错误出现在这里：

    def run():
    print("Juvenile" + " " + "Adult" + " " + "Senile")
    for i in range(0, pop_model):
        newjuv = b.displayAdpop()* b.displayBirthrate()
        newsen = b.displayAdpop() * b.displayAdRate()
        newadu = a.displayJuvpop() * a.displayjuvRate()

        print(i + 1,newjuv, newadu,newsen)

        a.displayJuvpop() = newjuv
        b.displayAdpop() = newsen
        c.displaySepop() = newadu

出现错误＆＃34;无法分配到功能调用，第60行和第34行。由于堆栈溢出的代码到文本限制，我删除了不相关的程序部分，如导出数据和显示值。

Ps：这不是缩进错误，复制和粘贴有点中断它。

Answer 1

您的display*pop()函数返回值，而不是变量。您无法分配该功能结果。只需直接分配属性：

a.pop = newjuv
b.pop = newsen
c.pop = newadu

＆＃34;无法分配到功能调用＆＃34; Python错误
