如何正确显示两个数字文本文件?

这是我的密码

        with open("ingredient.txt", 'r', encoding="utf8") as f1:
            myarray = f1.readlines()

        with open("quantity.txt", 'r', encoding="utf8") as f2:
            myarray2 = f2.readlines()  

        with open("demand.txt", 'r', encoding="utf8") as f3:
            myarray3 = f3.readlines()


        for element1,element7,element0 in zip(myarray, myarray2, myarray3):
            element1 = element1[:-1]
            element7 = element7[:-1]
            element0 = element0[:-1]
            print(f'{element1:<35}{element7:<11}{element0:>7}')

文件: demand.txt = 30,20,50 quantity.txt = 10,10,1 ingredient.txt= tomato,tomato,tomato

我在终端里得到的是 tomato 10 30 tomato 10 20 tomat 5 并列

结果应该是 番茄1020 tomato 1 50

提前谢谢!
