Thanks! noted

I have 5 full months of Python so I worked with what I knew .
Anyway the ask was to resolve, not to make it fast or beautiful.
Make more difficult kata for this grade .

In my local environment with my solution I can fail this, as expected, since 90 is smaller than 90.00000000000001:
"90.00000000000001, 1"
but all starts to work if I add more to mantissa (this one passes):
"90.000000000000001, 1" and also all floats up to 90.000000000000006.

Strange float round up from Python..

Maybe it's a good idea to put a condition so that the mantissa would not have more than 8 decimals (or how exact your location need be)

agree with Chrono79, my JS solution also works around all given tests. You should add his test case too.
Here's another I can pass:
([]}{[])
