python在文件中输入整数

    a=[]
    b=[]
    for i in range(len(predicted)):
        b.append((int)(float(predicted[i])))
        a.append(int(test_set.label[i][0]))

    f=open('F:/goverment/ArticleMining/predict.txt', 'w')
    for i in range(len(predicted)):
       f.write(str(b[i]))
       f.write('\n')
    f.write("写好了")
    f.close()
