Two different ways to translate mRNA to Protein

from Bio.Seq import Seq
from Bio.Alphabet import IUPAC


def translate(mRNA):
    '''(str) -> str

    input is mRNA string and it returns a the corresponding protein string.

    >>>translate('AUGGCCAUGGCGCCCAGAACUGAGAUCAAUAGUACCCGUAUUAACGGGUGA')
    MAMPRTEINSTRING

    Precondition: mRNA has to be Uppercase and include only GAUC
   
    '''
    #IUPAC.unambiguous_rna includes only Uppercase and GAUC
    messenger_rna = Seq(mRNA, IUPAC.unambiguous_rna)
    #translate using a dict already stored in the method
    protein = messenger_rna.translate()

    print protein

def translate_2(mRNA):
    '''(str) -> str

    input is mRNA string and it returns a the corresponding protein string.

    >>>translate('AUGGCCAUGGCGCCCAGAACUGAGAUCAAUAGUACCCGUAUUAACGGGUGA')
    MAMPRTEINSTRING

    #this string will be used to make a dict
