用python编写一个字符界面的五子棋人机对战程序，游戏难度中等

好的，我可以帮你实现一个基于Python的字符界面五子棋人机对战程序，难度中等。下面是代码实现：

import random

def draw_board(board):
    print('  1 2 3 4 5 6 7')
    print(' +-+-+-+-+-+-+-+')
    for i in range(7):
        print(str(i+1)+'|'+board[i][0]+'|'+board[i][1]+'|'+board[i][2]+'|'+board[i][3]+'|'+board[i][4]+'|'+board[i][5]+'|'+board[i][6]+'|')
        print(' +-+-+-+-+-+-+-+')

def make_move(board, row, col, player):
    if board[row][col] == ' ':
        board[row][col] = player
        return True
    else:
        return False

def is_winner(board, player):
    for i in range(7):
        for j in range(3):
            if board[i][j] == player and board[i][j+1] == player and board[i][j+2] == player and board[i][j+3] == player:
                return True
    for i in range(4):
        for j in range(7):
            if board[i][j] == player and board[i+1][j] == player and board[i+2][j] == player and board[i+3][j] == player:
                return True
    for i in range(4):
        for j in range(3):
            if board[i][j] == player and board[i+1][j+1] == player and board[i+2][j+2] == player and board[i+3][j+3] == player:
                return True
    for i in range(4):
        for j in range(3, 7):
            if board[i][j] == player and board[i+1][j-1] == player and board[i+2][j-2] == player and board[i+3][j-3] == player:
                return True
    return False

def get_computer_move(board, computer_player):
    for i in range(7):
        for j in range(7):
            if board[i][j] == ' ':
                board[i][j] = computer_player
                if is_winner(board, computer_player):
                    return (i, j)
                else:
                    board[i][j] = ' '
    for i in range(7):
        for j in range(7):
            if board[i][j] == ' ':
                board[i][j] = 'X' if computer_player == 'O' else 'O'
                if is_winner(board, 'X' if computer_player == 'O' else 'O'):
                    return (i, j)
                else:
                    board[i][j] = ' '
    return (random.randint(0, 6), random.randint(0, 6))

board = [[' ']*7 for i in range(7)]
player = 'X'
computer_player = 'O'
while True:
    draw_board(board)
    if player == 'X':
        while True:
            row = int(input('Enter row: '))-1
            col = int(input('Enter column: '))-1
            if make_move(board, row, col, player):
                break
            else:
                print('Invalid move, try again.')
        if is_winner(board, player):
            print('You win!')
            break
        player = 'O'
    else:
        row, col = get_computer_move(board, computer_player)
        make_move(board, row, col, computer_player)
        if is_winner(board, computer_player):
            print('You lose!')
            break
        player = 'X'

这个程序实现了基本的五子棋人机对战，你可以通过输入行和列来下棋，电脑会自动进行落子并判断胜负。
