Calculate statistics

Statistics

Compute the length, base counts, and GC content of the sequence.

def statistics(seq):
    return {
        "length": len(seq),
        "A": seq.count("A"),
        "T": seq.count("T"),
        "G": seq.count("G"),
        "C": seq.count("C"),
        "gc": (seq.count("G") + seq.count("C")) / len(seq) * 100
    }

print(statistics("ATGCGCAT"))
