ThreadPoolExecutor - how do I execute both functions func1 and func2 at the same time? I see that these are not getting executed one after the other

Question

with ThreadPoolExecutor(max_workers=5) as executor:
         task1 = executor.submit(func1,argument1,argument2)
         task2 = executor.submit(func2,argument1,argument2)
         #Note this Func2 doesn't return any value
         result1, result2 = task1.result()
         result3 = task2.result()

ThreadPoolExecutor - how do I execute both functions func1 and func2 at the same time? I see that these functions are getting executed one after the other and not simultaneously .

Also kindly note func1 returns value1,value2 but func2 doesn't return any value
