And Seek...the code looks right, but why it report error?


#1



Here is my code, I think it is right, but it report the error as: "Oops, try again. Your code threw the following error: invalid literal for int() with base 10: ''
Also showed: "Traceback (most recent call last):
File "python", line 21, in
ValueError: invalid literal for int() with base 10: ''

I really puzzled, can you help me?

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)

guess_row= int(raw_input( 'Guess Row: '))
guess_col= int(raw_input( 'Guess Col: '))# Add your code below!

what do you enter when you are prompted? This should be numbers, otherwise you can't pass.


#3

yes, I entered the numbers, and less than 5.


#4

the only way i reproduce your error message is by entering blank:

Guess Row:  
Traceback (most recent call last):
  File "python", line 21, in <module>
ValueError: invalid literal for int() with base 10: ''

so you entered blank, or you hit a glitch. Try a different browser

Yep, thanks a lot. A different browser works!
