Question

当我输入正确的整数以调用hit（）或miss（）时，print语句将第一次打印到控制台，但此后不打印到控制台。每次都会调用players_turn（）函数，但不会调用print语句。我的控制台也没有出现任何错误

import numpy as np
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))

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

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

ship_row = random_row(board)
ship_col = random_col(board)

def players_turn():
    for turn in range(4):
    print ("turn", turn +1)
    guess_row = int(raw_input("Guess Row: "))
    guess_col = int(raw_input("Guess Col: "))

def hit():
    print ("direct hit")
    board[guess_col][guess_row] = "H"
    print_board(board)
    players_turn()

def miss():
    print ("you missed, try again")
    board[guess_col][guess_row]
    print_board(board)
    players_turn()

def out_of_range():
    print ("this is out of the range of the battle field")
    players_turn()

if_yes = str(raw_input("Do you want to play Battleship? "))

if if_yes == 'yes':
    print ship_row
    print ship_col
    guess_row = int(raw_input("Guess Row: "))
    guess_col = int(raw_input("Guess Col: "))

if guess_col == ship_col and guess_row == ship_row:
    hit()
elif guess_col not in range(5) or guess_row not in range(5) :
    out_of_range()
else:
    miss()

我希望每次输入正确的hit（）凭据时，我都会得到： “直接命中”，棋盘将被打印到控制台。如果符合miss（）凭证，我将得到： “您错过了，再试一次”，然后将打印出木板。

您的代码存在多个问题。我在不做太多修改的情况下移动了您的代码。我使用Python 3.7。这里是问题。

raw_input已停产。请改用input。
在Python 3.x中使用print作为函数。因此，您需要括号。如果您使用的是Python 2.x，则可以忽略它。
用户回答“是”后，他们应该进入循环players_turn。因此，其余的输入请求和函数调用都在其下。否则，它只会要求用户输入而不会执行任何操作
现在，您正在遍历players_turn时，不要从hit，miss和out_of_range等其他函数中调用它。
我也看不到在任何地方使用numpy。
匹配项不会打印到右行和右列。我没有提到那个。我只解决了印刷问题。

这是更新的代码

import numpy as np
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))

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

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

def hit():
    print ("direct hit")
    board[guess_col][guess_row] = "H"
    print_board(board)

def miss():
    print ("you missed, try again")
    board[guess_col][guess_row]
    print_board(board)

def out_of_range():
    print ("this is out of the range of the battle field")

def players_turn():
    for turn in range(4):
        print ("turn", turn +1)
        guess_row = int(input("Guess Row: "))
        guess_col = int(input("Guess Col: "))
        if guess_col == ship_col and guess_row == ship_row:
            hit()
        elif guess_col not in range(5) or guess_row not in range(5) :
            out_of_range()
        else:
            miss()

ship_row = random_row(board)
ship_col = random_col(board)

if_yes = str(input("Do you want to play Battleship? "))

if if_yes == 'yes':
    print (ship_row)
    print (ship_col)
    players_turn()

每次调用函数
