No need for pass in build_frequency_table

[jmcrey]

def build_frecuency_table(corpus):
    frequency_table = {} #initialise the dictionary
    for element in corpus:
        if element in frequency_table.keys(): #if the element is already in the dictionary add 1 to the value of the key 
            frequency_table[element] += 1
            pass #when we increase the value of the counter of the key, we pass to the next word
        else: #if we don't have the element in the dictionary we create a new one and initialise the counter
            frequency_table[element] = 1
    return frequency_table

Really nice job with this function! I just wanted to point out that we don't need pass in this function. Usually, pass is used as a placeholder to avoid implementing a function. In this case, we can just remove it from our function -- the logic of the if - else statement will ensure that an element is not unnecessarily reset to 1.

In any case, this is just a suggestion; have pass in this function does no harm!
