players has a .name property. I thought part of the fun was that you can't see the property by viewing the list.
It is there. Try print(players[1].name)

I print the players in python and result is as follows:
[<main.Player object at 0x7ffbf3a11828>,
<main.Player object at 0x7ffbf27b6ef0>,
<main.Player object at 0x7ffbf27b6860>,
<main.Player object at 0x7ffbf27b66a0>,
<main.Player object at 0x7ffbf27b6668>,
<main.Player object at 0x7ffbf27b6470>,
<main.Player object at 0x7ffbf27b6630>,
<main.Player object at 0x7ffbf27b6438>,
<main.Player object at 0x7ffbf27b6518>,
<main.Player object at 0x7ffbf27b6358>]

Is codewars changing something in test framework in buggy way, or this cata is not ready for python?

Print the players array to the console. The array used in the example test cases is different than the array used in the description.
