Thread issue about dxcam HOT 1 OPEN

Simple create a list, and somehow let it work like a lock
a = [0, 0]
lets say a[0] represents status of thread 1, and a[1] for thread 2
Since you have sleep(0.1) which helps decrease errors
So in each thread, right before you take a screenshot, you check first if there are 1 in a, if not then you set value from 0 to 1, and set back to 0 when done screenshot

For example:

def reading():
    time.sleep(1)
    while True:
        while (1 in a):
            pass
        a[1] = 1
        wnd.read_window_frame(window)
        a[1] = 0
        print("reading frame 2")
        time.sleep(0.1)
