of them are DNA strings (so they
contain only ACGT), other not.
How can I filter out not DNA strings?
Maybe this can be properly done quickly with regular expression
in python, without using biopython.
Does anyone know how to do that with regular expression ?
Thank you very much,
Enrico.
