【问题描述】：

这是我的战舰游戏代码，我不断收到错误消息 "Type error: unorderable types: str() < int()"

这条消息出现在行

if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):

完整代码如下：

import random

board = []

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

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

print ("Let's play Battleship!")
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)
print (ship_row)
print (ship_col)

for turn in range(4):
    guess_row = input("Guess Row:")
    guess_col = input("Guess Col:")

    if guess_row == ship_row and guess_col == ship_col:
      print ("Congratulations! You sunk my battleship!")
      break
    else:
        if turn == 3:
            board[guess_row][guess_col] = "X"
            print_board(board)
            print ("Game Over")
            print ("My ship was here: [" + str(ship_row) + "][" + str(ship_col) + "]")
        else:
            if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):
                print ("Oops, that's not even in the ocean.")
            elif(board[guess_row][guess_col] == "X"):
                print ("You guessed that one already.")
            else:
                print ("You missed my battleship!")
                board[guess_row][guess_col] = "X"
            print (turn + 1)
            print_board(board)

【问题讨论】：

请修正您的格式，谢谢！
看到错误信息，你的guess_row和guess_col有可能是字符串吗？然后把它们变成整数就可以了： if (int(guess_row) 4) or (int(guess_col) 4):
当您 inputguess_row 和 guess_col 的值是字符串时。将它们转换为整数。

标签： python

【解决方案1】：

input 将输入读取为字符串。您必须将其转换为 int：

guess_row = int(input("Guess Row:"))
guess_col = int(input("Guess Col:"))

【解决方案2】：

此错误表示您的变量 guess_row 和 guess_col 是字符串而不是整数，您正在尝试将它们与整数进行比较。

进行比较时，只需使用int(guess_row) 和int(guess_col) 将它们转换为整数即可。
