How to reload ebpf program via python-bcc?

When I modify the ebpf code in "networking/http_filter/http-parse-complete.c", and exit the python program via Ctrl-C again and again to debug my program, the old ebpf code is not unloaded and removed.

I have added a version code to verify if the code is the newest. But the version does not change no matter how I change the ebpf code.
bpf_trace_printk("tcp: %d %d\n", version, payload_offset);

Is there a function such as "remove_xdp" to remove the existing ebpf SOCKET_FILTER program immediately?

How to update the SOCKET_FILTER ebpf program successfully? Currently, I need to reboot the system.

Keyword: reload, clean, remove, remove func , unload func

Start with networking/http_filter/http-parse-complete.c and the Python-BCC program that loads its SOCKET_FILTER program. Reproduce repeated Ctrl-C exits, then inspect how the existing program is unloaded and replaced. Done means the modified eBPF code is loaded successfully without rebooting and the changed version is observable.
