A program to test your dna2rna function on a single example.
This assumes that the fasta file you input has a DNA example followed
by the equivalent RNA example.

from readfasta import readfasta
from dna2rna import dna2rna

def rnatest():
    # read in the dna and rna from a fasta file
    # we assume there is exactly one sequence in the fasta file
    filename = input("Please enter the fasta filename: ")
    info = readfasta(filename)
    dnaseq = info[0][2]
    correctrnaseq = info[1][2]

    # print the results
    print('The correct RNA sequence is:')
    print(correctrnaseq)

    print('\nYour RNA sequence is:')
    print(dna2rna(dnaseq))

    if correctrnaseq == dna2rna(dnaseq):
        print("Yay.  They are equal.")
    else:
        print("Better luck next time.")
