Now, Python 3.13 adds new elements to the JIT that generate actual machine code at runtime, instead of just specialized bytecode. The resulting speedup isn’t much just yet—maybe 5%—but it ...

For example, The Specializing Adaptive Interpreter introduced in Python 3.11 (PEP 659) would rewrite the bytecode instructions in place with type-specialized versions as the program ran.

What’s the deal with PyXL? “It’s actual Python executed in silicon,” notes the project site. “A custom toolchain compiles a .py file into CPython ByteCode, translates it to a custom ...

Using PYC files to hide malicious code Compared to the similar Node.js campaign reported by Securonix, in this case, attackers stored the malicious code in Python bytecode (PYC) files. This is ...

According to ReversingLabs reverse engineer Karlo Zanki, this could be the first instance of a supply chain attack capitalizing on the direct execution capability of Python byte code (PYC) files. The ...

This way you can run scripts without being connected to a PC. Scripts can also be pre-compiled to Python bytecode (so-called .mpy files) to enable faster loading at runtime. – Via frozen code ...

Recently there was a supplemental compiler project that even takes Python code and compiles it into VM byte-code. What a nice abstraction tool for making inexpensive microcontroller-based designs ...

As of Python 3.12, the GC runs only on the “eval breaker” mechanism in the Python bytecode loop—that is, between executing one bytecode and another. It also runs whenever CPython’s signal ...
