here is a small snippet of multihash code.

def compute_hash(url):
    try:
        response = urllib.request.urlopen(url[1].atLocation)
        filedata = response.read()
    except urllib.error.HTTPError:
        return pd.DataFrame({'multihash': [pd.np.nan]}, index=[url[0]])
    encoded = multihash.encode(filedata, multihash.SHA2_256)
    return pd.DataFrame({'multihash': [''.join(format(x, '02x') for x in encoded)]}, index=[url[0]])
