marginal-tax's Issues

AttributeError: 'Series' object has no attribute 'brackets'

HI Nikhil,

I'm trying to implement your function in a project, but I'm getting this error

AttributeError: 'Series' object has no attribute 'brackets'


def income_tax(income):
    brackets = np.array([0, 12500, 50000, 150000])
    rates = np.array([0, 0.2, 0.4, 0.45])

    df_tax = pd.DataFrame({'brackets': brackets, 'rates': rates})
    df_tax['base_tax'] = df_tax.brackets.\
        sub(df_tax.brackets.shift(fill_value=0)).\
        mul(df_tax.rates.shift(fill_value=0)).cumsum()
    rows = df_tax.brackets.searchsorted(income, side='right') - 1
    income_bracket_df = df_tax.loc[rows].reset_index(drop=True)
    print(income_bracket_df)
    return pd.Series(income).sub(income_bracket_df.brackets).\
        mul(income_bracket_df.rates).add(income_bracket_df.base_tax)

print(income_tax(20200))

does your code still run?

cheers!
