# binning

def bin$\_$fruits$($fruit$\_$prices$)$:

$\text{'}\text{'}\text{'}$

cheap $-$ less than $3($not inclusive$)$

affordable $-$ between $3$ and $6($both inclusive$)$

costly $-$ greater than $6($not inclusive$)$

Arguments:

fruit$\_$prices: dict $-$ dictionary with fruits as keys and prices as values

Return:

binned$\_$fruits: dict $-$ dictionary with category as key and a set of fruits in that category as values.
