The conclusion of this question is that python supports the judgment of the same mode: Row [0] = row [1] = row [2], that is, supports connections, etc.

Let's take a look at the great god code.

 

1 def checkio(result):2     rows = result3     cols = map(‘‘.join, zip(*rows))4     diags = map(‘‘.join, zip(*[(r[i], r[2 - i]) for i, r in enumerate(rows)]))5     lines = rows + list(cols) + list(diags)6  7     return ‘X‘ if (‘XXX‘ in lines) else ‘O‘ if (‘OOO‘ in lines) else ‘D‘

 

The zip function softens two arrays, such as the student name = ['bob', 'jenny '], grade = [80, 90], zip (name, grade) = [('bob', 80), ('jenny ', 90)]. In function calls, use * List/tuple to separate list/tuple, pass the parameter as a location parameter to the corresponding function (provided that the corresponding function supports an indefinite number of location parameters), such as test = ["XXX", "ooo ","... "], zip (* test) = [('x', 'O ','. '), ('x', 'O ','. '), ('x', 'O ','. ')]

The map function accepts two parameters. The first parameter is the function name, and the second parameter is an iterative object, for example, array = [1, 2, 3], map (STR, array) = ['1', '2', '3'], that is, the first function is applied to the second object.
