(parser() fill in numbers of adjacent mines each square)
i don't understand why function cause trouble before called. no mine field appears when it's called. please kindly give me suggestions. thanks!
the reason nothing shows because using both pack , grid on widgets children of root window. within given window must use 1 or other.
