Python Codecademy 9单元Battleship!

Posted 2020-08-03 十月的雨

from random import randint 
#引入随机函数

board = []  
#建一个空的list

for x in range(5):
    board.append(["O"] * 5)   
#用range()方法给list写值，每一个["0"]*5是item

def print_board(board):
    for row in board:
        print " ".join(row) 
#输出list，去掉引号和括号，用空格连接

print "Let‘s play Battleship!"
print_board(board)


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)
    
    # Everything from here on should go in your for loop!
    # Be sure to indent four spaces!
for turn in range(4):  
#循环四次
    guess_row = int(raw_input("Guess Row:")) 
#输入猜测值
    guess_col = int(raw_input("Guess Col:"))
    
    if guess_row == ship_row and guess_col == ship_col:
        print "Congratulations! You sunk my battleship!"
        break
    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"):
#如果已经被填充X说明是重复值
            print "You guessed that one already."
        else:
            print "You missed my battleship!"
            board[guess_row][guess_col] = "X"  
#猜错的值用X填充
        print (turn+1)
        if turn==3:
            print "Game Over"
    print_board(board)

 

 codecademy第九单元的小游戏，虽然通过了，但是感觉还有硬伤，需要后期再调一下，例如轮次是从0开始的，输入的第几行第几列是不是应该-1，输入的数值没有判空
