Question

我刚刚在Python编写了一个简单的战舰游戏。在终端中，它运行完美，但是当我尝试在线运行它作为cgi-bin脚本时，存在问题。我的代码是：

#!/usr/bin/python

print "Content-type: text/html\n\n"
print "<html>"

from random import randint

board = []

for x in range(0,5):
  board.append(["O"] * 5)

def print_board(board):
  for row in board:
    print " ".join(row)

print_board(board)

def random_row(board):
  return random.randint(0,len(board)-1)

def random_col(board):
  return random.randint(0,len(board[0])-1)

ship_row = random_row(board)
ship_col = random_col(board)
guess_row = raw_input("Guess Row:")
guess_col = raw_input("Guess Col:")

print ship_row
print ship_col

if (guess_row == ship_row and guess_col == ship_col):
print "Congratulations! You sank my battleship!<br/>"
else:
if board[guess_row][guess_col] == "X":
print "You guessed that one already.<br/>"
if not (0 <= guess_row < len(board)) or not (0 <= guess_col < len(board)):
print "Oops, that’s not even in the ocean.<br/>"
else:
print "You missed my battleship!<br/>"
board[guess_row][guess_col] == "X"
print_board(board)

print "</html>"

我应该提一下，其他简单的hello-world脚本在网页中运行正常。错误日志根据这个返回这些行：

你能帮我解决这个问题吗？

提前致谢！

试试这个：

#!/usr/bin/python

print "Content-type: text/html\n\n"
print "<html>"

from random import randint

board = []

for x in range(0,5):
    board.append(["O"] * 5)

def print_board(board):
    for row in board:
        print " ".join(row)

print_board(board)

def random_row(board):
    return random.randint(0,len(board)-1)

def random_col(board):
    return random.randint(0,len(board[0])-1)

ship_row = random_row(board)
ship_col = random_col(board)
guess_row = raw_input("Guess Row:")
guess_col = raw_input("Guess Col:")

print ship_row
print ship_col

if (guess_row == ship_row and guess_col == ship_col):
    print "Congratulations! You sank my battleship!<br/>"
elif board[guess_row][guess_col] == "X":
    print "You guessed that one already.<br/>"
if not (0 <= guess_row < len(board)) or not (0 <= guess_col < len(board)):
    print "Oops, that’s not even in the ocean.<br/>"
else:
    print "You missed my battleship!<br/>"
board[guess_row][guess_col] == "X"
print_board(board)

print "</html>"

邮政有点旧，但万一有人在看：

尝试运行此程序（从浏览器中）以查看其是否有效：

#!/usr/bin/python
import cgi
cgi.test()

如果没有出现错误，请尝试删除该文件，制作一个新文件并将代码复制/粘贴回来。
