How this actually works?

Hi there!
I saw this code in this repo

def check_cpu_filed():
    # Define the bpf program for checking purpose
#if LINUX_VERSION_CODE < KERNEL_VERSION(5,16,0)
    filed_in_task_struct = True
#else
    filed_in_task_struct = False
#endif

    return filed_in_task_struct

And i don't understand how it works. AFAIK there is no ifdef in python. Does that mean that function always return false?
