from statsmodels.sandbox.stats.runs import mcnemar
f_obs = np.array([[20, 21],[43, 16]])
(statistic, pVal) = mcnemar(f_obs)
print('p = {0:5.3e}'.format(pVal))
if pVal < 0.05:
    print("There was a significant change in the disease by the treatment.")

p = 8.147e-03
There was a significant change in the disease by the treatment.
