Question

python如何在另一个函数调用上个函数的对象

Answer 1

def getArrayMean(data_array):
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

def drawScatter(setosa, versicolour,para_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)

后一个函数怎么用上一个函数里的mean_list？
