You can print the inputs to see which tests you are failing.

Random tests are actually bad in Python, you would fail more than one test.

triangle inequality theorem,but i used that and it still didnt

Assert::That(isValidWalk(V{'e','w','w','w','n','w','w'})

There is no such test, and it should be false. (it could be one of random tests tho)

aint that hard to be honest its just the author didnt explain well ..

Hello im just so buffled and i didnt really get it i have my code now but the question has some points that didnt really explain clearly like this
Assert::That(isValidWalk(V{'n','s','n','s','n','s','n','s','n','s'}) // it is true since the size is 10

Assert::That(isValidWalk(V{'e','w','w','w','n','w','w'}) // SHOULD BE TRUE??? btw this is the input of the test .. how come this is true when every char is 1 min and this isnt even in 10 minutes just like the author said

Your function is returning strings, not booleans, not a kata issue. Read this: https://docs.codewars.com/training/troubleshooting/
