Can't read value in Function from Flask

Question

I have this problem and i new in python (alone and with flask).

I need to use the value of testRun on a loop in the function record_loop, and this variable change on the flask event testConfig when i have a Get or Post. But the variable always read '0' in the function record_loop. I know the variable change inside the flask event, when i do a Post.

What i do wrong
