yeah... nvm

Printing the input and debugging your code?

Simple tests pass, but random don't. And how am I supposed to know what exactly werong? :/

Approved

The LED will only blink once even if the button is held down.

In the second case Red: "01001000", Blue: "01011100", it should be "RBB" not "RB". My logic is that when press the blue button and tab the red, it should blink blue

I'm 100% in agreement with your logic, and the description should definitely be updated with some clarification. Here's how I would describe the circuit.

• The circuit has an internal state that is determined by the sequences of button inputs. This state is either OFF, RED, or BLUE.
• When the circuit changes into either the RED or BLUE state from a previous, different state, the corresponding red or blue LED will blink once.
• When no buttons are currently being pressed, the circuit is in the OFF state (the initial state of the circuit).
• When a single button is being pressed, the circuit is in the state that matches the color of the button.
• When the circuit is in the OFF state and both buttons are then pressed, the circuit switches to the RED state.
• When the circuit is in either the RED or BLUE state and the matching button is held down, the circuit will remain in its current state.

python new test frameworks

Quite simple and funny coding challenge to solve, well done.

ok letmedie sps paka

python new test framework is required. updated in this fork
