Python: TypeError: 'function' 对象没有属性 '__getitem__'

我是 python 的新手，我在处理一些代码时遇到了问题。我遇到了错误

TypeError: 'function' object has no attribute '__getitem__' at line 32 

我不知道发生了什么。从我在 Internet 上看到的内容来看，这意味着将函数用作列表，但我无法用我的代码弄清楚。我的代码是

#! /usr/local/bin/python 
 
 
import random 
 
 
def genFirstGen(): 
    print "First Generation" 
    generation = [] 
    for chromosomecounter in range(0, 20): 
        chromosome = [] 
        fitness = 0 
        for genecounter in range(0, 10): 
            chromosome.append(random.randrange(0, 2)) 
        for genecounter in range(0, 10): 
            if (chromosome[genecounter] == 1): 
                fitness += 1 
        chromosome.append(fitness) 
        generation.append(chromosome) 
        print gene 
    return generation 
 
 
def FindMostFit(generation): 
    failedset = [0,0,0,0,0,0,0,0,0,0,0] 
    highestfitness = 0 
    mostfit = 0 
    fitparents = [] 
    gene = [] 
    for fitcounter in range(0, 10): 
        for chromosomecounter in range(0, 20): 
            chromosome = [generation[chromosomecounter]] #  The error is here. 
            fitness  = chromosome[10] 
            highestfitness = 0 
            if (fitness > highestfitness): 
                highestfitness = fitness 
                mostfit = chromosomecounter 
 
        fitparents.append(generation[mostfit]) 
        generation[mostfit] = failedset 
    return fitparents 
 
 
def BreedMostFit(Parents): 
    Mother = Parents(random.randrange(0, 10)) 
    Father = Parents(random.randrange(0, 10)) 
    child = [] 
    for genecounter in range(0, 5): 
        parentgenetaken = random.randrange(0, 2) 
        if (parentgenetaken == 1): 
            child.append(Mother[genecounter * 2]) 
            child.append(Mother[(genecounter * 2) + 1]) 
        else: 
            child.append(Father[genecounter * 2]) 
            child.append(Father[(genecounter * 2) + 1]) 
    return child 
 
 
def Generation2(): 
    newgeneration = [] 
    for gencounter in range(0, 20): 
        newgeneration.append(BreedMostFit(FindMostFit(genFirstGen))) 
    return newgeneration 
 
def GenerationFunction(parentgen): 
    generation = [] 
    for gencounter in range(0, 20): 
        generation.append(BreedMostFit(FindMostFit(parentgen))) 
    return generation 
 
GenerationFunction(Generation2()) 

我已经无计可施了。谁能帮忙？谢谢!

请您参考如下方法:

在第 62 行，您将 genFirstGen 函数传递给 FindMostFit

newgeneration.append(BreedMostFit(FindMostFit(genFirstGen))) 

稍后在第 32 行索引它。我猜您想调用该函数并传递其结果。所以将第 62 行替换为

newgeneration.append(BreedMostFit(FindMostFit(genFirstGen())))
