【问题描述】：
我是 python 新手，我遇到了一些代码问题。我收到了错误
TypeError: 'function' object has no attribute '__getitem__' at line 32
我不知道发生了什么。从我在互联网上看到的情况来看，这意味着将函数用作列表，但我无法用我的代码弄清楚这一点。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())
我已经束手无策了。任何人都可以帮忙吗？谢谢！

您好，欢迎来到 StackOverflow。您能否写下哪一行产生错误以及在什么调用上？您的代码很长，不清楚问题出在哪里。
