There are trees between them which cannot be moved. true if inputString is a palindrome, false otherwise. There are a couple of names in your code that could be clearer, for example ip, m, and k. In particular, it seems that the parameter k in __init__, the parameter num_of_mines in allocate_mines, and the local variable m in play mean the same thing, but the parameter k in get_random_pos does not mean the same thing as the parameter k in __init__.
