some randome tests gone wrong, i check few they should give other result for example
's', 'e', 'e', 'n', 'n', 's', 'e', 'w', 'n', 's' should give False as i checked, function gave False, but test shown this incorrect,anyway it was funny, i tryed with class and tests on myown pycharm, it was good practice.
s: 0 -1
e: 1 -1
e: 2 -1
n: 2 0
n: 2 1
s: 2 0
e: 3 0
w: 2 0
n: 2 1
s: 2 0
final: 2 0
Walk was not so perfect

in example, looks, like some randome tests not works correctly
