python之在 Python 中解压的值太多

我正在尝试制作一款战舰游戏，但我一直停留在舰船生成阶段。 当我尝试运行它时:

初始化

print "Welcome to Battleships!!!" 
board = [] 
import os 
from random import randint 
 
for x in range(10): 
    board.append(["O"] * 10) 
 
def print_board(board): 
    for row in board: 
        print " | ".join(row) 
 
ships = {"battleship" : [5], "cruiser1" : [4], "cruiser2" : [4], "frigate1" : [3], "frigate2" : [3], "frigate3" : [3], "frigate4" : [3], "minesweeper1" : [2], "minesweeper2" : [2], "minesweeper3" : [2], "minesweeper4" : [2]} 
numbers1 = [] 
numbers2 = [] 
numbers = [] 

一些设置函数

def setup_nums1(): 
    for count1 in range(6): 
        for count2 in range(10): 
            number1 = (count1)*100 
            number2 = count2 
            numbers1.append(number1 + number2) 
def setup_nums2(): 
    for count1 in range(10): 
        for count2 in range(6): 
            number1 = (count1)*100 
            number2 = count2 
            numbers2.append(number1 + number2) 
def setup_nums(): 
    for count1 in range(10): 
        for count2 in range(10): 
            number1 = (count1)*100 
            number2 = count2 
            numbers.append(number1 + number2) 
def setup_numbers(): 
    setup_nums() 
    setup_nums1() 
    setup_nums2() 
def setup_ships():  
    x = 59  
    for ship, info in ships: 
        direction = randint(1,2) 
        if direction == 1: 
            ships[ship].append(numbers1[randint (0,x)]) 
            y = info[1] 
            print y 
            numbers1.remove(y) 
            if y in numbers2: 
                numbers2.remove(y) 
            numbers.remove(y) 
            x = x - 1 
            for n in range(ship[0]): 
                ships[ship].append(y + n  + 1) 
                numbers1.remove(y + n + 1) 
                if (y + n + 1) in numbers2: 
                    numbers2.remove(y + n + 1) 
                numbers.remove(y + n + 1) 
                x = x - 1                 
        if direction == 2: 
            ships[ship].append(numbers2[randint (0,x)]) 
            y = info[1] 
            print y 
            numbers2.remove(y) 
            if y in numbers1: 
                numbers1.remove(y) 
            numbers.remove(y) 
            x = x - 1 
            for n in range(ship[0]): 
                ships[ship].append(y + n*100  + 100) 
                numbers2.remove(y + n*100 + 100) 
                if (y + n + 1) in numbers1: 
                    numbers1.remove(y + n*100 + 100) 
                numbers.remove(y + n*100 + 100)   
                x = x - 1 

主程序

setup_nums1() 
setup_nums2() 
setup_ships() 
print numbers1 
print numbers2 
print ships 

我收到这个错误:

Welcome to Battleships!!!
