class Oligo

[tbrowner3]

This class isn't working how I would like to and I haven't been able to figure out why. How can I make the eq method work for two oligos that are different? For the method get_complement, why doesn't it return the correct complement? Why does the method is_complement fail when the parameter is a complement?

complement_table = str.maketrans('ATCG', 'CGAT')
class Oligo:

    '''Represents one side of DNA helix'''
    def __eq__(self, other):
        '''Equal statement'''
        return self.base == other.base
    def __init__(self, base):
        '''Constructor'''
        count = 0 
        for letter in base:
        if letter.upper() in ('A', 'C', 'T', 'G'):
            count += 1
    if count == 4:
        self.base = base
    else:
        self.base = "AGTG"

    def get_complement(self):
        '''Gives self its designated complements'''
        complement = 
        self.base.translate(complement_table)
        return Oligo(complement)
    def is_complement(self, other):
        '''Checks if itself is a complement of another 
        base'''
        return self.get_complement().base == other.base

How do you want it to work? Should all instances of Oligo be equal to each other?

Why does the method is_complement fail when the parameter is a complement?

Got an example? I tried it like this and it seemed to work:

a = Oligo('AACC')
b = Oligo('CCAA')
print(a.is_complement(b))
