Question

如何从setGen()返回多个值？

def menu():
    option = int(input("Please select an option: \n 1: Set Generation 0 Values \n 2: View Generation 0 Values \n 3: Run Model"))

    if option == 1:
        setGen()
    elif option == 2:
        displayGen()
    elif option == 3:
        runModel(juveniles,adults,seniles)#,jSrate,aSrate,sSRate,bRate,endGeneration)
    elif option == 4:
        print(adults)
    menu()


def setGen():
    #enter number of juveniles
    juveniles = int(input("How many juveniles are in the total popluation?"))
    #enter number of adults
    adults = int(input("How many Adults are in the total popluation?"))
    #enter number of seniles
    seniles = int(input("How many Seniles are in the total popluation?"))
    #enter juvenilesenile survival rates
    return(juveniles,adults,seniles)

menu()

我无法想到在函数运行时再次运行菜单的方法，而且变量似乎不会返回到调用函数

在选项1中，您正在调用setGen()，但您没有将该函数的返回值分配给变量，因此您正在丢失数据。尝试将该行更改为

juveniles,adults,seniles = setGen()

试图将多个值返回给调用函数但它不起作用
