索引器错误：列表索引超出了创建变量结构库的范围

Question

嗨，我正在尝试建立一个不同组合的模型结构库。结构库基于5个变量，我需要5个模型。i-e modelsOne，modelsTwo等等，最多5个。为了简单起见，我将代码粘贴成束，这对所有五个模型都是一样的。它几乎没有什么变化。 当我执行代码时，我得到以下错误

modelOne = modelsOne[temp1]

IndexError: list index out of range

def ModelsProduct(modelsOne, modelsTwo, modelsThree, modelsFour,modelsFive):


    modelsStepOne = list(product("+-",repeat = 4))
    modelsStepThree = [('a','a'),('a','b'),('a','c'),('a','d'),('a','e'),('b','b'),('b','c'),('b','d'),('b','e'),('c','c'),('c','d'),('c','e')]
    modelsStepFour = [('d','d'),('d','e')]
    modelsStepFive = [('e','e')]



    #produce modelsOne
    modelsStepTwo = [('d',),('e',)]
    for one in modelsStepOne:
        for two in modelsStepTwo:

                        modelsOne.append(one+two+three+four+five)

    #produce modelsTwo

在您的代码中，以下列表的长度是16

list(product("+-",repeat = 4))

但是，看起来temp1是 temp1 = 3071

所以，当你接受 modelOne = modelsOne[temp1] 所以，这可能是导致错误的原因
