thank you, rowcased
with abs code works properly.
google advises me to use math.fab ))
as regards my code I know it is not optimal. I hope when I will be 2 kyu or higher it will be better ))

rowcased, can I send you my code for this kata?

pycharm result = 3
pytho console = 0

expected = 1

thanks for idea.
but I found an issue:
console

import math
print (math.fabs(-9223372036854775807)%2)
0.0

PyCharm:

Python. Attempt stage: all tests are passed, except this one
" 0 should equal -9223372036854775807 "
and I can't see the initial list to check my code.
