basic def / if question

[tryingtolearnpython]

Hi everyone,

I'm very new to Python so my questions may be very basic for most of you.

I am not sure I understand the below function. The part I am having trouble understanding is:

reactions = nacho_table.column('Reactions')
    number_wow_reactions = np.count_nonzero(reactions == 'Wow!')
    number_meh_reactions = np.count_nonzero(reactions == 'Meh.')

How does Python know nacho_table is a table and not an array?

def both_or_neither(nacho_table):
    reactions = nacho_table.column('Reactions')
    number_wow_reactions = np.count_nonzero(reactions == 'Wow!')
    number_meh_reactions = np.count_nonzero(reactions == 'Meh.')
    if number_wow_reactions > number_meh_reactions:
        return 'Wow!'
    elif number_wow_reactions < number_meh_reactions:
        return 'Meh.'
    else:
        return 'Okay!'
    # next condition should return 'Meh.'
    ...
    # next condition should return 'Okay!'
    ...

many_nachos = Table().with_column('Nachos', np.random.choice(nachos, 250))
many_nachos = many_nachos.with_column('Reactions', many_nachos.apply(nacho_reaction, 'Nachos'))
result = both_or_neither(many_nachos)
result
