ValueError: invalid literal for int() with base 10: ‘SCT’"

platform_issue

#1

I am getting a error " Traceback (most recent call last): File “python”, line 28, in <module> ValueError: invalid literal for int() with base 10: ‘SCT’"
for the code:
guess_row = int(raw_input("Guess Row: "))
guess_col = int(raw_input("Guess Col: "))

The error doesn’t show up every turn that I run either. What does the error mean?

its a bug, the lessons enters a string ('SCT') into the prompt of raw_input.

you could use the get solution button or hard code the values:

guess_row = 3
guess_col = 2

to get around the issue.

I am also getting the same error .How to solve it?

i covered that in my reply?

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)

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)
print ship_row
print ship_col

for turn in range(4):
print “Turn”, turn + 1

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

Write your code below!

if guess_row == ship_row and guess_col == ship_col:
print “Congratulations! You sank my battleship!”
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_board(board)
if turn == 3:
print “Game Over”

correct me please
