Hello from ThreefoldVM
Your Python interpreter runs as a virtual machine, executing this program. This program is also a virtual machine, and the instructions it executes create a new virtual machine.
That's all I have to say.
Some example: [FrameInfo(frame=<frame at 0x1004f7130, file '/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', line 175, code AS>, filename='/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', lineno=175, function='AS', code_context=['def AS():B._+=1;E=G.copy();D=C[B._];F=A.pop()if D&1 else();H=A.pop()if D&2 else{};I=A.pop()(*F,**H);J=G.copy();E==J and A.append(I)\n'], index=0), FrameInfo(frame=<frame at 0x11c72f840, file '/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', line 219, code H>, filename='/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', lineno=205, function='H', code_context=['\t\t\t\tif W[C[B._]]():K=A.pop();break\n'], index=0), FrameInfo(frame=<frame at 0x1004f7300, file '/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', line 175, code AS>, filename='/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', lineno=175, function='AS', code_context=['def AS():B._+=1;E=G.copy();D=C[B._];F=A.pop()if D&1 else();H=A.pop()if D&2 else{};I=A.pop()(*F,**H);J=G.copy();E==J and A.append(I)\n'], index=0), FrameInfo(frame=<frame at 0x10045da40, file '/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', line 230, code <module>>, filename='/Volumes/IOPCC/submissions2023/1614876765/step2obf.py', lineno=230, function='<module>', code_context=['\ttry:W[C[B._]]()\n'], index=0)]
