python如何在另一个函数调用上个函数的对象。

mean_list = []

for i in range(data_array.shape [1]):

    row_mean = np.mean(data_array[:,i:i+1])

    mean_list.append(row_mean)

return mean_list

plt.scatter(setosa, versicolour,edgecolors='white')

plt.scatter(float(para_list[0]),float(para_list[1]),c='r',marker='X')

plt.xlabel('Setosa')

plt.ylabel('Versicolour')

plt.title('Setosa & Versicolour Of Iris')

plt.show()

drawScatter(data_array[:,0:1],data_array[:,1:2],getArrayMean().mean_list)
