ImportError: cannot import name 'BPF' from 'bcc' (unknown location)

I have built bcc from source.
The directory where it was built was:
/home/pegasus_vm/Documents/eBPFShield/bcc/build
When I try to run python main.py -h
It throws the following error:
`ImportError: cannot import name 'BPF' from 'bcc' (unknown location)`
How to fix it?

I've also added bpf build to the path like this in `~/.bashrc`:
```
bcctools=/home/pegasus_vm/Documents/eBPFShield/bcc/build/tools
bccexamples=/home/pegasus_vm/Documents/eBPFShield/bcc/build/examples
export PATH=$bcctools:$bccexamples:$PATH
```

Start by reproducing `python main.py -h` and checking how Python resolves `bcc` after the source build in `/home/pegasus_vm/Documents/eBPFShield/bcc/build`. Review the built tools, examples, and the `~/.bashrc` PATH entries to determine whether the Python binding containing `BPF` is available; done means the command imports `BPF` successfully.
