How to execute multiple functions at the same time in python?

Question

Python

Now there are two functions how to start their execution in a loop and interrupt the execution of the first one if the second condition is met, now the only thought is to put the content in endless loops and start executing

what is:

def fishing():
    pyautogui.keyDown('space')
    time.sleep(1.65)
    pyautogui.keyUp('space')
    time.sleep(3)
    x = 0
    while x != 35:
        pyautogui.keyDown('space')
        time.sleep(1)
        pyautogui.keyUp('space')
        x += 1
        continue
    pyautogui.keyDown('space')
    time.sleep(15)
    pyautogui.keyUp('space')

def its_fish():
    if pyautogui.locateOnScreen('qwe.PNG') == None:
        print("рыбы нет")
    else:
        pyautogui.click(x=130, y=801)
        pyautogui.click(pyautogui.locateCenterOnScreen('qwe.PNG'))
        print('Опа Рыбка')
