基于字典引用生成和“未转换”的二进制字符串

Question

random_pool=[[[0, 2, 3, 1, 3, 2, 0, 1], [0, 1], [1], [0]],
 [[0, 3, 2, 1, 2, 3, 0, 1], [0, 3], [3], [1]],
 [[1, 2, 3, 0, 3, 2, 1, 0], [2, 2], [4], [2]],
 [[2, 1, 3, 0, 3, 1, 2, 0], [2, 1], [3], [3]]]


def BinaryConversion(random_pool):
    global binary_list
    binary_list = []
    binary_index = {0: (0,0), 1: (0,1), 2: (1,0), 3: (1,1)}    
    for game in range (0, len(random_pool)):
        converted = [s for num in random_pool[game][0] for s in binary_index[num]]    
        binary_list.append(converted)    
    return (binary_list)

def GeneratePopulation(random_pool, binary_list):   
    global population
    individual = []    
    population = []  
    for ind in range (0, len(binary_list)):
        individual = [binary_list[ind],random_pool[ind][2],random_pool[ind][3]] 
        population.append(individual)    
    return (population)

def BinaryReturn(population):
    binary_return_l=[]
    binary_return_index = {(0,0): 0, (0,1): 1, (1,0): 2, (1,1): 3} 
    for game in range (0, len(population)):
        returned = [s for num in population[game][0] for s in binary_return_index[num]]
        binary_return_l.append(returned)
    return(bynary_return_l)

binary =  BinaryConversion(random_pool)
print ("\n")
print ("\n",binary_list)

pop = GeneratePopulation(random_pool, binary_list)
print ("\n")
print ("\n",population)

unconverted = BinaryReturn(population)
print ("\n")
print ("\n",bynary_return_l)

大家好，我有上面的代码来执行以下操作，1-根据字典引用将整数向量转换为二进制（工作正常），2-生成一个“填充”来附加另一个列表中的项（我认为这在这里并不重要），和3-根据相同的逻辑将二进制字符串转换回数字

问题在第三部分，BinaryReturn(population)。我试图从二进制转换代码执行逆操作，但它不起作用，我得到消息KeyError: 0。有人知道我做错了什么吗

谢谢你
