[Tutor] How to stop a specific thread in Python 2.7?

[marc nicole]

Why i want to kill a thread?

At first, i want to look for two values through a thread, if i got them
before an event happens, that's cool, the thread will end itself and i will
use the values in the subsequent code, if not i want to kill the background
running function/thread, and relaunch the function of thread (blocking call
this time) to get the values and then continue the program.

The context is robotics:

The robot should run the thread in the state idle to get values needed for
a task, but if the user talks to him and the values weren't captured yet,
the robot should run the function again in a blocking manner until he gets
the values for the task, while stopping the initial call to it through the
thread.
