"lista" has to be a list of strings. sorted is your friend here. Sorting Mini-HOW TO

def memory_mult(text):
    memory = {'KB':1024, 'MB':1024**2, 'GB':1024**3}
    num = text[:-2]
    mult = text[-2:]
    return int(num)*memory[mult]

sorted(lista, key=memory_mult)

using `float(num)` instead of `int(num)` may be robust. – era_misa Mar 25 '18 at 14:12
