python - Indent Error with my battleship.py script -

i'm trying create simple 2 player game classic battleship. hence i'm beginning learn python , i'm keeping simple. have created 5x5 grid , want players (2) able place 1 ship 1x1 anywhere on board. take turns guessing other person placed ship.

when compiled code got indent error on line 61 "else: ". i'm aware "h" , "m" hit , miss overlap since i'm outputting same playing board.

i guess need while loops in code.

your indentation incorrect... @ this:

while true:     while true:         print "player 1 turn"         user1_guess = [user_row(), user_col()]         if user1_guess == user2_ship:             board[user1_guess[0]][user1_guess[1]] == "h"             print "player 1 wins!"     break 

the break statement must have same indentation print statement this:

while true:     while true:         print "player 1 turn"         user1_guess = [user_row(), user_col()]         if user1_guess == user2_ship:             board[user1_guess[0]][user1_guess[1]] == "h"             print "player 1 wins!"             break 

if have time, please read python styleguide improve quality of code.
