Python minesweeper game - user chooses grid size and how many mines
I have the following python code but I'm really struggling to get it to work.
It's a basic minesweeper game in terminal. This version is a little different to the others out there in that it's supposed to start by asking the user how big the grid, then how many mines to insert. The rest of it is your good old basic minesweeper.
def display():
for x in range(SIZE):
if x == 0:
print(" ", end="")
for i in range(SIZE):
print(" " + str(i), end="")
print("\n |-" + "--|-" * (SIZE - 1) + "--|")
print("0 |", end="")
for y in range(SIZE):
print(" " + str(BOARD[x][y].status) + "|", end="")
print("\n |-" + "--|-" * (SIZE -1) + "--|")
elif x == SIZE -1:
print(str(SIZE-1) + " |", end="")
for y in range(SIZE):
print(" " + str(BOARD[x][y].status) + "|", end="")
print("\n |-" + "--|-" * (SIZE -1) + "--|")
else:
print(str(x) + " |", end="")
for y in range(SIZE):
print(" " + str(BOARD[x][y].status) + "|", end="")
print("\n |-" + "--|-" * (SIZE-1) + "--|")

def status_get(self):
return this.status
def first_move():
# establish mine locations, ignoring stating dig

while True:

Here's a slightly reorganized version of your code that works. You forgot to call first_move. You were inconsistent in whether status had to include the trailing blank (I'm not using it). If changes all your while loops so they break on success; that avoids the confusion. Notice there is only one global here.
import random
def display():
for x in range(SIZE):
if x == 0:

print("0 |", end="")
for y in range(SIZE):
print(" " + str(BOARD[x][y].status) + " |", end="")
print("\n |-" + "--|-" * (SIZE -1) + "--|")
elif x == SIZE -1:
print(str(SIZE-1) + " |", end="")
for y in range(SIZE):
print(" " + str(BOARD[x][y].status) + " |", end="")
print("\n |-" + "--|-" * (SIZE -1) + "--|")
else:
